                 Notes to Consolidated Financial Statements
                                (Unaudited)

The  interim consolidated financial statements are unaudited but,  in
the  opinion of management, reflect all adjustments necessary  for  a
fair  presentation of financial position, results of  operations  and
cash  flows for the periods presented.  These adjustments consist  of
normal,  recurring  items, except for one-time items  in  the  second
quarter  of  1999  relating  to gains  on  divestitures,  net  of  an
investment  valuation adjustment. The results of operations  for  any
interim period are not necessarily indicative of results for the full
year.  The  interim consolidated financial statements and  notes  are
presented as permitted by the requirements for Form 10-Q and  do  not
contain   certain  information  included  in  the  company's   annual
consolidated financial statements and notes.  This Form  10-Q  should
be  read  in  conjunction  with the company's consolidated  financial
statements and notes included in its 1998 Annual Report on Form 10-K.

Divestitures:
On  June  30, 1999, the company closed on the sale of Eastern Heights
Bank,  a subsidiary banking operation, and the sale of the assets  of
its  Cardiovascular  Systems business.  These divestitures  generated
cash  proceeds  of  $203 million, and net of an investment  valuation
adjustment,  resulted in a pre-tax gain of $104 million ($55  million
after  tax). This pre-tax gain is recorded as a reduction of selling,
general and administrative expenses.

Restructuring Charge:
In  1998, the company recorded a restructuring charge of $493 million
($313  million after tax), which is discussed in the 1998 Form  10-K.
During  the  six  months ended June 30, 1999, the company  terminated
1,337  employees under the plan. Because certain employees can  defer
receipt  of  termination benefits for up to 12 months, cash  payments
relate  to  both  current and previous terminations.   The  remaining
restructuring  liability as of June 30, 1999, totaled  $127  million.
Selected information relating to the restructuring charge follows.

Earnings Per Share:
The  difference  in  the  weighted  average  shares  outstanding  for
calculating  basic and diluted earnings per share is attributable  to
the assumed exercise of the Management Stock Ownership Program (MSOP)
stock  options for the three-month and six-month periods  ended  June
30,  1999  and 1998.  Certain MSOP options were not included  in  the
computation of diluted earnings per share because they would not have
had  a dilutive effect (16 million shares of common stock which  were
outstanding at June 30, 1999, at an average price of about $93.00).

               Review Report of Independent Auditors


To  the  Stockholders and Board of Directors of Minnesota Mining  and
Manufacturing Company:

We  have  reviewed  the accompanying consolidated  balance  sheet  of
Minnesota  Mining  and Manufacturing Company and Subsidiaries  as  of
June 30, 1999, and the related consolidated statements of income  for
the  three-month and six-month periods ended June 30, 1999 and  1998,
and  cash  flows for the six-month periods ended June  30,  1999  and
1998.  These  financial  statements are  the  responsibility  of  the
Company's management.

We  conducted our reviews in accordance with standards established by
the American Institute of Certified Public Accountants.  A review  of
interim   financial  information  consists  principally  of  applying
analytical  procedures  to financial data  and  making  inquiries  of
persons  responsible  for financial and accounting  matters.   It  is
substantially  less  in scope than an audit conducted  in  accordance
with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken
as a whole.  Accordingly, we do not express such an opinion.

Based  on our reviews, we are not aware of any material modifications
that should be made to the consolidated financial statements referred
to  above  for  them  to  be  in conformity with  generally  accepted
accounting principles.

We  have  previously  audited, in accordance with generally  accepted
auditing standards, the consolidated balance sheet as of December 31,
1998,  and the related consolidated statements of income, changes  in
stockholders' equity and comprehensive income, and cash flows for the
year  then  ended  (not presented herein); and in  our  report  dated
February  8,  1999,  we  expressed an unqualified  opinion  on  those
consolidated  financial statements. In our opinion,  the  information
set  forth  in  the  accompanying consolidated balance  sheet  as  of
December  31,  1998,  is fairly stated in all  material  respects  in
relation  to  the consolidated balance sheet from which it  has  been
derived.

                 Management's Discussion and Analysis of
              Financial Condition and Results of Operations

RESULTS OF OPERATIONS
Second Quarter
Worldwide sales for the second quarter totaled $3.863 billion, up 2.5
percent  from  the second quarter last year.  Volume increased  about
3.5  percent,  while  selling prices were up about  half  a  percent.
Currency  translation reduced worldwide sales by about  1.5  percent.
Currency,  while positive in the Asia Pacific area, was  negative  in
Europe and Latin America.

In  the  United  States, sales increased about 1  percent  to  $1.853
billion.   Volume  was up 2 percent, while selling prices  were  down
about  1 percent.  The Industrial and Consumer business recently  was
separated  into  two  markets:  Industrial and Electro  Markets,  and
Consumer  and  Office Markets.  In Consumer and Office Markets,  U.S.
unit sales increased 7 percent from the same quarter last year.   All
major  product  lines, with the exception of overhead projectors  and
supplies, registered solid growth. In Industrial and Electro Markets,
U.S.  volume  rose  3  percent.  The company  had  strong  growth  in
telecommunications  products  and a pickup  in  sales  of  industrial
tapes. Overall growth was restrained by market softness in industrial
abrasives. In Transportation, Safety and Specialty Material  Markets,
U.S.  volume  also increased 3 percent. Leading the  growth  in  this
business  area  were 3M products serving the automotive  and  housing
industries.  In  Health Care Markets, U.S. unit sales declined  about
1.5  percent.   The  company continued to see good growth  in  dental
products  and  health  information systems, but the  introduction  of
generic  alternatives to a branded 3M analgesic continued  to  affect
our overall U.S. health care growth.

Internationally,  sales  totaled  $2.010  billion.    Volume   abroad
increased  about 4.5 percent, while selling prices were up  nearly  2
percent. Currency translation reduced international sales by about  3
percent. European volume, impacted by economic softness, increased  a
little more than 2 percent.   In Eastern Europe, unit sales increased
6  percent.  In  the  Asia Pacific area, volume  increased  about  11
percent,  the company's fastest growth in six quarters. Dollar  sales
in  the Asia Pacific area increased about 20 percent. In Japan,  unit
sales rose more than 6 percent, despite continuing economic weakness.
In  Asia outside Japan, volume rose about 19 percent, an acceleration
in  the  growth  3M  posted in this year's first quarter.   In  Latin
America,  volume  was  down  about 3  percent,  due  to  softness  in
Argentina,  Brazil and Venezuela.  Mexico continued to  be  a  bright
spot,  with unit sales increasing about 20 percent. In Canada, volume
increased about 5 percent.

