                 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. 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.

Pending Divestitures:
The company has entered into agreements to sell Eastern Heights Bank,
a   subsidiary  banking  operation,  to  Norwest  Bank  Minnesota  (a
subsidiary of Wells Fargo & Company), and to sell the assets  of  its
Cardiovascular  Systems  business to Terumo Corp.  of  Tokyo,  Japan.
These  divestitures,  expected to be finalized  late  in  the  second
quarter  or early in the third quarter of 1999, should generate  cash
proceeds (net of tax) of approximately $185 million.

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 quarter ended March 31, 1999, the company terminated  688
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 restructuring liability
as  of  March  31, 1999, totaled $198 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 periods ended March 31,  1999  and
1998.   MSOP options to purchase 11.2 million shares of common  stock
at  an  average price of $91.59, which were outstanding at March  31,
1999,  were  not included in the computation of diluted earnings  per
share because they would not have had a dilutive effect.

               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
March 31, 1999, and the related consolidated statements of income and
cash flows for the three-month periods ended March 31, 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
First Quarter
Worldwide sales for the first quarter totaled $3.776 billion, up  2.1
percent  from the first quarter last year.  Volume increased about  2
percent,  while  selling  prices were up about  1  percent.  Currency
translation  reduced  worldwide sales by about 1  percent.  Currency,
while  positive in the Asia Pacific area, was negative in other parts
of the world, especially Latin America.

In  the  United  States, sales increased about 2  percent  to  $1.768
billion,  driven by volume increases.  In Transportation, Safety  and
Specialty  Material Markets, U.S. volume increased about  4  percent.
Within  this  business segment, the company saw good  growth  in  its
commercial   graphics,  protective  materials  and  roofing   granule
businesses, and a pickup in demand for reflective products  following
a soft 1998.  In Industrial and Consumer Markets, led by the consumer
and  office businesses, volume increased nearly 3 percent. Demand for
certain  industrial products, including tapes and abrasives, remained
soft.  Volume  in  the U.S. health care businesses declined  about  3
percent  from the year-earlier quarter.  Sales of medical and  dental
products  experienced  good  growth,  but  sales  of  pharmaceuticals
declined due to the introduction of generic alternatives to a branded
3M  analgesic.  The largest effects of this competition  will  extend
through the third quarter of 1999.

Internationally,  sales  totaled  $2.008  billion.    Volume   abroad
increased  about 2.5 percent, while selling prices were  up  about  2
percent, resulting in overall local-currency sales gains of about 4.5
percent. Currency translation reduced international sales by about  2
percent. In Europe, volume increased less than 1 percent.  Sales were
impacted by economic slowing in Western Europe and by the uncertainty
in  developing  European countries.  Also, the company  is  comparing
against  its  strongest  quarter in Europe last  year.  In  the  Asia
Pacific  area,  volume increased about 7 percent, the company's  best
performance  in five quarters. In Japan, unit sales rose  5  percent,
despite continuing economic weakness.  In Asia outside Japan,  volume
rose about 12 percent. 3M experienced sharp volume rebounds in Korea,
Thailand  and  Indonesia, and good growth in the  China  region.   In
Latin  America, volume was roughly the same as in the  first  quarter
last  year.   While  unit sales increased more  than  10  percent  in
Mexico, volume was flat in Argentina and unit sales declined about  7
percent  in  Brazil.  The company increased selling prices  in  Latin
America  about  7  percent.  Currency  translation,  largely  due  to
Brazilian  devaluation,  reduced Latin American  sales  by  about  20
percent.  In Canada, volume increased more than 10 percent.

Worldwide,  the  Industrial and Consumer market sales  and  operating
income  growth  was  led  by  the  consumer  and  office  businesses.
Transportation,  Safety  and  Specialty  Material  segment  sales and


<PAGE> 10

operating  income  growth was led by films for laptop  computers  and
other  electronic displays, and by protective materials. Health  Care
showed good growth in medical and dental, but was hurt by declines in
pharmaceuticals.

Cost  of  goods  sold,  which  includes manufacturing,  research  and
development,  and engineering, was 57.3 percent of sales,  up  seven-
tenths  of  a  percentage  point from the first  quarter  last  year.
However, this was down more than 2 percentage points from the  fourth
quarter  and was an improvement of more than half a percentage  point
from  the  rate  the  company averaged for 1998 as  a  whole.   Gross
margins  benefited  from lower raw material costs and  the  company's
restructuring actions.

