                  NOTES TO FINANCIAL STATEMENTS

                           (Unaudited)

The  financial statements include, in the opinion of  management,

all  adjustments necessary for a fair presentation of the results

of  operations and financial condition of Dean Witter Cornerstone

Fund  IV  (the  "Partnership").   The  financial  statements  and

condensed  notes  herein should be read in conjunction  with  the

Partnership's December 31, 1998 Annual Report on Form 10-K.



1.  Organization. Dean Witter Cornerstone Fund IV  is  a  limited

partnership  organized  to engage in the speculative  trading  of

futures  contracts  and forward contracts on  foreign  currencies

(collectively, "futures interests").  The Partnership is  one  of

the  Dean  Witter  Cornerstone Funds, comprised  of  Dean  Witter

Cornerstone  Fund II, Dean Witter Cornerstone Fund III,  and  the

Partnership.   The  Partnership's  general  partner  is   Demeter

Management  Corporation ("Demeter").  The non-clearing  commodity

broker  is  Dean Witter Reynolds Inc. ("DWR") and an unaffiliated

clearing  commodity broker, Carr Futures Inc. ("Carr"),  provides

clearing and execution services.  Both Demeter and DWR are wholly-

owned  subsidiaries of Morgan Stanley Dean Witter & Co. ("MSDW").

The  trading  advisors to the Partnership are  John  W.  Henry  &

Company, Inc. and Sunrise Capital Management, Inc. (collectively,

the "Trading Advisors").

           NOTES TO FINANCIAL STATEMENTS - (CONTINUED)


2. Related Party Transactions

The Partnership's cash is on deposit with DWR and Carr in futures

interests trading accounts to meet margin requirements as needed.

DWR  pays  interest on these funds based on current 13-week  U.S.

Treasury  bill rates. The Partnership pays brokerage  commissions

to DWR.

                                

3.  Financial Instruments

The  Partnership trades futures and forward contracts on  foreign

currencies.   Risk  arises from changes in  the  value  of  these

contracts  and  the  potential  inability  of  counterparties  to

perform  under  the terms of the contracts.  There  are  numerous

factors  which  may significantly influence the market  value  of

these contracts, including interest rate volatility.



In  June  1998, the Financial Accounting Standards  Board  issued

Statement  of  Financial Accounting Standard  ("SFAS")  No.  133,

"Accounting  for  Derivative Instruments and Hedging  Activities"

effective  for fiscal years beginning after June 15,  1999.   The

Partnership has elected to adopt the provisions of SFAS  No.  133

beginning with the fiscal year ended December 31, 1998.  SFAS No.

133  supersedes  SFAS  No. 119 and No. 105,  which  required  the

disclosure of average aggregate fair values and contract/notional





<PAGE>

                 DEAN WITTER CORNERSTONE FUND IV
           NOTES TO FINANCIAL STATEMENTS - (CONTINUED)




values, respectively, of derivative financial instruments for  an

entity  which carries its assets at fair value.  The  application

of  SFAS  No.  133  does  not have a significant  effect  on  the

Partnership's financial statements.



The net unrealized gain (loss) on open contracts is reported as a

component  of  "Equity in futures interests trading accounts"  on

the  Statements of Financial Condition and totaled $1,726,693 and

$(2,827,252)   at   March  31,  1999  and  December   31,   1998,

respectively.



Of  the $1,726,693 net unrealized gain on open contracts at March

31,  1999,  all  related to off-exchange-traded forward  currency

contracts.



Of  the  $(2,827,252) net unrealized loss on  open  contracts  at

December  31,  1998,  all related to off-exchange-traded  forward

currency contracts.



Off-exchange-traded  forward  currency  contracts  held  by   the

Partnership  at  March  31,  1999 and December  31,  1998  mature

through June 1999 and March 1999, respectively.