Worldwide,  all  market segments showed sales  and  operating  income
growth.   Sales  growth  was  led by increases  in  telecommunication
products,  products  serving the automotive and  housing  industries,
dental   products,  and  health  information  systems.   Growth   was


<PAGE> 10

restrained by soft sales in overhead projectors and supplies,  market
softness  in  industrial  abrasives, and  was  hurt  by  declines  in
pharmaceuticals.

Cost  of  goods  sold,  which  includes manufacturing,  research  and
development, and engineering, was 56.6 percent of sales, down  eight-
tenths  of a percentage point from the second quarter last year,  and
down  seven-tenths of a percentage point from the first quarter  this
year.  Gross margins benefited from lower raw material costs and  the
company's restructuring actions.

In  the  second quarter of 1999, the company realized a net gain  for
one-time  pre-tax  items  of $104 million ($55  million  after  tax).
These  items  related to gains on the divestitures of two businesses,
net  of  an  investment valuation adjustment. This pre-tax  gain  was
recorded  as  a  reduction  of  selling, general  and  administrative
expenses.  The impact of this net gain on 3M's Consolidated Statement
of Income follows.

Selling,  general and administrative expenses were  22.6  percent  of
sales.  Excluding one-time items, this spending totaled 25.3  percent
of  sales,  down  three-tenths of a percentage point  from  the  same
quarter  last  year, and down two-tenths of a percentage  point  from
this year's first quarter.  This spending benefited from productivity
gains  stemming from restructuring actions, and by continued spending
discipline.

Worldwide operating income was 20.8 percent of sales.  Excluding one-
time  items,  operating income was 18.1 percent,  up  1.1  percentage
points  from  the  second quarter last year.  In  dollars,  operating
income, excluding one-time items, increased 9.0 percent from the same
quarter last year.

Second-quarter  interest expense of $26 million was down  $9  million
from  the  same quarter last year, reflecting lower debt levels.  Net
investment  and  other income was $7 million,  in  line  with  recent
quarters.


<PAGE> 11

Excluding one-time items, the worldwide effective income tax rate for
the  quarter was 35.5 percent, the same as in the second quarter last
year.  Including one-time items, the total 3M combined effective  tax
rate was 37.0 percent for the second quarter of 1999.

Net  income  for the second quarter of 1999 totaled $476 million,  or
$1.17  per diluted share.  Excluding 1999 one-time items, net  income
totaled $421 million, or $1.03 per diluted share, compared with  $386
million,  or $.94 per diluted share, in the second quarter  of  1998.
The  company  estimates that changes in the value of the U.S.  dollar
decreased  earnings  for  the quarter by  about  2  cents  per  share
compared with the second quarter of 1998.  This estimate includes the
effect  of  translating  profits  from  local  currencies  into  U.S.
dollars; the impact of currency fluctuations on the transfer of goods
between   3M  operations  in  the  United  States  and  abroad;   and
transaction gains and losses.

Year-to-date
Worldwide  sales  for  the first six months of  1999  totaled  $7.639
billion,  up  2.3  percent from the same period  last  year.   Volume
increased  about  3 percent, while selling prices were  up  slightly.
Currency translation reduced worldwide sales by about 1 percent.

In  the  United  States, sales increased about 2  percent  to  $3.621
billion,  driven by volume increases. Internationally, sales  totaled
$4.018  billion.   Volume  abroad increased about  3  percent,  while
selling  prices were up about 2 percent, resulting in overall  local-
currency sales gains of about 5 percent. Currency translation reduced
international sales by about 2 percent.

Cost  of  goods  sold,  which  includes manufacturing,  research  and
development,  and  engineering,  was  56.9  percent  of  sales,  down
slightly  from  the  first six months of last  year.   Gross  margins
benefited   from   lower  raw  material  costs  and   the   company's
restructuring actions.

As  discussed  earlier, in the second quarter  of  1999  the  company
realized  a net gain for one-time items of $104 million ($55  million
after  tax).   The  impact  of  this net gain  on  3M's  Consolidated
Statement of Income follows.

</TABLE>

Selling,  general and administrative expenses were  24.1  percent  of
sales.  Excluding one-time items, this spending totaled 25.4  percent
of sales, up slightly from the same period last year.

Worldwide operating income was 19.0 percent of sales.  Excluding one-
time  items, operating income was 17.7 percent, the same  as  in  the
first  six  months last year. In dollars, operating income, excluding
one-time items, increased 2.1 percent from the same period last year.

The  first  six months interest expense of $57 million was  down  $12
million from the same period last year, reflecting lower debt levels.
Net  investment and other income was $15 million, in line with recent
trends.

Excluding one-time items, the worldwide effective income tax rate for
the  first six months of 1999 was 35.7 percent, essentially unchanged
from  the same period last year.  Including one-time items, the total
3M  combined  effective tax rate was 36.6 percent for the  first  six
months of 1999.

Net income for the first six months of 1999 totaled $860 million,  or
$2.12  per diluted share.  Excluding 1999 one-time items, net  income
totaled $805 million, or $1.98 per diluted share, compared with  $786
million,  or $1.92 per diluted share, in the first half of 1998.  The
company  estimates  that  changes in the value  of  the  U.S.  dollar
decreased earnings for the first six months of 1999 by about 4  cents
per share compared with the same period of 1998.

FUTURE OUTLOOK
The company encountered a difficult set of challenges in 1998 - large
negative   currency   effects,   economic   contractions   in    many
international  markets, and softness in a few key U.S.  markets.   To
improve productivity and reduce costs, the company is exiting certain
product   lines,   consolidating   manufacturing   operations,    and
eliminating  lower-value activities in corporate  service  functions.
Relating  to  these  actions, the company  recorded  a  restructuring
charge  in the second half of 1998. This charge is discussed  in  the
1998 Form 10-K.


<PAGE> 13

The company announced in mid-1998, as part of its restructuring plan,
its  intent to reduce about 4,500 positions by December 31, 1999.  As
of  July 29, 1999, employment has declined approximately 5,000 people
due to both the restructuring and attrition.

When fully implemented by the end of 1999, the restructuring plan  is
expected to provide annual pre-tax savings of about $250 million. The
company   anticipates  implementation  costs  associated  with   this
restructuring plan to be about $35 million in 1999. These costs,  not
included  in  the  1998  restructuring charge, include  expenses  for
relocating  employees, inventory and equipment; unfavorable  overhead
variances;  and  other  expenses. If the company  does  not  generate
adequate  sales growth, normal increases in salaries  and  wages  and
additional depreciation from capital expenditures will create offsets
to the annual savings.

