                  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 Diversified

Futures   Fund  III  L.P.  (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  Diversified Futures Fund  III  L.P.  is  a  limited

partnership  organized  to engage primarily  in  the  speculative

trading  of  commodity futures contracts and  forward  contracts,

physical    commodities,    and   other    commodity    interests

(collectively, "futures interests"). The general partner for  the

Partnership  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.

The  trading manager is Dean Witter Futures & Currency Management

Inc.  ("DWFCM" or the "Trading Manager").  Demeter, DWR and DWFCM

are wholly-owned subsidiaries of Morgan Stanley Dean Witter & Co.

("MSDW").


2. Related Party Transactions

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

<PAGE>

          DEAN WITTER DIVERSIFIED FUTURES FUND III L.P.
            NOTES TO FINANCIAL STATEMENTS (CONTINUED)


interests trading accounts to meet margin requirements as needed.

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

Treasury  bills.  The Partnership pays brokerage  commissions  to

DWR. Management fees and incentive fees (if any) incurred by  the

Partnership are paid to DWFCM.



3.  Financial Instruments

The  Partnership trades commodity futures contracts  and  forward

contracts,  physical commodities, and other commodity  interests.

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

<PAGE>

          DEAN WITTER DIVERSIFIED FUTURES FUND III L.P.
            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 on open contracts  is  reported  as  a

component  of  "Equity in futures interests trading accounts"  on

the  Statements of Financial Condition and totaled $2,873,599 and

$1,769,839  at  September  30,  1999  and  December   31,   1998,

respectively.



Of  the  $2,873,599  net unrealized gain  on  open  contracts  at

September 30, 1999, $2,735,952 related to exchange-traded futures

contracts  and  $137,647  related to off-exchange-traded  forward

currency contracts.



Of  the  $1,769,839  net unrealized gain  on  open  contracts  at

December 31, 1998, $4,225,604 related to exchange-traded  futures

contracts and $(2,455,765) related to off-exchange-traded forward

currency contracts.



Exchange-traded  futures contracts held  by  the  Partnership  at

September  30,  1999 and December 31, 1998 mature  through  March

2000

<PAGE>

          DEAN WITTER DIVERSIFIED FUTURES FUND III L.P.
            NOTES TO FINANCIAL STATEMENTS (CONTINUED)


and   June   1999,  respectively.   Off-exchange-traded   forward

currency contracts held by the Partnership at September 30,  1999

and  December  31, 1998 mature through December  1999  and  April

1999, respectively.



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 $54,439,801 and $67,947,328 at  September

30, 1999 and December 31, 1998, respectively.

          DEAN WITTER DIVERSIFIED FUTURES FUND III L.P.
            NOTES TO FINANCIAL STATEMENTS (CONCLUDED)


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

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



<PAGE>

from  promptly  liquidating its futures interests and  result  in

restrictions on redemptions.



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 of  Units

of  Limited Partnership Interest ("Units") 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.



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

$2,767,176  and posted an increase in Net Asset Value  per  Unit.

The  most  significant gains were recorded in the metals  markets

from  short gold futures positions as prices dropped during early

July amid

<PAGE>

disappointment  over  low  prices at  the  U.K.  auction.   Newly

established  long gold futures positions also produced  gains  as

prices  skyrocketed due to the results of the Bank  of  England's

second  gold  auction on September 21 and the announcement  of  a

plan by several European central banks to restrict sales of their

gold  reserves  for five years.  Additional gains  were  recorded

during  August  from  long aluminum futures positions  as  prices

increased  on  bullish technical factors and speculative  buying.

In  the  energy markets, gains were recorded from long crude  oil

futures positions as oil prices moved higher after OPEC ministers

confirmed  that  they  would uphold their global  cutbacks  until

April  of next year.  These gains were partially offset by losses

recorded from short Australian interest rate futures positions as

prices increased during July and August on the temporary strength

in U.S. bonds and weaker-than-expected business spending data out

of  Australia.  Additional losses were recorded from  short  U.S.

interest  rate  futures positions as domestic bond  prices  moved

temporarily  higher on the release of benign inflation  data  and

diminished fears of another interest rate increase by the Federal

Reserve.   Offsetting  gains resulted  from  short  positions  in

German bond futures as prices declined during July on comments by

Bundesbank President designate Welteke that he has started to see

signs  of  a resurgence in the European economy.  In the currency

markets,  losses were experienced early in the quarter from  long

Australian dollar positions as its value weakened versus the U.S.

dollar  due  to  depressed  commodities prices,  emerging  market

concerns and on-

<PAGE>

going  talks  that  China may eventually  devalue  its  currency.