<PAGE>

                 DEAN WITTER CORNERSTONE FUND IV
           NOTES TO FINANCIAL STATEMENTS - (CONTINUED)




The  Partnership  is subject to the credit risk  associated  with

counterparty  non-performance.  The credit risk  associated  with

the  instruments in which the Partnership is involved is  limited

to  the  amounts  reflected  in the Partnership's  Statements  of

Financial  Condition.  DWR and Carr act as the futures commission

merchants  or  the counterparties with respect  to  most  of  the

Partnership's  assets.  Exchange-traded  futures  contracts   are

marked  to  market  on  a daily basis, with variations  in  value

settled  on  a  daily basis. Each of DWR and Carr, as  a  futures

commission  merchant for all of the Partnership's exchange-traded

futures contracts, are required, pursuant to regulations  of  the

Commodity  Futures Trading Commission ("CFTC") to segregate  from

their  own  assets, and for the sole benefit of  their  commodity

customers, all funds held by them with respect to exchange-traded

futures   contracts,  including  an  amount  equal  to  the   net

unrealized  gain on all open futures contracts, which  funds,  in

the aggregate, totaled $113,741,942 and $119,800,551 at March 31,

1999 and December 31, 1998, respectively.



With  respect  to  the Partnership's off-exchange-traded  forward

currency  contracts, there are no daily settlements of variations

in value nor is there any requirement that an amount equal to the

                 DEAN WITTER CORNERSTONE FUND IV
           NOTES TO FINANCIAL STATEMENTS - (CONCLUDED)




net  unrealized  gain  on open forward contracts  be  segregated.

With   respect  to  those  off-exchange-traded  forward  currency

contracts, the Partnership is at risk to the ability of Carr, the

sole  counterparty on all of such contracts, to perform.   Carr's

parent,   Credit  Agricole  Indosuez,  has  guaranteed   to   the

Partnership  payment  of  the  net  liquidating  value   of   the

transactions  in  the Partnership's account with Carr  (including

foreign currency contracts).


































<PAGE>
Item   2.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Liquidity -  Assets of the Partnership are deposited with DWR  as

non-clearing  broker  and  Carr as clearing  broker  in  separate

futures interest trading accounts. Such assets are held in either

non-interest bearing bank accounts or in securities  approved  by

the  CFTC  for  investment of customer funds.  The  Partnership's

assets held by DWR and Carr may be used as margin solely for  the

Partnership's trading.  Since the Partnership's sole  purpose  is

to   trade  in  futures  interests,  it  is  expected  that   the

Partnership  will continue to own such liquid assets  for  margin

purposes.

      The Partnership's investment in futures interests may, from

time  to time, be illiquid.  Most United States futures exchanges

limit  fluctuations in certain futures interest prices  during  a

single   day   by  regulations  referred  to  as   "daily   price

fluctuations  limits"  or  "daily  limits".   Pursuant  to   such

regulations,  during  a  single trading  day  no  trades  may  be

executed  at prices beyond the daily limit.  If the price  for  a

particular  futures  interest has increased or  decreased  by  an

amount  equal  to  the  daily limit, positions  in  such  futures

interest  can neither be taken nor liquidated unless traders  are

willing  to  effect  trades  at or  within  the  limit.   Futures

interests  prices  have occasionally moved the  daily  limit  for

several consecutive days with little or no trading.  Such  market

conditions   could   prevent   the  Partnership   from   promptly

liquidating  its futures interests and result in restrictions  on

redemptions.





                                

<PAGE>

     There  is  no  limitation on daily price  moves  in  trading

forward  contracts  on foreign currency.  The  markets  for  some

world  currencies have low trading volume and are illiquid, which

may   prevent   the  Partnership  from  trading  in   potentially

profitable  markets  or  from  promptly  liquidating  unfavorable

positions, subjecting it to substantial losses.  Either of  these

market conditions could result in restrictions on redemptions.



Capital  Resources.  The Partnership does not have, nor  does  it

expect  to  have,  any  capital assets.  Future  redemptions  and

exchanges  of  Units of Limited Partnership Interest  ("Unit(s)")

will  affect  the  amount of funds available  for  investment  in

futures interests in subsequent periods.  Since they are  at  the

discretion  of Limited Partners, it is not possible  to  estimate

the  amount  and therefore, the impact of future redemptions  and

exchanges.