In  the  second  half  of  1999,  the  company  expects  to  increase
international sales in local currencies about 7 to 8 percent. In  the
Asia Pacific area, the company expects to register double-digit local-
currency sales gains, driven by demand for new 3M products and
by  gradually  improving  Asian economies.  In  Europe,  the  company
expects  a  slight  acceleration  in  growth,  with  sales  in  local
currencies  increasing about 4 to 5 percent. In Latin America,  sales
in  local currencies are expected to increase at a double-digit  rate
in  the second half of the year.  Sales are expected to grow 3  to  4
percent in the United States.

The company is not able to project what the consequences will be from
the  dynamic  economies around the world. The company  is  monitoring
business  conditions closely and is prepared to make  adjustments  in
costs, pricing and investments as appropriate.

Based  on  currency rates as of July 29, 1999, the company  estimates
that  currency would negatively impact second half earnings  by  less
than 5 cents per share.

Capital  spending totaled $1.430 billion in 1998, and is expected  to
total  $1.1 billion for 1999.  Excluding one-time items, the  company
does not expect a significant change in its tax rate in 1999.

YEAR 2000 READINESS
The  Year 2000 issue is the result of using only the last two  digits
to  indicate the year in computer hardware and software programs  and
embedded  technology such as micro-controllers. As  a  result,  these
programs  do  not  properly recognize a year that  begins  with  "20"
instead of the familiar "19."  If uncorrected, such programs will  be
unable  to  interpret dates beyond the year 1999, which  could  cause
computer  system  failure or other errors disrupting normal  business
operations.


<PAGE> 14

The  company recognizes the importance of readiness for the Year 2000
and  has  given  it  high priority.  In November  1996,  the  company
created  a  corporate-wide Year 2000 project  team  representing  all
company business and staff units.  The team's objective is to  ensure
an  uninterrupted  transition to the year 2000 by assessing,  testing
and  modifying  IT  and  non-IT systems  (defined  below)  and  date-
sensitive company products so that (a) they will perform as intended,
regardless of the date (before, during and after December 31,  1999),
and  (b)  dates  (before,  during and after  December  31,  1999  and
including  February 29, 2000) can be processed with expected  results
("Year 2000 Compliant"). The scope of the Year 2000 compliance effort
includes  (i)  information technology ("IT")  such  as  software  and
hardware;  (ii) non-IT systems or embedded technology such as  micro-
controllers   contained  in  various  manufacturing  and   laboratory
equipment;   environmental  and  safety   systems,   facilities   and
utilities,  (iii)  date-sensitive  company  products;  and  (iv)  the
readiness  of  key third parties, including suppliers and  customers,
with whom the company has material business relationships.

The  Year  2000 project team has taken an inventory of IT and  non-IT
systems and date-sensitive company products that might malfunction or
fail  as  a result of using only the last two digits to indicate  the
year. The project teams then categorized the potential date component
failures into three categories: "Vital" (stops the business operation
and no short-term solution is available); "Critical" (inconvenient to
the  business operation and a short-term solution is available);  and
"Marginal" (inconsequential to the business operation).

IT  Systems  -  The  company  is using  both  internal  and  external
resources  to  remediate and test millions of  lines  of  application
software  code. As of June 30, 1999, approximately (i) 98 percent  of
the  core  central  IT  application systems  (e.g.,  general  ledger,
payroll,  procurement  and  order management),  (ii)  95  percent  of
central   IT   infrastructure   systems  (e.g.,   telecommunications,
electronic  mail, databases, data centers, and system software),  and
(iii)  94 percent of the other IT systems (e.g., systems that support
business  and staff organizations) located in the United States  that
are  deemed  "Vital"  or  "Critical" are believed  to  be  Year  2000
Compliant. As of June 30, 1999, approximately 99 percent  of  the  IT
systems  in  subsidiaries outside the United States that  are  deemed
"Vital" or "Critical" are believed to be Year 2000 Compliant.

Non-IT  Systems  -  The company has more than 100  manufacturing  and
laboratory locations worldwide with varying degrees of non-IT systems
(such  as  programmable  logic  controllers,  gauging  guidance   and
adjustment systems and testing equipment). Assessment and testing  of
non-IT  systems  for  Year  2000  compliance  has  proven  much  more
difficult than assessing compliance of IT systems because testing  of
non-IT   systems   often  requires  shutdown  of  the   manufacturing
operations.


<PAGE> 15

As a result, the company has approached assessment and testing of non-
IT systems that are common to many of the company's facilities by (i)
contacting  the  suppliers  of  these non-IT  systems  and  obtaining
statements that the systems are Year 2000 Compliant, and (ii) testing
components  of  non-IT  systems when they are shut  down  for  normal
maintenance.  The company has also shut down manufacturing  lines  in
three of its facilities and tested non-IT systems that are common  to
many  of the company's facilities. These tests demonstrate that "time
intervals"  instead of "dates" are used almost exclusively  in  these
non-IT  systems  and  support  the company's  belief  that  potential
disruptions  of  such systems due to the Year 2000  issue  should  be
minimal.

As  of  June 30, 1999, approximately 96 percent of the non-IT systems
located  in  the United States that are deemed "Vital" or  "Critical"
and  approximately 99 percent of the non-IT systems  in  subsidiaries
outside  the United States that are deemed "Vital" or "Critical"  are
believed to be Year 2000 Compliant.

Company  Products - The vast majority of the company's  products  are
not  date-sensitive. The company has collected information on current
and  discontinued  date-sensitive products.   The  company's  website
(http://www.3M.com)  contains a section  dedicated  to  communicating
year  2000  information  to its customers. This  website  includes  a
search  feature to enable customers to determine whether  certain  3M
products are Year 2000 compliant.

Material  Third  Party Relationships - In addition to  internal  Year
2000  IT and non-IT remediation activities, the company is in contact
with  key  suppliers, contract manufacturers and electronic  commerce
customers  to  minimize potential disruptions  in  the  relationships
between the company and these important third parties related to  the
Year  2000 issue. The assessment process includes (i) initial survey,
(ii)  risk  assessment and contingency planning, and (iii)  follow-up
reviews.

The company has also categorized supplies purchased from vendors into
three  categories: "Vital" (disruption of supply stops  the  business
operation  and  no  short-term  solution  is  available);  "Critical"
(disruption of supply is inconvenient to the business operation and a
short-term  solution  is  available); and "Marginal"  (disruption  of
supply is inconsequential to the business operation). The company has
focused  its  efforts on those vendors that supply goods or  services
deemed  "Vital" to the company's business. The company  has  received
responses to its initial year 2000 readiness survey from most of  its
Vital suppliers indicating that the suppliers are working on the year
2000  issue. While the company cannot guarantee compliance  by  third
parties,  the  company has developed contingency plans with  its  key
suppliers  that includes the availability of appropriate  inventories
of supplies in the event the supplier is not Year 2000 Compliant.


