                  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  managers to the Partnership are  John  W.  Henry  &

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

(collectively, the "Trading Managers").

           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.  Futures and forwards represent contracts for delayed

delivery  of  an instrument at a specified date and  price.  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  elected  to adopt the provisions  of  SFAS  No.  133

beginning  with  the  fiscal year that ended December  31,  1998.

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

the

           NOTES TO FINANCIAL STATEMENTS - (CONTINUED)




disclosure of average aggregate fair values and contract/notional

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 $3,499,373 and

$(2,827,252)  at  September  30,  1999  and  December  31,  1998,

respectively.

contracts  at  December  31, 1998 related to  off-exchange-traded

forward currency contracts.



Off-exchange-traded  forward  currency  contracts  held  by   the

Partnership  at September 30, 1999 and December 31,  1998  mature

through December 1999 and March 1999, respectively.

           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 $102,829,712 and $119,800,551 at September

30, 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





<PAGE>
                 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 and Nine Months Ended September 30, 1999

For  the  quarter  ended  September  30,  1999,  the  Partnership

recorded  total  trading revenues including  interest  income  of

$68,703 and, after expenses, posted a decrease in Net Asset Value

per  Unit.  The  most significant net losses were  recorded  from

short  positions in the euro and the Swiss franc as the value  of

these European currencies reversed their previous downward trend



<PAGE>

versus the U.S. dollar due to bullish economic data out of Europe

and  inflationary  fears in the U.S.  Losses were  also  recorded

from  transactions involving the euro and the Swiss franc  during

August  and September as the values of these currencies moved  in

short-term  volatile  patterns  relative  to  the  U.S.   dollar.

Additional  losses were incurred during July from long  positions

in the Australian dollar, amid depressed gold prices and emerging

market  concerns,  and during September from short  positions  in

this  Pacific  Rim currency, as its value strengthened  with  the

sudden  spike  in  gold prices.  Smaller losses were  experienced

during August from long positions in the Singapore dollar.  These

losses  were  partially  offset  by  gains  recorded  from   long

positions  in  the  Japanese  yen  as  the  value  of   the   yen

strengthened versus the U.S. dollar throughout a majority of  the

quarter amid optimism regarding the Japanese economy.  Additional

profits  were recorded from short positions in the Thai  baht  as

its  value  fell versus the U.S. dollar during September  due  to

lower-than-expected GDP data out of Thailand, the earthquakes  in

Taiwan  and  comments regarding the Thai economy by various  Thai

cabinet  members.  Total  expenses for  the  three  months  ended

September  30, 1999 were $2,083,248, resulting in a net  loss  of

$2,014,545.  The value of a Unit decreased from $4,726.08 at June

30, 1999 to $4,641.74 at September 30, 1999.



For  the  nine  months ended September 30, 1999, the  Partnership

recorded total trading revenues including interest income of

<PAGE>

$3,493,843  and, after expenses, posted a decrease in  Net  Asset

Value  per  Unit. The most significant net losses  were  incurred

from transactions involving the British pound during January  and

throughout the second quarter.  During January and April,  losses

were  incurred from short British pound positions  as  its  value

strengthened  versus  the  U.S.  dollar  on  optimism   regarding

economic growth prospects in that country.  During May and  June,

losses were experienced from long British pound positions as  the

value  of  the  pound weakened versus the U.S.  dollar  amid  the

possibility of another interest rate cut by the Bank of  England,

the  possibility  of Britain's entry into the  European  Monetary

Union  and  low  inflation in the U.K.   Additional  losses  were

experienced  from short Norwegian krone positions during  January

and March as its value strengthened versus the U.S. dollar due to

a  rise  in oil prices and the possibility that this Scandinavian

currency  could  be linked to the euro sometime  in  the  future.

Smaller  losses  were recorded during early  January  from  short

South  African  rand positions.  A portion of  these  losses  was

offset by gains recorded from short positions in the euro and the

Swiss franc as the value of these currencies weakened versus  the

U.S. dollar during the first two quarters due to an economic slow

down  in  Europe, fears that the European Central Bank would  cut

interest  rates,  the  crisis  in  Yugoslavia  and  concerns   of

inflation  and  an  interest rate hike in  the  U.S.   Additional

profits were recorded from long positions in the Japanese yen



<PAGE>

during  the  third  quarter as the value of the yen  strengthened

versus  the  U.S.  dollar as a result of optimism  regarding  the

Japanese  economy.   Total expenses for  the  nine  months  ended

September  30, 1999 were $5,768,517, resulting in a net  loss  of

$2,274,674.   The  value of a Unit decreased  from  $4,736.86  at

December 31, 1998 to $4,641.74 at September 30, 1999.



For the Quarter and Nine Months Ended September 30, 1998

For  the  quarter  ended  September  30,  1998,  the  Partnership

recorded   total  trading  losses  net  of  interest  income   of

$1,145,879 and posted a decrease in Net Asset Value per Unit. The

most  significant  losses were recorded  during  July  from  long

British  pound  positions as the value of the pound  moved  lower

relative  to  the  U.S. dollar after showing  signs  of  trending

higher  earlier in the month.  Smaller losses were recorded  from

transactions involving the British pound during the remainder  of

the quarter as its value failed to move with consistent direction

relative to the U.S. dollar.  The value of the Australian  dollar

also  moved in a trendless pattern versus the U.S. dollar  during

July and September resulting in additional losses recorded by the

Partnership.  Smaller losses were incurred during September  from

short Japanese yen positions as the value of the yen strengthened

versus the U.S. dollar.  This increase in the yen was spurred  by

several remarks from top finance officials in Tokyo stating  that

Japan was close to intervening in order to support the yen.  As a

result of this



<PAGE>

increase  in the yen, new long positions were established  during

mid-September, only to result in additional losses as  the  value

of  the  yen  reversed lower due to the failure of  the  Japanese

government to present any new initiatives toward economic  reform

in  that  country.  These losses were partially offset by profits

recorded during September from long German mark positions as  the

U.S. dollar weakened relative to most European currencies due  to

fears  over  the  White House scandal, continued  concerns  about

emerging markets and anticipation of an interest rate cut by  the

Federal  Reserve.  Additional currency gains were  recorded  from

long positions in the French franc as its value also strengthened

versus the U.S. dollar during September.  Total expenses for  the

three  months ended September 30, 1998 were $1,288,967, resulting

in  a net loss of $2,434,846.  The value of a Unit decreased from

$4,885.52 at June 30, 1998 to $4,788.38 at September 30, 1998.