Results of Operations

For the Quarter Ended March 31, 1999

For  the  quarter ended March 31, 1999, the Partnership  recorded

total  trading  revenues including interest income of  $2,510,122

and  posted  an increase in Net Asset Value per Unit.   The  most

significant  gains  were  recorded from short  positions  in  the

European common currency, the euro, as its value declined  versus

the U.S. dollar during February due to a recent economic slowdown

in  Europe  and fears that the European Central Bank would  lower

interest rates in an effort to stimulate growth.  During March,

<PAGE>

gains were recorded from short positions in the euro, as well  as

the Swiss franc, as the value of most European currencies dropped

due  to  the  growing  uncertainty regarding military  action  in

Yugoslavia.  Additional gains were recorded from short  positions

in  the Singapore dollar as its value slid lower against the U.S.

dollar  during  January as the Singapore government  allowed  its

currency to weaken in order to provide more of a cushion for  its

economy  against  a  downturn.  Gains were also  recorded  during

February from continued weakness in the Singapore dollar  as  its

value  slid to a five-month low in reaction to regional  economic

concerns  in the Pacific Rim.  These gains were partially  offset

by   losses  incurred  during  January  from  long  Japanese  yen

positions as the value of the yen reversed lower versus the  U.S.

dollar  after the Bank of Japan intervened to help ease  concerns

about  the impact of a strong yen on Japanese exports.   The  yen

experienced  additional  downward  pressure  later   in   January

following a devaluation of the Brazilian real, reports that China

may  devalue its currency and strong U.S. economic data.   Losses

recorded  from  long  yen positions were also experienced  during

February  as the value of the yen fell to a 2 1/2 month low  versus

the  U.S. dollar after several key Tokyo officials suggested that

Japanese  policy  markets  were  satisfied  with  a  weaker  yen.

Smaller  losses  were recorded during January  from  short  South

African  rand  positions during early January and  short  British

pound  positions  during  mid-January,  as  the  value  of  these

currencies  strengthened versus the U.S. dollar.  Total  expenses

for the three months ended March 31, 1999 were $1,815,170,



<PAGE>

resulting in net income of $694,952.  The value of a Unit in  the

Partnership  increased from $4,736.86 at  December  31,  1998  to

$4,767.18 at March 31, 1999.



For the Quarter Ended March 31, 1998

For  the  quarter ended March 31, 1998, the Partnership  recorded

total  trading  losses net of interest income of  $1,476,509  and

posted  a  decrease  in  Net  Asset Value  per  Unit.   The  most

significant  losses  were recorded from choppy  movement  in  the

value of the South African rand and Australian dollar relative to

the  U.S.  dollar during January and March.  Additional  currency

losses were experienced from short Japanese yen positions as  the

value  of  the  yen increased during January in reaction  to  the

Japanese  government's proposed economic stimulus  plan.   During

February,   smaller   losses  were  recorded  from   transactions

involving  the  yen  as its value moved in a short-term  volatile

pattern.   These  losses were mitigated by  gains  recorded  from

short  positions in the German mark and Swiss franc as the  value

of  the  U.S.  dollar strengthened relative to  these  currencies

during  March.  Additional profits were recorded from  short  New

Zealand  dollar positions as its value also decreased versus  the

U.S.  dollar  during March.  Total expenses for the three  months

ended March 31, 1998 were $1,263,499, resulting in a net loss  of

$2,740,008.   The  value of a Unit decreased  from  $4,435.47  at

December 31, 1997 to $4,333.33 at March 31, 1998.

                                

Year  2000 Problem.  Commodity pools, like financial and business

organizations and individuals around the world, depend on the

<PAGE>

smooth functioning of computer systems.  Many computer systems in

use  today cannot recognize the computer code for the year  2000,

but revert to 1900 or some other date.  This is commonly known as

the  "Year  2000  Problem". The Partnership  could  be  adversely

affected  if computer systems used by it or any third party  with

whom  it has a material relationship do not properly process  and

calculate date-related information and data concerning  dates  on

or  after January 1, 2000.  Such a failure could adversely affect

the  handling or determination of futures trades and  prices  and

other services.

     MSDW  began its planning for the Year 2000 Problem in  1995,

and  currently  has  several hundred  employees  working  on  the

matter.   It has developed its own Year 2000 compliance  plan  to

deal  with the problem and had the plan approved by the company's

executive   management,  Board  of  Directors   and   Information

Technology  Department.  Demeter is  coordinating  with  MSDW  to

address  the Year 2000 Problem with respect to Demeter's computer

systems that affect the Partnership.  This includes hardware  and

software upgrades, systems consulting and computer maintenance.