<PAGE> 16

As  with suppliers, the readiness of customers to deal with year 2000
issues may affect their operations and their ability to order and pay
for  products.  Certain business units of the company  have  surveyed
their  major  direct  customers about their year  2000  readiness  in
critical areas of their operations. The responses have been generally
positive in favor of readiness. The company cannot determine at  this
time  how  year  2000 issues may affect customer order  patterns.  As
customers prepare their businesses for the year 2000, they may either
delay  or  accelerate purchases of products from the company.   As  a
result,  changes  in customer order patterns in preparation  for  the
year  2000  may  affect  the company's future  revenues  and  revenue
patterns.  At this time, the company believes the greatest likelihood
of  accelerated purchases of products is in the Health Care  segment.
In  other segments, early indications are that most customers are not
building inventories in anticipation of the year 2000.

Risks  and Worst Case Scenarios - The company believes that its  most
reasonably likely worst case scenarios regarding the year 2000  issue
involve the IT and non-IT systems of third parties rather than the IT
and  non-IT systems and products of the company. Because the  company
has  far  less  control  over assessing the year  2000  readiness  of
certain  third parties, the company believes the risks  are  greatest
with  suppliers of electrical, telecommunications, and transportation
services, particularly suppliers of such services located outside the
United  States.  Contingency planning regarding the failure  of  such
services  involves  maintaining appropriate inventories  of  key  raw
materials and products.

Contingency  Planning  - The company is preparing  contingency  plans
specifying what the company will do if failures occur in IT and  non-
IT  systems, or important third parties are not Year 2000  Compliant.
The  process  includes identifying and prioritizing risks,  assessing
the business impact of those risks, creating notification procedures,
and  preparing written contingency plans for those failures with  the
greatest  risk  to  the company. As of June 30, 1999,  the  company's
contingency plans were 90% complete for its IT and non-IT systems and
other high risk areas and 100% complete for its key suppliers.

Costs  -  Since inception of the company's efforts on the  year  2000
issue through June 30, 1999, the company had spent approximately  $60
million  out of a total estimate of $76 million related to  the  Year
2000  readiness  issue. These costs include the  costs  incurred  for
external  consultants and professional advisors  and  the  costs  for
software  and  hardware. The company's process for tracking  internal
costs  does  not capture all of the costs incurred for  each  of  the
teams  working  on  the Year 2000 project. Such  internal  costs  are
principally  the  related payroll costs for its  information  systems
group  and  other  employees working on the Year  2000  project.  The
company  is expensing as incurred all costs related to the assessment
and  remediation of the Year 2000 issue. These costs are being funded
through operating cash flows.


<PAGE> 17

The  company's current estimates of the time and costs  necessary  to
remediate  and test its computer systems are based on the  facts  and
circumstances  existing at this time. The estimates were  made  using
assumptions of future events, including the continued availability of
certain  resources,  such as skilled IT personnel and  infrastructure
(e.g.,    electrical   supply   and   water   and   sewer   service);
telecommunications, transportation supply chains, critical  suppliers
of  materials;  and  Year 2000 modification plans and  implementation
success  by  key  third-parties.  New developments could  affect  the
company's estimates of the amount of time and costs needed to  modify
and  test  its  IT  and non-IT systems for Year 2000 compliance  and,
depending on the year 2000 readiness of certain third parties,  could
affect   the  company's  ability  to  conduct  its  business.   These
developments  include, but are not limited to: (i)  the  availability
and  cost  of  personnel trained in this area; (ii)  the  ability  to
locate  and correct all relevant date-sensitive code in both  IT  and
non-IT  systems;  (iii)  unanticipated  failures  in  IT  and  non-IT
systems; (iv) the planning and Year 2000 compliance success that  key
customers   and  suppliers  attain;  (v)  failure  or   collapse   of
infrastructure (e.g., disruptions of electrical supply and water  and
sewer service), telecommunications, transportation supply chains, and
critical suppliers of materials, particularly those suppliers of such
services  and  goods  located outside the  United  States;  and  (vi)
unforeseen  product  shortages  due  to  hoarding  of  critical   raw
materials.

The   company   cannot  determine  the  impact  of  these   potential
developments on the current estimate of probable costs of making  its
products  and  IT  and  non-IT systems Year  2000  Compliant  or  the
financial impact on the company. Accordingly, the company is not able
to  estimate possible future costs beyond the current estimates.   As
new  developments  occur,  these cost estimates  may  be  revised  to
reflect  the impact of these developments on the costs to the company
of making its products and IT and non-IT systems Year 2000 Compliant.
Such  cost  revisions  could have a material adverse  impact  on  the
company's  net  income  in the quarterly period  in  which  they  are
recorded.  Although the company considers it unlikely, such revisions
could  also  have  a  material  adverse effect  on  the  consolidated
financial position or annual results of operations of the company.

Various of the company's disclosures and announcements concerning its
products and year 2000 programs are intended to constitute "Year 2000
Readiness  Disclosures" as defined in the recently enacted Year  2000
Information  and  Readiness Disclosure Act. The  Act  provides  added
protection  from liability for certain public and private  statements
concerning  an  entity's  year  2000  readiness  and  the  year  2000
readiness  of  its  products and services. The Act  also  potentially
provides  added protection from liability for certain types  of  year
2000  disclosures made after January 1, 1996 and before the  date  of
enactment of the Act.

THE EURO CONVERSION
On  January  1, 1999, 11 of the 15 member countries of  the  European
Union  (EU)  established fixed conversion rates through the  European
Central  Bank (ECB) between existing local currencies and  the  euro,
the EU's new single currency.  The participating countries had agreed
to  adopt the euro as their common legal currency on that date.  From
that  date,  the  euro  has  been traded on  currency  exchanges  and
available for non-cash transactions.

Following  introduction  of the euro, local  currencies  will  remain
legal tender until December 31, 2001.  During this transition period,
goods  and  services  may be paid for with  the  euro  or  the  local
currency under the EU's "no compulsion, no prohibition" principle. If
cross-border  payments  are  made in a  local  currency  during  this
transition period, the amount will be converted into euros  and  then
converted from euros into the second local currency at rates fixed by
the  ECB. The participating countries will issue new euro-denominated
bills  and  coins for use in cash transactions at about December  31,
2001.   By  no later than July 1, 2002, participating countries  will
withdraw all bills and coins denominated in local currencies,  making
the euro conversion complete.