Selling,  general  and administrative spending was  25.5  percent  of
sales, higher than the company's target.  For the full year 1999, the
company expects this spending to be below 25 percent of sales, helped
by  productivity  gains stemming from restructuring actions,  and  by
continuing spending discipline.

Worldwide  operating  income  was 17.2 percent  of  sales,  down  1.2
percentage points from the first quarter last year.  While lower than
the  first  quarter last year, this represented an  improvement  from
each  of the past three quarters and from 1998 in total.  In dollars,
operating  income  declined 4.4 percent from the  same  quarter  last
year.

First  quarter  interest expense of $31 million was down  $3  million
from the same quarter last year.  Net investment and other income was
$8 million, in line with recent trends.

The  worldwide  effective income tax rate for the  quarter  was  36.0
percent, the same as in the first quarter last year.

Net  income totaled $384 million, or $.95 per diluted share, compared
with $400 million, or $.98 per diluted share, in the first 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 first 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.

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 1998. This charge is discussed in the 1998 Form 10-K.


<PAGE> 11

The company announced in mid-1998, as part of its restructuring plan,
its intent to reduce about 4,500 positions by December 31, 1999.  The
majority  of  these  reductions are expected by September  30,  1999.
During  the  quarter, employment declined approximately 1,100  people
due  to  both  the  restructuring and attrition, bringing  the  total
reductions  thus  far  to 3,500 people.  These reductions  have  been
about equally divided between U.S. and international operations.

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.

3M  expects  sales  growth  in  1999 of  4  to  5  percent  in  local
currencies. Sales are expected to grow 3 to 4 percent in  the  United
States.   Sales  growth in the U.S. is expected to  pick  up  in  the
remaining  three quarters of this year. Internationally, the  company
is  expecting to increase sales in local currencies 5 to  6  percent.
The  company expects continuing reasonable volume growth in the  Asia
region.  Asia appears to be slowly recovering and the company will be
comparing  against quarters last year when many Asian economies  were
at  their  low points. In Japan, the company is not counting  on  any
economic  improvement, but expects to continue to do reasonably  well
because of continuing demand for certain proprietary 3M products.  In
Latin America, the volume picture is expected to improve as the  year
progresses.  Latin America is expected to show continuing good growth
in Mexico, along with gradual improvement in Brazil and Argentina. In
Europe, comparisons will become easier in the coming quarters.  While
European economies are growing slowly, 3M anticipates slightly better
growth than in the first quarter.

The company is not able to project what the consequences will be from
the  turmoil  in various 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  at the end of  April  1999,  the  company
estimates that currency would reduce international sales for the year
by  about 3 percent and would negatively impact earnings per share by
8 cents for the full year.

Capital  spending totaled $1.430 billion in 1998, and is expected  to
be  in line with the company's target of $1.2 billion for 1999.   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.

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,
and  the  electronic  data interchange (EDI)  with  those  key  third
parties.

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 March 31, 1999, approximately (i) 98 percent  of
the  core  central  IT  application systems  (e.g.,  general  ledger,
payroll,  procurement  and  order management),  (ii)  92  percent  of
central   IT   infrastructure   systems  (e.g.,   telecommunications,
electronic  mail, databases, data centers, and system software),  and
(iii)  84 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 March 31, 1999, approximately 98 percent of  the  IT
systems  in  subsidiaries outside the United States that  are  deemed
"Vital" or "Critical" are believed to be Year 2000 Compliant.


<PAGE> 13

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.

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 March 31, 1999, approximately 93 percent of the non-IT systems
located  in  the United States that are deemed "Vital" or  "Critical"
and  approximately 97 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.

Third  Parties  -  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


<PAGE> 14

"Vital" suppliers indicating that the suppliers are working on the
year 2000 issue. While the company cannot guarantee compliance by third
parties,  the  company is developing contingency plans with  its  key
suppliers  that include  the availability of appropriate  inventories
of supplies in the event the supplier is not Year 2000 Compliant.

Risks  and Worst Case Scenarios - The company believes that its  most
reasonably likely worst case scenarios regarding the year 2000  issue
involves  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 March 31, 1999,  the  company's
contingency plans were 75% complete for its IT and non-IT systems and
100% complete for its key suppliers.

Costs  -  Through March 31, 1999, the company had spent approximately
$55  million out of a total estimate of $77 million related  to  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.