     Beyond  the challenge facing internal computer systems,  the

systems  failure  of  any  of the third  parties  with  whom  the

Partnership  has a material relationship - the futures  exchanges

and  clearing organizations through which it trades, Carr, or the

Trading  Advisors - could result in a material financial risk  to

the  Partnership.  All  U.S. futures  exchanges  are  subject  to

monitoring  by the CFTC of their Year 2000 preparedness  and  the

major  foreign futures exchanges are also expected to be  subject

to market-wide testing of their Year 2000 compliance during 1999.

<PAGE>                            Demeter intends to monitor  the

progress  of  Carr  and the Trading Advisors throughout  1999  in

their  Year  2000 compliance and, where applicable, to  test  its

external interface with Carr and the Trading Advisors.

      A  worst  case  scenario would be one in which  trading  of

contracts  on behalf of the Partnership becomes impossible  as  a

result of the Year 2000 problem encountered by any third parties.

A  less  catastrophic but more likely scenario would  be  one  in

which  trading  opportunities diminish as a result  of  technical

problems resulting in illiquidity and fewer opportunities to make

profitable trades. MSDW has begun developing various "contingency

plans" in the event that the systems of such third parties  fail.

Demeter  intends  to  consult closely with MSDW  in  implementing

those  plans.  Despite the best efforts of both Demeter and MSDW,

however,  it is possible that these steps will not be  sufficient

to avoid any adverse impact to the Partnership.

                                
Risks  Associated  With  the Euro.  On January  1,  1999,  eleven

countries  in  the  European Union established  fixed  conversion

rates on their existing sovereign currencies and converted  to  a

common   single  currency  (the  "euro").   During  a  three-year

transition  period,  the sovereign currencies  will  continue  to

exist  but  only as a fixed denomination of the euro.  Conversion

to the euro prevents the Trading Advisors from trading in certain

currencies and thereby limits their ability to take advantage  of

potential market opportunities that might otherwise have  existed

had  separate  currencies been available  to  trade.  This  could

adversely affect the performance results of the Partnership.

     <PAGE>

Item  3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT  MARKET
RISK

Introduction


The  Partnership  is a commodity pool engaged  primarily  in  the

speculative  trading of futures interests.  The market  sensitive

instruments  held  by  the Partnership are  acquired  solely  for

speculative   trading  purposes  and,  as  a   result,   all   or

substantially all of the Partnership's assets are subject to  the

risk  of trading loss.  Unlike an operating company, the risk  of

market sensitive instruments is integral, not incidental, to  the

Partnership's primary business activities.



The  futures interests traded by the Partnership involve  varying

degrees  of  related  market risk.  Such  market  risk  is  often

dependent  upon  changes in the level or volatility  of  interest

rates,   exchange  rates,  and/or  market  values  of   financial

instruments and commodities.  Fluctuations in related market risk

based  upon the aforementioned factors result in frequent changes

in  the  fair  value  of the Partnership's open  positions,  and,

consequently, in its earnings and cash flow.

                                

The  Partnership's  total market risk is  influenced  by  a  wide

variety  of factors, including the diversification effects  among

the Partnership's existing open positions, the volatility present

within  the  market(s), and the liquidity of the  market(s).   At

varying  times,  each of these factors may act to  exacerbate  or

mute the market risk associated with the Partnership.

                                

<PAGE>

The  Partnership's past performance is not necessarily indicative

of   its   future  results.   Any  attempt  at  quantifying   the

Partnership's  market  risk  must be qualified  by  the  inherent

uncertainty  of its speculative trading, which may  cause  future

losses and volatility (i.e. "risk of ruin") far in excess of  the

Partnership's   experience   to  date   and/or   any   reasonable

expectation premised upon historical changes in the fair value of

its market sensitive instruments.