In February 1997, the company created a European Monetary Union (EMU)
Steering  Committee  and  project  teams  representing  all   company
business  and staff units in Europe.  The common objective  of  these
teams is to ensure a smooth transition to EMU for the company and its
constituencies.   The  scope  of  the  teams'  efforts  includes  (i)
assessing  the  euro's impact on the company's business  and  pricing
strategies  for customers and suppliers, and (ii) ensuring  that  the
company's business processes and information technology (IT)  systems
can  process  transactions in euros and local currencies  during  the
transition  period and achieve the conversion of all  relevant  local
currency  data to the euro by December 31, 2001, in the participating
countries.

The  European market contributed 26 percent of consolidated sales and
20   percent   of   consolidated  operating  income,  excluding   the
restructuring charge, in 1998. The participating countries  accounted
for 79 percent of the company's sales in the European market in 1998.
The  company  believes that the euro will, over time, increase  price
competition  for the company's products across Europe due  to  cross-
border price transparency. The company also believes that the adverse
effects of increased price competition will be offset somewhat by new
business opportunities and efficiencies. The company, however, is not
able  to  estimate the anticipated net long-term impact of  the  euro
introduction on the company.

The company has, in preparation for EMU, made significant investments
in  IT  systems  in Europe and these investments already  enable  the
company to manage customer orders, invoices, payments and accounts in
euros  and  in  local  currencies according to  customer  needs.  The
company anticipates spending approximately $35-50 million to complete
the  conversion  of  all  its IT systems in Europe  to  the  euro  by
December  31, 2001. The company is developing appropriate contingency
plans  in  order  that  the  euro adoption does  not  jeopardize  the
operations of the company.


<PAGE> 19

The  euro  introduction is not expected to have a material impact  on
the company's overall currency risk.  Although the company engages in
significant  trade within the EU, the impact to date  of  changes  in
currency exchange rates on trade within the EU has not been material.
The  company  anticipates  the euro will  simplify  financial  issues
related  to  cross-border trade in the EU and reduce the  transaction
costs  and  administrative time necessary to manage  this  trade  and
related risks.  The company believes that the associated savings will
not be material to corporate results.

The  company  has derivatives outstanding beyond June  30,  1999,  in
several  European  currencies.  Under the  EU's  "no  compulsion,  no
prohibition"  principle,  the outstanding derivative  positions  will
either  mature  as  local  currency  contracts  or  convert  to  euro
contracts at no additional economic cost to the company.  The company
believes  that  systems used to monitor derivative positions  can  be
appropriately modified for these changes.  The company  believes  the
impact of the euro introduction on the company's derivative positions
will not be material.

FORWARD-LOOKING STATEMENTS
The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor"  for  certain  forward-looking  statements.   This  Quarterly
Report  on  Form  10-Q  contains  forward-looking  statements,  which
reflect the company's current views with respect to future events and
financial performance.

These  forward-looking statements are subject to  certain  risks  and
uncertainties,  including those identified here,  which  could  cause
actual results to differ materially from historical results or  those
anticipated.   The  words  "aim," "believe," "expect,"  "anticipate,"
"intend," "estimate," "will," "should," "could" and other expressions
that  indicate  future  events  and trends  identify  forward-looking
statements.

Actual   future  results  and  trends  may  differ  materially   from
historical  results or those anticipated depending on  a  variety  of
factors,  including, but not limited to:  foreign exchange rates  and
fluctuations  in  those  rates;  the  effects  of,  and  changes  in,
worldwide  economic conditions;  the timing and market acceptance  of
new   product  offerings;  raw  materials,  including  shortages  and
increases in the costs of key raw materials; the impact of  the  Year
2000   issue;  and  legal  proceedings  (see  discussion   of   Legal
Proceedings in Part II, Item 1 of this Form 10-Q).

FINANCIAL CONDITION AND LIQUIDITY
The  company's  financial  condition  and  liquidity  remain  strong.
Working capital increased $626 million to $2.558 billion at June  30,
1999,  compared with $1.932 billion at year-end 1998.  The  company's
key inventory index was 3.2 months, down from 3.4 months at year-end.
The  accounts receivable average days' sales outstanding was 59 days,
down slightly from year-end. The company's current ratio was 1.7,  up
from 1.4 at year-end.


<PAGE> 20

Total debt decreased $805 million from year-end 1998 to $2.301 billion.
As  of  June 30, 1999, total debt was 27 percent  of  total capital.

The company's strong credit rating provides ready and ample access to
funds  in  global capital markets. At June 30, 1999, the company  had
available short-term lines of credit totaling about $665 million.

Net  cash provided by operating activities totaled $1.713 billion  in
the  first  six  months of the year, up $946 million  from  the  same
period  last year.  The first six months of 1999 was helped  by  good
working capital management.  Inventories declined about $450 million,
or  18 percent, compared to June 30, 1998.  Working capital and other
changes in 1999 include a $134 million use of cash for the impact  of
employee  termination benefits paid in connection with  restructuring
activities. Net cash inflows from mammary implant litigation were $57
million  in the first six months of 1999, compared with $185  million
in net cash outflows in the same period last year.

Timing differences between payment of implant liabilities and receipt
of related insurance recoveries could affect the cash flows of future
periods.  This is discussed in Part II, Item 1, Legal Proceedings, of
this Form 10-Q.

Cash  used in investing activities was $353 million in the first  six
months  of  the year, compared with $768 million in the  same  period
last year. Capital expenditures for the first six months of 1999 were
$513  million, a decrease of about 28 percent compared with the  same
period  last year.  The company received cash proceeds in the  second
quarter  of  1999  of  $203 million relating to its  divestitures  of
Eastern Heights Bank and the Cardiovascular Systems business.

Treasury stock repurchases for the first six months of 1999 were $223
million,  compared with repurchases in the same period last  year  of
$377  million. Financing activities in the first six months  of  1999
for both short-term and long-term debt included net cash outflows  of
$798  million, compared with net cash inflows of $583 million in  the
same period last year.

The  company repurchased about 2.6 million shares of common stock  in
the first six months of 1999, compared with 4.2 million shares in the
same  period  last  year.  In February 1999, the Board  of  Directors
authorized  the repurchase of up to 12 million shares  of  3M  common
stock  through December 31, 1999.  As of June 30, 1999,  9.6  million
shares  remained  authorized for repurchase.  Stock  repurchases  are
made to support employee stock purchase plans and for other corporate
purposes.

Cash dividends paid to shareholders totaled $452 million in the first
six  months  of  this year, compared with $445 million  in  the  same
period  last  year.   In  February 1999, the quarterly  dividend  was
increased to 56 cents a share.