Newly  established short positions in this currency  resulted  in

additional  losses  during September as  its  value  strengthened

relative  to the U.S. dollar following the rally in gold  prices.

Losses  were also experienced from long positions in the European

common  currency, the euro, and the Swiss franc as the  value  of

these  currencies  declined sharply versus  the  U.S.  dollar  on

September  10 as an intervention by the Bank of Japan temporarily

strengthened the U.S. dollar versus most major currencies.  As  a

result, new short positions were established in the euro and  the

Swiss  franc  only  to  result  in  additional  losses  as  these

currencies strengthened versus the U.S. dollar during the  latter

half  of  September after U.S. trade figures reflected  a  record

deficit.   Offsetting  currency gains  were  recorded  from  long

positions in the Japanese yen as the value of the yen climbed  to

a 44-month high versus the U.S. dollar amid optimism over Japan's

economic  recovery.  Total expenses for the  three  months  ended

September  30, 1999 were $1,370,848, resulting in net  income  of

$1,396,328.  The value of a Unit increased from $1,650.66 at June

30, 1999 to $1,693.26 at September 30, 1999.



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

recorded  total  trading revenues including  interest  income  of

$1,008,326  and, after expenses, posted a decrease in  Net  Asset

Value per Unit. The most significant losses were experienced in



<PAGE>

the  global  interest rate futures markets from short  Australian

interest  rate futures positions as prices increased during  July

and  August  on the temporary strength in U.S. bonds and  weaker-

than-expected   business   spending  data   out   of   Australia.

Additional losses were recorded from short Japanese bond  futures

positions  as  prices  increased during the  first  quarter  amid

growing  speculation  that  the  Bank  of  Japan  may  underwrite

Japanese  government bonds and during the third  quarter  on  the

strength  of  the  Japanese yen and expectations that  additional

monetary  easing  in  that country will come.   In  the  currency

markets, losses were recorded throughout a majority of the  first

quarter  from  long  Australian dollar  positions  as  its  value

dropped  significantly relative to the U.S. dollar on speculation

regarding  potential currency devaluations in the  Asian  region.

Early  in  the  third  quarter, losses were  recorded  from  long

positions  in this currency due to depressed commodities  prices,

emerging  market  concerns  and on-going  talks  that  China  may

eventually   devalue  its  currency.   Newly  established   short

positions in the Australian dollar resulted in additional  losses

during  September as its value strengthened relative to the  U.S.

dollar  following the rally in gold prices.  Offsetting  currency

gains  were recorded during the third quarter from long positions

in the Japanese yen as the value of the yen climbed to a 44-month

high  versus  the  U.S.  dollar due to  continued  optimism  over

Japan's  economic  recovery.  In the global stock  index  futures

markets, losses were experienced during February,



<PAGE>

mid-April  and May from long S&P 500 Index futures  positions  as

domestic  equity prices moved lower on concerns that the  Federal

Reserve  may  raise  interest  rates  in  an  effort  to  control

inflation.  These losses were partially offset by gains  recorded

in  the energy markets during March from long positions in  crude

and  heating oil futures as prices moved significantly higher  on

news  that  both  OPEC  and  non-OPEC countries  had  reached  an

agreement  to cut total output beginning April 1st.   Gains  were

also  recorded  in this market complex during the  third  quarter

after  OPEC  ministers  confirmed that they  would  uphold  their

global cutbacks until April of next year.  In the metals markets,

gains  were recorded from short gold futures positions as  prices

dropped  to  20  year lows during early July amid  disappointment

over low prices at the U.K. auction.  Newly established long gold

futures  positions  also resulted in gains as prices  skyrocketed

due  to  the results of the Bank of England's second gold auction

on  September 21 and an announcement by several European  central

banks that they plan to restrict sales of their gold reserves for

five  years.  Total expenses for the nine months ended  September

30,  1999 were $4,327,703, resulting in a net loss of $3,319,377.

The value of a Unit decreased from $1,783.35 at December 31, 1998

to $1,693.26 at September 30, 1999.









<PAGE>

For the Quarter and Nine Months Ended September 30, 1998

For  the  quarter  ended  September  30,  1998,  the  Partnership

recorded  total  trading revenues including  interest  income  of

$9,180,176  and posted an increase in Net Asset Value  per  Unit.