Quantifying the Partnership's Trading Value at Risk


The    following    quantitative   disclosures   regarding    the

Partnership's  market  risk  exposures  contain  "forward-looking

statements"  within  the meaning of the safe  harbor  from  civil

liability  provided for such statements by the Private Securities

Litigation  Reform Act of 1995 (set forth in Section 27A  of  the

Securities Act of 1933 and Section 21E of the Securities Exchange

Act  of 1934).  All quantitative disclosures in this section  are

deemed to be forward-looking statements for purposes of the  safe

harbor, except for statements of historical fact.

                                

The Partnership accounts for open positions on the basis of mark-

to-market accounting principles.  As such, any loss in the fair

value  of  the Partnership's open positions is directly reflected

in  the  Partnership's earnings, whether realized or  unrealized,

and  the  Partnership's cash flow, as profits and losses on  open

positions of exchange-traded futures interests are settled  daily

through variation margin.

                                

<PAGE>

The  Partnership's  risk exposure in the various  market  sectors

traded  by  the Trading Advisors is estimated below in  terms  of

Value  at Risk ("VaR"). The VaR model employed by the Partnership

incorporates numerous variables that could impact the fair  value

of   the   Partnership's  trading  portfolio.   The   Partnership

estimates VaR using a model based on historical simulation with a

confidence   level   of  99%.   Historical  simulation   involves

constructing  a  distribution of hypothetical  daily  changes  in

trading  portfolio  value.  The VaR model  generally  takes  into

account linear exposures to price and interest rate risk.  Market

risks  that are incorporated in the VaR model include equity  and

commodity prices, interest rates, foreign exchange rates, as well

as   correlation   that  exists  among  these   variables.    The

hypothetical  changes  in  portfolio value  are  based  on  daily

observed percentage changes in key market indices or other market

factors  ("market  risk  factors")  to  which  the  portfolio  is

sensitive.   In the case of the Partnership's VaR, the historical

observation   period   is   approximately   four   years.     The

Partnership's one-day 99% VaR corresponds to the negative  change

in  portfolio  value that, based on observed market  risk  factor

moves, would have been exceeded once in 100 trading days.



VaR models such as the Partnership's are continually evolving  as

trading  portfolios  become more diverse and modeling  techniques

and systems capabilities improve.  It must also be noted that the

VaR  model is used to quantify market risk for historic reporting

purposes only and is not utilized by either Demeter or the

<PAGE>

Trading Advisors in their daily risk management activities.

                                

The Partnership's Value at Risk in Different Market Sectors


The  following  table  indicates  the  VaR  associated  with  the

Partnership's open positions as a percentage of total net  assets

by  market category as of March 31, 1999.  As of March 31,  1999,

the  Partnership's  total capitalization was  approximately  $113

million.

     Primary Market             March 31, 1999
     Risk Category              Value at Risk

     Currency                      (2.68)%

     Aggregate Value at Risk       (2.68)%



The  table  above  represents the VaR of the  Partnership's  open

positions   at  March  31,  1999  only  and  is  not  necessarily

representative  of  either the historic  or  future  risk  of  an

investment  in  the  Partnership.   As  the  Partnership's   sole

business   is  the  speculative  trading  of  primarily   futures

interests, the composition of its portfolio of open positions can

change significantly over any given time period or even within  a

single  trading  day.   Such  changes  in  open  positions  could

materially   impact  market  risk  as  measured  by  VaR   either

positively or negatively.



The table below supplements the quarter-end VaR by presenting the

Partnership's high, low and average VaR as a percentage of total





<PAGE>

net assets for the four quarterly reporting periods from April 1,

1998 through March 31, 1999.



Primary Market Risk Category        High       Low     Average

Currency                           (2.68)%   (0.79)%   (1.74)%

Aggregate Value at Risk            (2.68)%   (0.79)%   (1.74)%

Limitations on Value at Risk as an Assessment of Market Risk

The  face  value  of the market sector instruments  held  by  the

Partnership  is  typically  many  times  the  applicable   margin

requirements, as such margin requirements generally range between

2%  and 15% of contract face value.  Additionally, due to the use

of leverage, the face value of the market sector instruments held

by   the   Partnership  is  typically  many   times   the   total

capitalization  of the Partnership.  The financial  magnitude  of

the  Partnership's open positions thus creates a   "risk of ruin"