Legal  proceedings are discussed in the Legal Proceedings section  in
Part II, Item 1, of this Form 10-Q.

      Minnesota Mining and Manufacturing Company and Subsidiaries
                      PART II.  Other Information

Item 1.  Legal Proceedings
The  company and certain of its subsidiaries are named as  defendants
in   a  number  of  actions,  governmental  proceedings  and  claims,
including  environmental  proceedings and products  liability  claims
involving  products  now or formerly manufactured  and  sold  by  the
company.   In  some actions, the claimants seek damages  as  well  as
other   relief,   which,  if  granted,  would   require   substantial
expenditures.  The  company  has accrued certain  liabilities,  which
represent reasonable estimates of its probable liabilities for  these
matters.   The company also has recorded receivables for the probable
amount of insurance recoverable with respect to these matters.

Some  of these matters raise difficult and complex factual and  legal
issues,  and  are subject to many uncertainties, including,  but  not
limited  to,  the facts and circumstances of each particular  action,
the  jurisdiction  and forum in which each action is  proceeding  and
differences in applicable law. Accordingly, the company is not always
able  to estimate the amount of its possible future liabilities  with
respect to such matters.

There  can be no certainty that the company may not ultimately  incur
charges,  whether  for governmental proceedings and claims,  products
liability  claims,  environmental proceedings or  other  actions,  in
excess  of presently established accruals.  While such future charges
could  have a material adverse impact on the company's net income  in
the quarterly period in which they are recorded, the company believes
that  such  additional charges, if any, would  not  have  a  material
adverse  effect  on  the consolidated financial  position  or  annual
results  of operations of the company.  (NOTE: The preceding sentence
applies  to  all legal proceedings involving the company  except  the
breast implant litigation, which is discussed separately in the  next
section).

Breast Implant Litigation

As of June 30, 1999, the company had been named as a defendant, often
with  multiple  co-defendants, in 4,631 lawsuits and  117  claims  in
various  courts,  all  seeking damages  for  personal  injuries  from
allegedly  defective  breast implants.   These  claims  and  lawsuits
purport  to  represent 18,054 individual claimants.  It  is  not  yet
certain  how  many  of  these lawsuits and  claims  involve  products
manufactured   and  sold  by  the  company,  as  opposed   to   other
manufacturers,  or  how  many of these lawsuits  and  claims  involve
individuals  who  accepted  benefits  under  the  Revised  Settlement
Program   (as   defined  later).  The  company  has  confirmed   that
approximately 850 of the above individual claimants have opted out of
the  class  action  and have 3M implants.  The  company  entered  the
business  of  manufacturing breast implants  in  1977  by  purchasing
McGhan  Medical Corporation.  In 1984, the company sold the  business
to a corporation that also was named McGhan Medical Corporation.


<PAGE> 22

The typical claim or lawsuit alleges the individual's breast implants
caused  one  or  more  of  a  wide  variety  of  ailments  and  local
complications, including, but not limited to, non-specific autoimmune
disease,  scleroderma,  lupus,  rheumatoid  arthritis,  fibromyalgia,
mixed connective tissue disease, Sjogren's Syndrome, dermatomyositis,
polymyositis and chronic fatigue.

Plaintiffs in these cases typically seek monetary damages,  often  in
unspecified  amounts, and also may seek certain  types  of  equitable
relief,  including requiring the company to fund the costs associated
with removal of the breast implants.

A  number  of  breast  implant claims and  lawsuits  seek  to  impose
liability on the company under various theories for personal injuries
allegedly  caused  by  breast  implants  manufactured  and  sold   by
manufacturers  other  than the company. These manufacturers  include,
but  are not limited to, McGhan Medical Corporation and manufacturers
that  are  no longer in business or that are insolvent, whose  breast
implants  may or may not have been used in conjunction with  implants
manufactured  and  sold  by the company.   These  claims  raise  many
difficult  and complex factual and legal issues that are  subject  to
many  uncertainties,  including the facts and circumstances  of  each
particular claim, the jurisdiction in which each suit is brought, and
differences in applicable law and insurance coverage.

A number of breast implant lawsuits seek to recover punitive damages.
Any  punitive damages that may be awarded against the company may  or
may  not  be covered by certain insurance policies depending  on  the
language of the insurance policy, applicable law and agreements  with
insurers.

In  addition to individual suits against the company, a class  action
on  behalf  of  all  women  with breast implants  filed  against  all
manufacturers  of such implants has been conditionally certified  and
is  pending  in  the United States District Court  for  the  Northern
District  of Alabama (the "Court")(DANTE, ET AL., V. DOW CORNING,  ET
AL.,  U.S.D.C., N. Dist., Ala., 92-2589; part of IN RE: SILICONE  GEL
BREAST IMPLANT PRODUCT LIABILITY LITIGATION, U.S.D.C., N. Dist. Ala.,
MDL  926,  U.S.D.C.,  N.  Dist. Ala., CV 92-P-10000-S;  now  held  in
abeyance  pending  settlement proceedings  in  the  settlement  class
action LINDSEY, ET AL., V. DOW CORNING CORPORATION, ET AL., U.S.D.C.,
N.  Dist., Ala., CV 94-P-11558-S). Class actions, some of which  have
been certified, are pending in various state courts, including, among
others,  Louisiana, Florida and Illinois, and in the British Columbia
courts  in Canada.  The Louisiana state court action (SPITZFADEN,  ET
AL.,  v.  DOW  CORNING  CORPORATION, ET AL.,  Dist.  Ct.,  Parish  of
Orleans,  92-2589)  has  been decertified by  the  trial  court.  The
Louisiana  Supreme Court has denied plaintiffs' writ for an emergency
appeal from the decertification. A normal appeal remains pending.


<PAGE> 23

The  company  also  has  been served with a  purported  class  action
brought on behalf of children allegedly exposed to silicone in  utero
and  through  breast  milk.   (FEUER, ET  AL.,  V.  MCGHAN,  ET  AL.,
U.S.D.C.,  E. Dist. NY, 93-0146.)  The suit names all breast  implant
manufacturers  as  defendants  and  seeks  to  establish  a  medical-
monitoring fund.

On  December  22,  1995, the Court approved a  revised  class  action
settlement  program  for  resolution of claims  seeking  damages  for
personal  injuries  from  allegedly defective  breast  implants  (the
"Revised Settlement Program").  The Revised Settlement Program  is  a
revision  of  a  previous settlement pursuant  to  a  Breast  Implant
Litigation Settlement Agreement (the "Settlement Agreement")  reached
on April 8, 1994, and approved by the Court on September 1, 1994.