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


<PAGE> 15

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; (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 is traded on currency exchanges and is 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


<PAGE> 16

the  ECB.  By  no  later  than December 31, 2001,  the  participating
countries will issue new euro-denominated bills and coins for use  in
cash  transactions.   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% of consolidated sales and 20%  of
consolidated operating income, excluding the restructuring charge, 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  consolidated IT operations  and  made  significant
investments in IT systems in Europe in anticipation of the EMU.   The
company  expects that these investments will enable  the  company  to
manage customer orders, invoices, payments and accounts in euros  and
in local currencies according to customer needs during the three-year
transition  period.  During  this  period,  the  company  anticipates
spending  approximately $35-50 million to complete the conversion  to
the  euro. Because the company believes its IT systems will be  ready
by  December  31, 2001 for the euro conversion, it has not  developed
contingency plans at this time.

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 January 1,  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


<PAGE> 17

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 $142 million to $2.074 billion at March 31,
1999,  compared with $1.932 billion at year-end 1998.   The  accounts
receivable average days' sales outstanding was 60 days, down slightly
from  year-end.   The company's key inventory index was  3.3  months,
down  from  3.4 months at year-end.  The company's current ratio  was
1.5, up from 1.4 at year-end.

Total  debt  decreased  $386 million from  year-end  1998  to  $2.720
billion.  As  of March 31, 1999, total debt was 31 percent  of  total
capital.

The company's strong credit rating provides ready and ample access to
funds  in global capital markets. At March 31, 1999, the company  had
available short-term lines of credit totaling about $670 million.

Net cash provided by operating activities totaled $828 million in the
first  three months of the year, up $453 million from the same period
last  year.   The  first quarter of 1999 was helped by  good  working
capital  management.  Inventories declined by about $390 million,  or
16  percent,  when compared to the first quarter of  1998.    Working
capital  and  other  changes  in  1999 include a $65 million  use  of
cash for the


<PAGE> 18

impact   of   the   employee termination benefits paid in  connection
with the restructuring charge. Net cash outflows from mammary implant
litigation were $61 million lower than in the same period last  year.
During the second quarter of 1999, the company expects to receive more
than $200 million of insurance recoveries related to product claims.

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 $329 million in the first three
months  of  the year, compared with $401 million in the  same  period
last  year. Capital expenditures for the first three months  of  1999
were  $289 million, a decrease of about 15 percent when compared with
the  same  period  last year.  The company expects  to  receive  cash
proceeds  (net  of  tax) in the second or third quarter  of  1999  of
approximately  $185 million relating to its pending  divestitures  of
Eastern Heights Bank and the Cardiovascular Systems business.

Treasury  stock repurchases for the first three months of  1999  were
$32  million, compared with repurchases in the same period last  year
of  $187 million. Financing activities for both short-term and  long-
term  debt provided net cash outflows of $240 million, compared  with
net cash inflows of $258 million in the first three months last year.

The  company repurchased about 400,000 shares of common stock in  the
first  three months of 1999, compared with 2.2 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 March 31, 1999, 11.6 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 $225 million in the first
three  months of this year, compared with $222 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.  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.  See  discussion of breast implant  litigation  in  Legal
Proceedings, Part II, Item 1.)

      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  March  31, 1999, the company had been named as  a  defendant,
often  with multiple co-defendants, in 5,488 lawsuits and 121  claims
in  various  courts, all seeking damages for personal  injuries  from
allegedly  defective  breast implants.   These  claims  and  lawsuits
purport  to  represent 20,060 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  below).  The  company  has  confirmed   that
approximately  1,000 individuals who opted out of  the  class  action
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> 20

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.
Plaintiffs' writ for an emergency appeal from the decertification has
been  denied by the Louisiana Supreme Court. A normal appeal  remains
pending.


<PAGE> 21

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


<PAGE> 22

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% 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 March 31, 1999, the  company  has
paid  $232  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> 23

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  $1.007 billion as of March 31, 1999,  for  defense  and
other costs and settlements with litigants and claimants, the company
had accrued liabilities of $93 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 phases were completed on January  20,  1999
and March 31, 1999.


<PAGE> 24

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 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 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  March  31,  1999,  the company had  accrued  receivables  for
insurance recoveries of $750 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. The first payment of settlement dollars was received  on
April  14,  1999, with additional and final payments to  be  made  no
later than June 15, 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> 25

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.