For  the  nine  months ended September 30, 1998, the  Partnership

recorded  total  trading revenues including  interest  income  of

$15,607,755 and posted an increase in Net Asset Value  per  Unit.

The  most  significant profits were recorded during May and  June

from  short  South African rand positions as the  value  of  this

currency  fell  significantly lower relative to the  U.S.  dollar

despite an effort by the South African government to support  its

ailing  currency.  Additional gains were recorded from short  New

Zealand  dollar positions as its value also decreased versus  the

U.S. dollar during March, May and June.  Smaller gains were

<PAGE>

recorded from long French franc positions during September as the

value  of  the  U.S.  dollar  weakened  relative  to  most  major

currencies  due to fears over the White House scandal,  continued

concerns  about emerging markets and anticipation of an  interest

rate  cut  by  the Federal Reserve.  These gains  were  partially

offset  by  losses  experienced from transactions  involving  the

British  pound  as  its value moved without consistent  direction

during  the  first nine months of the year.  Smaller losses  were

recorded  during  July and September from transactions  involving

the  Australian  dollar as its value also moved  in  a  trendless

pattern relative to the U.S. dollar.  Total expenses for the nine

months ended September 30, 1998 were $6,567,113, resulting in net

income  of  $9,040,642.   The value  of  a  Unit  increased  from

$4,435.47  at  December 31, 1997 to $4,788.38  at  September  30,

1998.



Year  2000 Problem.  Commodity pools, like financial and business

organizations  and individuals around the world,  depend  on  the

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



<PAGE>

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  Managers - 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.

Demeter  intends to monitor the progress of Carr and the  Trading

Managers throughout 1999 in their Year 2000 compliance and, where



<PAGE>

applicable,  to  test its external interface with  Carr  and  the

Trading Managers.



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 Managers 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



<PAGE>

positions of exchange-traded futures interests are settled  daily

through variation margin.



The  Partnership's  risk exposure in the various  market  sectors

traded  by  the Trading Managers 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.





<PAGE>

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

Trading Managers in their daily risk management activities.



The Partnership's Value at Risk in its Market Sector

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 September 30, 1999.  As of September 30,

1999,  the  Partnership's total capitalization was  approximately

$105 million.

     Primary Market            September 30, 1999
     Risk Category              Value at Risk

     Currency                       (2.52)%

     Aggregate Value at Risk        (2.52)%


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

positions  at  September  30, 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



<PAGE>

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

Net  Assets for the four quarterly reporting periods from October

1, 1998 through September 30, 1999.



Primary Market Risk Category        High       Low     Average

Currency                           (3.48)%    (0.79)%   (2.37)%

Aggregate Value at Risk            (3.48)%    (0.79)%   (2.37)%

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

<PAGE>

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

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  September 30, 1999 and for the end of the four quarterly

reporting  periods  from October 1, 1998  through  September  30,

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.







<PAGE>

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

91%) 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.



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



<PAGE>

Demeter and the Trading Managers 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.

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  September 30, 1999.  It may  be  anticipated

however, that market exposure 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.  Interest rate changes as well as political  and

general  economic  conditions influence these fluctuations.   The

Partnership  trades  in  a large number of currencies,  including

cross-rates - i.e., positions between two currencies  other  than

the   U.S.   dollar.   For  the  third  quarter  of   1999,   the

Partnership's major exposures were in the euro currency crosses

and  outright U.S. dollar positions.  (Outright positions consist

of  the U.S. dollar vs. other currencies.  These other currencies

include  the  major  and  minor currencies).   Demeter  does  not

anticipate  that  the risk profile of the Partnership's  currency

sector  will  change significantly in the future.   The  currency

trading VaR figure includes foreign margin amounts converted into

U.S.  dollars  with  an  incremental adjustment  to  reflect  the

exchange  rate  risk inherent to the dollar-based Partnership  in

expressing VaR in a functional currency other than dollars.



Qualitative Disclosures Regarding Non-Trading Risk Exposure

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

Partnership as of September 30, 1999:



Foreign  Currency  Balances.  The Partnership's  primary  foreign

currency  balances are in British pounds, Japanese yen, Singapore

dollars,   euros,  and  South  African  rands.   The  Partnership

controls  the  non-trading risk of these  balances  by  regularly

converting  these balances back into dollars upon liquidation  of

the respective position.



Qualitative Disclosures Regarding Means of Managing Risk Exposure

The  means  by  which the Partnership and the  Trading  Managers,

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

positions are essentially the same in all market categories



<PAGE>

traded.   Demeter  attempts  to manage the  Partnership's  market

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

different  Trading  Managers, each of whose strategies  focus  on

different   trading   approaches,  and   (ii),   monitoring   the

performance  of  the  Trading  Managers  on  a  daily  basis.  In

addition,   the   Trading   Managers  establish   diversification

guidelines,  often  set  in terms of the  maximum  margin  to  be

committed  to  positions in any one market-sensitive  instrument.

One  should  be aware that certain Trading Managers  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 Managers.