The Court ordered that, beginning after November 30, 1995, members of
the  plaintiff  class  may  choose  to  participate  in  the  Revised
Settlement Program or opt out, which would then allow them to proceed
with separate products liability actions.

The  Revised Settlement Program includes domestic class members  with
implants  manufactured by certain manufacturer defendants,  including
Baxter  International, Bristol-Myers Squibb Company, the company  and
McGhan  Medical  Corporation.  The company's  obligations  under  the
Revised  Settlement  Program are limited to eligible  claimants  with
implants  manufactured  by  the  company  or  its  predecessors  ("3M
implants")  or manufactured only by McGhan Medical Corporation  after
its divestiture from the company on August 3, 1984 ("Post 8/84 McGhan
implants").   With  respect to claimants with only Post  8/84  McGhan
implants  (or  only  Post  8/84 McGhan implants  plus  certain  other
manufacturers'  implants), the benefits are  more  limited  than  for
claimants  with  3M implants. Post 8/84 McGhan implant  benefits  are
payable in fixed shares by the company, Union Carbide Corporation and
McGhan Medical Corporation.  McGhan Medical Corporation has defaulted
on  its fixed share obligation (which does not affect 3M's obligation
to  pay  its  share) and has a request for a mandatory  class  action
recently approved by the Court.

In  general, the amounts payable to individual current claimants  (as
defined  in the Court's order) under the Revised Settlement  Program,
and  the  company's  obligations to  make  those  payments,  are  not
affected by the number of class members who have elected to  opt  out
of  the  Revised  Settlement Program or the number of  class  members
making  claims under the Revised Settlement Program. In  addition  to
certain   miscellaneous  benefits,  the  Revised  Settlement  Program
provides for two compensation options for current claimants  with  3M
implants.

Under the first option, denominated as Fixed Amount Benefits, current
claimants  with 3M implants who satisfy disease criteria  established
in  the prior Settlement Agreement will receive amounts ranging  from
$5,000  to  $100,000,  depending on disease  severity  or  disability
level;  whether  the claimant can establish that  her  implants  have
ruptured; and whether the claimant also has had implants manufactured

by  Dow  Corning.  Under the second option, denominated as  Long-Term
Benefits,  current  claimants  with  3M  implants  who  satisfy  more
restrictive disease and severity criteria specified under the Revised
Settlement  Program  can  receive benefits ranging  from  $37,500  to
$250,000.

In  addition, current claimants with 3M implants are eligible for (a)
a  one-time payment of $3,000 upon removal of 3M implants during  the
course  of the class settlement, and (b) an advance payment of $5,000
against  the  above  referenced benefits  upon  proof  of  having  3M
implants and upon waiving or not timely exercising the right  to  opt
out  of the Revised Settlement Program.  Current claimants with  only
Post  8/84  McGhan implants (or only Post 8/84 McGhan  implants  plus
certain other manufacturers' implants) are eligible only for benefits
ranging from $10,000 to $50,000.

Eligible  participants  with 3M implants who  did  not  file  current
claims  but  are  able  to satisfy the more restrictive  disease  and
severity  criteria  during an ongoing period  of  15  years  will  be
eligible  for  the  Long-Term Benefits, subject  to  certain  funding
limitations.  Such participants also will be eligible for an  advance
payment  of $1,000 upon proof of having 3M implants and upon  waiving
or  not  timely  exercising  the right to  opt  out  of  the  Revised
Settlement  Program or, as an elective option expiring  on  June  15,
1999,  a  payment of $3,500 in full settlement of all breast  implant
claims  including any claim for Long-Term Benefits under the  Revised
Settlement Program.  Benefit levels for eligible participants who are
not  current  claimants and have only Post 8/84 McGhan  implants  (or
only  Post  8/84  McGhan implants plus certain  other  manufacturers'
implants) will range from $10,000 to $50,000.

On  June  10,  1998,  the Court approved the terms  of  a  settlement
program offered by Baxter International, Bristol-Myers Squibb Company
and  the company to eligible foreign implant recipients (the "Foreign
Settlement  Program").  Notices and claim forms were mailed  on  June
15,  1998.  Benefits to eligible foreign claimants range from  $3,500
to $50,000.

As   of   the  date  of  this  filing,  the  company  believes   that
approximately   90  percent  of  the  registrants,  including   those
claimants  who  filed current claims, have elected to participate  in
the  Revised  Settlement  Program. It is still  unknown  as  to  what
disease criteria all claimants have satisfied, and what options  they
have  chosen.   As  a  result, the total amount  and  timing  of  the
company's  prospective payments under the Revised Settlement  Program
cannot  be  determined with precision at this time. As  of  June  30,
1999,  the  company has paid $276 million into the court-administered
fund  as  a  reserve against costs of claims payable by  the  company
under   the  Revised  Settlement  Program  (including  a  $5  million
administrative  assessment). Additional  payments  will  be  made  as
necessary.  Payments to date have been consistent with the  company's
estimates of the total liability for these claims.


<PAGE> 25

In  the  first quarter of 1994, the company took a pre-tax charge  of
$35  million ($22 million after tax) in recognition of its then  best
estimate of its probable liabilities and associated expenses, net  of
the  probable amount of insurance recoverable from its carriers.   In
the second quarter of 1998, the company increased its estimate of the
minimum probable liabilities and associated expenses to approximately
$1.1  billion, with an offsetting increase in the probable amount  of
insurance  recoveries.  This  amount represents  the  company's  best
estimate of the minimum amount to cover the cost and expense  of  the
Revised Settlement Program and the cost and expense of resolving opt-
out  claims  and  recovering  insurance proceeds.  After  subtracting
payments of $1.063 billion as of June 30, 1999, for defense and other
costs  and settlements with litigants and claimants, the company  had
accrued liabilities of $37 million.

The  company  has  substantial primary and excess products  liability
occurrence  insurance  coverage  and claims-made  products  liability
insurance   coverage,   which  it  believes  provide   coverage   for
substantially  all of its current exposure for breast implant  claims
and  defense costs. Most insurers have alleged reservations of rights
to  deny all or part of the coverage for differing reasons, including
each  insurer's  obligations in relation to the other insurers  (i.e.
allocation) and which claims trigger both the various occurrence  and
claims-made insurance policies. Some insurers have resolved and paid,
or  committed to, their policy obligations. The company believes  the
failure  of many insurers to voluntarily perform as promised subjects
them  to  the  company's claims for excess liability and damages  for
breach of the insurers' obligation of good faith.