not  typically found in other investment vehicles.   Due  to  the

relative  size  of the positions held, certain market  conditions

may  cause  the Partnership to incur losses greatly in excess  of

VaR within a short period of time.  The foregoing VaR tables,  as

well  as  the  past  performance of  the  Partnership,  gives  no

indication of such "risk of ruin". In addition, VaR risk measures

should  be interpreted in light of the methodology's limitations,

which  include the following: past changes in market risk factors

will  not  always yield accurate predictions of the distributions

and correlations of future market movements; changes in portfolio

value  in  response  to  market movements  may  differ  from  the

responses implicit in a VaR model; published VaR results reflect

<PAGE>

past  trading  positions  while future  risk  depends  on  future

positions;  VaR  using  a  one-day time horizon  does  not  fully

capture the market risk of positions that cannot be liquidated or

hedged within one day; and the historical market risk factor data

used  for  VaR  estimation may provide only limited insight  into

losses  that  could  be  incurred under  certain  unusual  market

movements.



The foregoing VaR tables present the results of the Partnership's

VaR  at  March  31,  1999 and for the end of the  four  quarterly

reporting  periods  from April 1, 1998 through  March  31,  1999.

Since  VaR is based on historical data, VaR should not be  viewed

as  predictive of the Partnership's future financial  performance

or  its  ability to manage and monitor risk and there can  be  no

assurance  that the Partnership's actual losses on  a  particular

day will not exceed the VaR amounts indicated or that such losses

will not occur more than 1 in 100 trading days.



Non-Trading Risk

The  Partnership has non-trading market risk on its foreign  cash

balances not needed for margin.  However, such balances, as  well

as  any  market  risk  they may represent, are  immaterial.   The

Partnership  also maintains a substantial portion  (approximately

94%) of its available assets in cash at DWR.  A decline in short-

term interest rates will result in a decline in the Partnership's

cash  management  income. This cash flow risk is  not  considered

material.

                                

<PAGE>

Materiality,  as used throughout this section,  is  based  on  an

assessment  of  reasonably  possible  market  movements  and  the

potential  losses caused by such movements, taking  into  account

the   leverage,  optionality  and  multiplier  features  of   the

Partnership's market sensitive instruments.



Qualitative Disclosures Regarding Primary Trading Risk Exposures

The following qualitative disclosures regarding the Partnership's

market risk exposures - except for (i) those disclosures that are

statements  of historical fact and (ii) the descriptions  of  how

the  Partnership  manages  its primary market  risk  exposures  -

constitute  forward-looking  statements  within  the  meaning  of

Section  27A  of  the  Securities Act  and  Section  21E  of  the

Securities  Exchange Act.  The Partnership's primary market  risk

exposures  as  well  as the strategies used and  to  be  used  by

Demeter and the Trading Advisors for managing such exposures  are

subject  to numerous uncertainties, contingencies and risks,  any

one  of which could cause the actual results of the Partnership's

risk  controls to differ materially from the objectives  of  such

strategies.   Government  interventions,  defaults   and   expro-

priations,   illiquid   markets,  the   emergence   of   dominant

fundamental  factors, political upheavals, changes in  historical

price  relationships,  an  influx  of  new  market  participants,

increased  regulation  and many other  factors  could  result  in

material  losses  as  well as in material  changes  to  the  risk

exposures and the risk management strategies of the Partnership.



                                

<PAGE>

Investors  must be prepared to lose all or substantially  all  of

their investment in the Partnership.

                                
The  following  was  the primary trading  risk  exposure  of  the

Partnership as of March 31, 1999.  It may be anticipated however,

that market exposures will vary materially over time.

     Currency. The Partnership's currency exposure is to exchange

rate  fluctuations,  primarily  fluctuations  which  disrupt  the

historical pricing relationships between different currencies and

currency  pairs.  These fluctuations are influenced  by  interest

rate   changes   as  well  as  political  and  general   economic

conditions.   The  Partnership  trades  in  a  large  number   of

currencies,  including cross-rates - i.e., positions between  two

currencies   other   than   the  U.S.   dollar.    However,   the

Partnership's  major  exposures  have  typically  been   in   the

dollar/euro, dollar/ British pound, dollar/Singapore  dollar  and

dollar/ Swiss franc positions.  Demeter does not anticipate  that

the risk profile of the Partnership's currency sector will change

significantly  in  the future, although it is difficult  at  this

point  to predict the effect of the introduction of the  Euro  on

the Trading Advisors' currency trading strategies.