The most significant gains were recorded in the financial futures

markets  during  August  and September as  investors  sought  the

safety  of  fixed income investments in response  to  anticipated

interest  rate cuts by the U. S. Federal Reserve and  significant

volatility  in the global financial markets.  As a result,  gains

were  recorded from long global interest rate futures  positions,

particularly  U.S., Japanese and European bond futures.   Smaller

gains  were  recorded from long positions in Australian  interest

rate  futures  as  prices in these markets also  trended  higher.

Additional  gains  were recorded during July and  August  in  the

agricultural  markets  from short positions  in  corn  and  wheat

futures  as  grain  prices  continued  their  downward  trend  as

supplies remained abundant.  These gains were partially offset by

losses  recorded in the currency markets from long British  pound

positions  as  its value moved lower in response  to  uncertainty

about  economic  developments and interest rate  policy  in  that

country.   These losses, coupled with additional currency  losses

recorded  from transactions involving the Australian  dollar  and

Swedish krona during September, more than offset gains from  long

German mark positions.  Additional losses were recorded during



<PAGE>

July and September in the metals markets from short aluminum  and

copper  futures  positions as base metals prices reversed  higher

early  in the quarter.  Total expenses for the three months ended

September  30, 1998 were $1,571,988, resulting in net  income  of

$7,608,188.  The value of a Unit increased from $1,623.84 at June

30, 1998 to $1,823.02 at September 30, 1998.



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

recorded  total  trading revenues including  interest  income  of

$9,527,160  and posted an increase in Net Asset Value  per  Unit.

The most significant gains were recorded in the financial futures

markets  during the first and third quarters from  long  European

interest   rate  futures  positions.   Additional  profits   were

recorded from long positions in U.S. and Japanese bond futures as

prices  in  these  markets also trended higher during  the  third

quarter.   Smaller  gains were recorded in soft commodities  from

short  sugar  futures  positions as prices trended  lower  during

January,  February and September.  A portion of these  gains  was

offset  by losses in the metals and currency markets.  In metals,

losses  were  recorded during the first quarter from long  silver

futures  positions  as  silver  prices  reversed  lower  in  late

February  after  rallying higher during January.   In  September,

additional  losses  were  recorded  from  short  silver   futures

positions as precious metals prices moved higher due to



<PAGE>

uncertainty  in global stock markets and in the wake of  reported

difficulties  with  several  major  hedge  funds.   During  July,

smaller  losses  were  recorded from short  aluminum  and  copper

futures  positions  as base metals prices  reversed  higher.   In

currency   trading,   losses  were  recorded  from   transactions

involving the British pound as its value moved without consistent

direction  during the first nine months of the year.   Additional

currency  losses  were  recorded during  the  first  quarter  due

primarily  to  short-term  volatility  caused  by  the   economic

instability in the Far East.  During January, the upward trend in

the  value of the U.S. dollar reversed lower in response  to  the

Japanese  government's proposed economic stimulus  package,  thus

resulting in losses for previously established short Japanese yen

positions.  Additional currency losses were recorded in  February

as  the  value  of  the  yen moved without consistent  direction.

Total expenses for the nine months ended September 30, 1998  were

$4,884,538, resulting in net income of $4,642,622.  The value  of

a Unit increased from $1,692.08 at December 31, 1997 to $1,823.02

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

<PAGE>

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  Manager - 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

<PAGE>

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

Demeter  intends to monitor the progress of Carr and the  Trading

Manager throughout 1999 in their Year 2000 compliance and,  where

applicable,  to  test its external interface with  Carr  and  the

Trading Manager.



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 Manager from trading in certain

currencies and thereby limits its ability to take advantage of

<PAGE>

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.



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

<PAGE>

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.



The  Partnership's past performance is not necessarily indicative

of  its  future results. Any attempt at quantifying the  Partner-

ship'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

<PAGE>



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.



The  Partnership's  risk exposure in the various  market  sectors

traded  by  the Trading Manager 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

<PAGE>



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

Trading Manager 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 September 30, 1999.  As of September 30,

1999,  the  Partnership's total capitalization was  approximately

$54 million.

     Primary Market            September 30, 1999
     Risk Category                Value at Risk

     Currency                        (1.73)%

     Commodity                       (1.38)

     Interest Rate                   (0.94)

     Equity                          (0.17)

     Aggregate Value at Risk         (2.46)%







<PAGE>

Aggregate  value  at  risk represents the aggregate  VaR  of  the

Partnership's open positions and not the sum of the  VaR  of  the

individual categories listed above.  Aggregate VaR will be  lower

as  it  takes into account correlation among different  positions

and categories.