On  September  22,  1994, three excess coverage  occurrence  insurers
initiated  in  the  courts  of the State of Minnesota  a  declaratory
judgment  action against the company and numerous insurance  carriers
seeking adjudication of certain coverage issues and allocation  among
insurers.  On  December  9,  1994, the company  initiated  an  action
against  its occurrence insurers in the Texas State Court in and  for
Harrison County, seeking a determination of responsibility among  the
company's various occurrence insurers with applicable coverages.  The
state  of  Texas has the most implant claims.  This action has  since
been  removed to the U.S. District Court, Eastern District of  Texas,
and  stayed  pending resolution of the litigation  in  the  Minnesota
courts.

The  insurers that are parties to these actions generally acknowledge
that they issued products liability insurance to the company and that
breast  implant claims are products liability claims.  The  trial  in
Minnesota  to  resolve  the  company's  insurance  coverage  and  the
financial  responsibility of occurrence insurers for  breast  implant
claims and defense costs began on June 4, 1996, and is continuing  in
phases.  The most recent phase was completed on July 15, 1999.


<PAGE> 26

In  mid-October 1995, the occurrence insurers that are parties to the
litigation  in  Minnesota  filed more than  30  motions  for  summary
judgment  or  partial summary judgment. The insurers,  through  these
motions,  attempted  to shift all or a portion of the  responsibility
for  those  claims  the company believes fall within  the  period  of
occurrence-based  coverage (before 1986) into the period  of  claims-
made  coverage  (from  and after January 1, 1986).  The  trial  court
denied  the insurers' motions, ruling that the key issues of  trigger
and allocation raised in these motions would be resolved at trial. In
the  trial's  first  phase  in 1996, the  court  granted  3M  partial
declaratory  judgment on the question of when insurance  coverage  is
"triggered."  The court also granted the insurers' motion for partial
declaratory judgment on the question of the allocation method  to  be
applied  in the case. In July 1997, the trial court ruled further  on
the  trigger issue and on the general allocation method.  That ruling
was  consistent with and further supported the company's  opinion  as
stated   in   the  following  paragraph.   In  November  1997,   upon
reconsideration, the court reversed a portion of its July ruling  and
reinstated  a  portion of its previous ruling. The  company  believed
that  conflicting rulings existed that needed to be clarified by  the
court  and  reconciled with applicable law.  Motions to  clarify  the
allocation methodology of triggered policies under these rulings were
filed  and  have  been  ruled upon by the  Court.   While  the  Court
clarified  certain aspects of these rulings it also ruled that  there
would be no allocation from and after January 1, 1986. This ruling is
consistent with the company's position on the allocation issue.

The  company  believes it ultimately will prevail in  this  insurance
litigation.   The  company's belief is based on an  analysis  of  its
insurance  policies;  court decisions on these  and  similar  issues;
reimbursement by insurers for these types of claims; and consultation
with  outside counsel who are experts in insurance coverage  matters.
If,  however,  the  occurrence insurers ultimately  prevail  in  this
insurance  litigation, the company could be effectively  deprived  of
significant  and potentially material insurance coverage  for  breast
implant  claims.   (See  discussion of the  accrued  receivables  for
insurance recoveries below.)

As  of  June  30,  1999,  the  company had  accrued  receivables  for
insurance recoveries of $610 million, substantially all of  which  is
contested by the insurance carriers. During the first quarter of 1999
the  company executed a settlement agreement with its lead occurrence
underwriter.  Payments  of  settlement  dollars  of  this  and  other
agreements  were  received  in the second quarter  of  1999.  Various
factors could affect the timing and amount of proceeds to be received
under  the  company's various insurance policies, including  (i)  the
timing of payments made in settlement of claims; (ii) the outcome  of
occurrence  insurance  litigation in  the  courts  of  Minnesota  (as
discussed above) and Texas; (iii) potential arbitration with  claims-
made insurers; (iv) delays in payment by insurers; and (v) the extent
to which insurers may become insolvent in the future. There can be no
absolute assurance that the company will collect all amounts  accrued
as being probable of recovery from its insurers.


<PAGE> 27

The   company's   current  estimate  of  the  probable   liabilities,
associated expenses and probable insurance recoveries related to  the
breast  implant  claims  is  based on  the  facts  and  circumstances
existing  at this time. New developments may occur that could  affect
the company's estimates of probable liabilities (including associated
expenses)  and  the  probable amount of insurance recoveries.   These
developments include, but are not limited to, (i) the ultimate  Fixed
Amount  Benefit  distribution to claimants in the Revised  Settlement
Program;  (ii) the success of and costs to the company  in  defending
opt-out  claims,  including  claims  involving  breast  implants  not
manufactured  or  sold  by  the company; (iii)  the  outcome  of  the
occurrence insurance litigation in the courts of Minnesota and Texas;
and  (iv)  the  outcome  of  potential arbitration  with  claims-made
insurers.

The   company   cannot  determine  the  impact  of  these   potential
developments   on  the  current  estimate  of  probable   liabilities
(including associated expenses) and the probable amount of  insurance
recoveries.   Accordingly, the company is not able  to  estimate  its
possible  future  liabilities  and  recoveries  beyond  the   current
estimates  of  probable  amounts.  As new developments  occur,  these
estimates  may be revised, or additional charges may be necessary  to
reflect  the impact of these developments on the costs to the company
of   resolving  breast  implant  litigation,  claims  and   insurance
recoveries. Such revisions or additional future charges could have  a
material  adverse impact on the company's net income in the quarterly
period in which they are recorded. Although the company considers  it
unlikely, such revisions or additional future charges could also have
a  material adverse effect on the consolidated financial position  or
annual results of operations of the company.

The company conducts ongoing reviews, assisted by outside counsel, to
determine  the adequacy and extent of insurance coverage provided  by
its  occurrence and claims-made insurers. The company believes, based
on  these  ongoing  reviews and the bases  described  in  the  fourth
preceding  paragraph,  it is probable that the  collectible  coverage
provided by its applicable insurance policies is sufficient to  cover
substantially  all of its current exposure for breast implant  claims
and  defense  costs.   Based on the availability  of  this  insurance
coverage, the company believes that its uninsured financial  exposure
has   not  materially  changed  since  the  first  quarter  of  1994.
Therefore, no recognition of additional charges has been made.

Environmental Matters

The company also is involved in a number of environmental proceedings
by  governmental agencies and by private parties asserting  liability
for  past waste disposal and other alleged environmental damage.  The
company  conducts  ongoing investigations, assisted by  environmental
consultants, to determine accruals for the probable, estimable  costs
of  remediation.  The remediation accruals are reviewed each  quarter
and changes are made as appropriate.