Qualitative Disclosures Regarding Non-Trading Risk Exposure

The  following  was  the only non-trading risk  exposure  of  the

Partnership as of March 31, 1999:





<PAGE>

Foreign  Currency  Balances.  The Partnership's  primary  foreign

currency balances are in Euros, British pounds, Singapore dollars

and  Swiss francs.  The Partnership controls the non-trading risk

of  these  balances by regularly converting these  balances  back

into  U.S.  dollars  at varying intervals,  depending  upon  such

factors as size, volatility, etc.



Qualitative Disclosures Regarding Means of Managing Risk Exposure

The  means  by  which the Partnership and the  Trading  Advisors,

severally,  attempt to manage the risk of the Partnership's  open

positions  are  essentially the same  in  all  market  categories

traded.   Demeter  attempts  to manage the  Partnership's  market

exposure  by  (i)  diversifying the  Partnership's  assets  among

different  Trading  Advisors, each of whose strategies  focus  on

different  market  sectors  and  trading  approaches,  and  (ii),

monitoring  the performance of the Trading Advisors  on  a  daily

basis.     In    addition,   the   Trading   Advisors   establish

diversification  guidelines, often set in terms  of  the  maximum

margin  to be committed to positions in any one market sector  or

market  sensitive instrument.  One should be aware  that  certain

Trading  Advisors  treat their risk control  policies  as  strict

rules, whereas others treat such policies as general guidelines.



Demeter monitors and controls the risk of the Partnership's  non-

trading   instrument,  cash,  which  is  the   only   Partnership

investment directed by Demeter, rather than the Trading Advisors.

                  PART II.   OTHER INFORMATION

Item 1.   LEGAL PROCEEDINGS

The  following supplements Legal Proceedings previously disclosed

in Item 3. of the Partnership's  1998 Form 10-K:



On  April  12,  1999,  the  defendants  filed  a  motion  in  the

California  action to oppose certification by the  court  of  the

class in the California litigation.



With  respect  to JWH, the New York Supreme Court  complaint  was

dismissed  with prejudice when the plaintiffs failed  to  replead

against  JWH in December, 1998.  Further, JWH has been  dismissed

as  a  defendant  in  the  California actions  without  prejudice

pursuant  to  a  tolling  agreement with plaintiffs  executed  in

January, 1999.



Item 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

Dean  Witter  Cornerstone Fund I ("Cornerstone I"),  Dean  Witter

Cornerstone   Fund  II  ("Cornerstone  II"),  and   Dean   Witter

Cornerstone  III  ("Cornerstone  III")  collectively   registered

250,000  Units pursuant to a Registration Statement on Form  S-1,

which  became  effective  on  May  31,  1984  (the  "Registration

Statement")  (SEC File Numbers 2-88587; 88587-01; 88587-02).   As

contemplated  in the Registration Statement, an additional  fund,

the Partnership, (collectively with Cornerstone I, Cornerstone II

and  Cornerstone  III,  the "Cornerstone Funds")  was  registered

pursuant  to  Post-Effective Amendment No. 5 to the  Registration

Statement,  which  became  effective on  February  6,  1987.  The

managing underwriter for the Cornerstone Funds is DWR.

<PAGE>

The  offering for Cornerstone IV originally commenced on February

6,  1987  and 100,633.696 Units have been sold through  April  1,

1999.   Through April 1, 1999, an aggregate of 235,422.053  Units

have been sold, leaving 14,577.947 Units remaining available  for

sale as of April 1, 1999.



The  aggregate  price of Units sold through April  1,  1999  with

respect to Cornerstone IV is $168,060,778.



Effective September 30, 1994, Cornerstone II, Cornerstone III and

Cornerstone IV were closed to new investors; Units have been sold

since  then  solely through "Exchanges" between  the  Cornerstone

Funds  only,  by existing Cornerstone investors, at 100%  of  Net

Asset  Value  per  Unit.   DWR has been paying  all  expenses  in

connection with the offering of Units since September  30,  1994,

without reimbursement.