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

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                           (1.97)%    (0.95)%  (1.65)%

Commodity                         (1.38)      (0.90)   (1.10)

Interest Rate                      (1.92)     (0.54)   (1.06)

Equity                             (0.74)     (0.17)   (0.40)

Aggregate Value at Risk            (3.16)%    (1.37)%  (2.31)%
<PAGE>
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  require-

ments,  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 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.



<PAGE>

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

VaR  for each of the Partnership's market risk exposures and on  an

aggregate basis 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.



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

86%)  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 Demeter and the Trading  Manager

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  expropriations, 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  were the primary trading risk  exposures  of  the

Partnership as of September 30, 1999, by market sector.   It  may

anticipated  however,  that  these  market  exposures  will  vary

materially over time.

     Currency. The greatest exposure at September 30, 1999 in the

Partnership  was  in  the  currency complex.   The  Partnership's

currency  exposure  is  to exchange rate fluctuations,  primarily

fluctuations  that  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 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.









     <PAGE>

     Commodity.

     Metals.   The second greatest exposure was in the  base  and

precious metals markets. The Partnership's metals market exposure

in the third quarter of 1999 was to fluctuations in the prices of

base  metals, as well as exposure in the gold and silver markets.

A  significant amount of exposure was evident in the gold  market

as  the  price  of gold increased dramatically following  bullish

comments by the European Central Bank.

     The  Partnership aims to equally weight market  exposure  in

the  metals  as  much as possible, however, base  metals,  during

periods  of volatility, will affect performance more dramatically

than  the precious metals markets.  Demeter anticipates that base

metals  will  remain the primary metals market  exposure  of  the

Partnership.

     Energy.   On  September  30, 1999, the Partnership's  energy

exposure was in futures contracts in the New York and Brent crude

oil  markets.   Price  movements in  these  markets  result  from

political developments in the Middle East, weather patterns,  and

other  economic fundamentals.  As oil prices have increased about

100%  this  year, and, given that the agreement by  OPEC  to  cut

production  is  closing in on expiring in March of  2000,  it  is

possible that volatility will remain on the high end. Significant

profits and losses have been and are expected to continue  to  be

experienced in these markets.



     <PAGE>

     Soft  Commodities and Agriculturals.  On September 30, 1999,

the  Partnership  had significant exposure in  the  markets  that

comprise  these sectors.  Most of the exposure, however,  was  in

the  sugar  and  coffee markets.  Supply and demand inequalities,

severe  weather disruptions and market expectations affect  price

movements in these markets.

     Interest Rate.  The third greatest exposure this quarter was

in the interest rate sector. Exposure was spread across the U.S.,

Swiss,  Australian, and Japanese interest rate sectors.  Interest

rate  movements  directly affect the price of the sovereign  bond

positions held by the Partnership and indirectly affect the value

of  its  stock  index  and  currency  positions.   Interest  rate

movements  in  one  country  as well as  relative  interest  rate

movements  between countries materially impact the  Partnership's

profitability.  The Partnership's primary interest rate  exposure

is  generally to interest rate fluctuations in the G-7  countries

and  Australia.   Demeter  anticipates that  G-7  and  Australian

interest rates will remain the primary interest rate exposure  of

the  Partnership  for  the foreseeable future.   The  changes  in

interest  rates,  which have the most effect on the  Partnership,

are   changes   in   long-term   and   medium-term   instruments.

Consequently,  even a material change in short-term  rates  would

have  little  effect on the Partnership, were the  medium-to-long

term rates to remain steady.





     <PAGE>

      Equity.  The  Partnership's equity exposure on September  30,

1999  to  price risk in the Nikkei futures index and  the  S&P  500

futures  index  was small.  The stock index futures traded  by  the

Partnership are by law limited to futures on broadly based indices.

Demeter  anticipates  little, if any,  trading  in  non  G-7  stock

indices.   The  Partnership is primarily exposed  to  the  risk  of

adverse  price  trends or static markets in the U.S.  and  Japanese

indices.  (Static markets would not cause major market changes  but

would  make  it  difficult  for  the  Partnership  to  avoid  being

"whipsawed" into numerous small losses).



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 foreign currency

balances  are in Japanese yen, British pounds, euros, Swiss  francs

and  Australian dollars.  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  Manager,

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

positions are essentially the same in all market categories traded.





<PAGE>

Demeter attempts to manage the Partnership's market exposure by (i)

diversifying  the  Partnership's  assets  among  different   market

sectors   and   trading  approaches,  and  (ii),   monitoring   the

performance of the Trading Manager on a daily basis.  In  addition,

the  Trading Manager establishes diversification guidelines,  often

set in terms of the maximum margin to be committed to positions  in

any one market sector or market sensitive instrument.



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 Manager.
