Dear Shareholder:
Investors who purchased shares of Putnam Health Sciences Trust when it was
introduced on May 28, 1982, and reinvested all distributions in additional
shares saw their investment increase in value by nearly 10 times at the close
of the fund's fiscal year on August 31, 1997 -- a healthy return indeed. While
past results can never be taken as a guarantee of future returns, performance
over other periods, as shown in the table on page 9, was similarly positive.
The fund enters its 16th full fiscal year with a new team of managers. Richard
England, formerly with Aetna Equity Investors, joined Putnam in 1992 and has
11 years of investment experience. Roland W. Gillis, who has been with Putnam
since 1995, was formerly with Keystone Custodian Funds and Loomis Sayles & Co.
and has been in investment management for 22 years. David G. Carlson, who
joined Putnam in 1990 from Coopers & Lybrand, has 9 years of investment
experience.
Respectfully yours,
/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
October 15, 1997
Report from the Fund Managers
Richard B. England, lead manager
Roland W. Gillis
David G. Carlson
Putnam Health Sciences Trust's strategy of spreading assets across companies
of all sizes remained a key factor in its solid performance during the second
half of fiscal 1997. The stocks of large companies, especially those in the
pharmaceutical sector, represented a significant portion of your fund's
portfolio and contributed greatly to returns. Over the 12 months ended August
31, 1997, record-breaking surges in a number of large-company indexes,
including a rise above 8000 for the Dow Jones Industrial Average, were
accompanied by generally dreary performance from the stocks of smaller
companies. Indeed, for this period, which is your fund's fiscal year, the
Standard & Poor's 500(registered trademark) Index, which is weighted in favor
of large-company stocks, returned 40.62%, while the Russell 2000 Index, a
measure of small-company stocks, gained 28.96%.
Despite this challenging environment, we drew upon the strongest sectors in
the health-care industry, targeting companies that we expected would benefit
from long-term trends rather than short-term economic fluctuations. For the
August 31, 1997, fiscal year, your fund's class A shares provided an
impressive total return of 32.46% at net asset value. The return taking
maximum sales charges into account was 24.85%. For complete performance
information, please refer to the summary that begins on page 9.
* BANNER YEAR FOR PHARMACEUTICAL STOCKS
In the fund's semiannual report, we noted that stocks of many pharmaceutical
companies had delivered strong returns as the companies developed, tested, and
received approval for new drugs. We're happy to report that this trend
continued through the remainder of fiscal 1997. Since one of the most
effective ways to control spiraling medical costs is to keep people out of the
hospital, the ability to develop effective drugs with minimal side effects has
become a very valuable asset. A number of pharmaceutical companies in your
fund's portfolio are now dominating global markets by creating innovative
products for the treatment and prevention of disease.
Warner-Lambert Company, for example, recently was cleared to market Rezulin, a
drug for diabetes patients who are newly diagnosed or have problems with
traditional insulin treatments. Approximately 16 million people in the United
States have diabetes, and new guidelines for early diagnosis endorsed by the
American Diabetes Association are expected to reveal an additional 2 million.
The disease is estimated to cost the U.S. health-care system more than $100
billion annually. The strong performance of Warner-Lambert's stock can be
attributed in part to this drug and also to the company's development of
Lipitor, a drug for the treatment of high cholesterol. The company is expected
to benefit greatly from this product, since the U.S. cholesterol drug market
was estimated at more than $3 billion for 1996 and is expected to increase by
30% by the end of 1997. The worldwide market is estimated to total an
additional $7 billion.
Another standout among the portfolio's pharmaceutical holdings was
Schering-Plough Corp., developer of Claritin, the number one prescription
antihistamine in the world. U.S. sales of this drug have risen strongly in
calendar 1997, and Schering-Plough is expected to get approval soon to market
Claritin in Japan, the world's second largest pharmaceutical market. Another
leading Schering-Plough product, Intron A, is an antiviral and cancer
treatment that has contributed greatly to the company's solid performance so
far in 1997. Use of Intron A as a treatment for malignant melanoma and
hepatitis C has increased significantly in the United States. While these
holdings, along with others discussed in this report, were viewed favorably at
the end of the fiscal period, all portfolio holdings are subject to review and
adjustment in accordance with the fund's investment strategy and may vary in
the future.

Footnote reads:
*Based on net assets as of 8/31/97. Holdings will vary over time.
* MEDICAL DEVICES: ANOTHER PROFITABLE SECTOR
Companies that develop innovative medical devices, especially those that
control the rhythm of the heart, were significant contributors to your fund's
performance in fiscal 1997. Guidant Corp., for example, has had great success
with the Ventak AV, an electrode system that is implanted into a patient's
shoulder to monitor and control heart activity. The Ventak AV is the only
device on the market that is able to both pace and defibrillate an irregular
heartbeat. Guidant Corp. is also known for its coronary stent -- a metal tube
or coil that is used to keep arteries open. Guidant's Multi-Link stent was
approved recently for sale in Japan and should be approved for sale in the
United States within the next 6 to 9 months.
One of the small companies in your fund's portfolio, Arterial Vascular
Engineering, Inc. (AVEI), has also made great progress with coronary stent
systems. The company has the number-one-selling stent in Europe and recently
received clearance to sell its entire line of devices in Japan. Both AVEI and
Guidant are expected to be the first major competitors of pharmaceutical giant
Johnson & Johnson in the U.S. coronary stent market.
* SMALL BIOTECH COMPANIES HELP FISCAL '97 RETURNS
While small-company stocks endured a tough year and represented a smaller
portion of your fund's portfolio, several are worth noting, including Guilford
Pharmaceuticals, Inc., a biotechnology company. Guilford recently announced a
patent for its Gliadel Wafer, a compound used for postsurgical treatment of
brain cancer. The product is designed to target specific tumors while
minimizing the adverse side effects that have been present with other
treatments. Guilford is also known for its efforts to develop treatments for
neurological diseases like Parkinson's disease. Also in 1997, Guilford's stock
was boosted by the company's alliance with Amgen, another biotechnology
company. Under the agreement, Amgen will receive worldwide rights to several
of Guilford's neurological compounds and will conduct clinical development,
manufacturing, and marketing of the products.

Footnote reads:
These holdings represent 33.7% of the fund's
net assets as of 8/31/97. Portfolio holdings will
vary over time.
Another small-company biotech holding, Medimmune, Inc., recently presented
very positive clinical results for MEDI-493, a drug designed to prevent RSV, a
life-threatening respiratory virus in infants. Medimmune expects to receive
FDA approval in the near future, which should present a large market
opportunity.
Despite these success stories, the biotechnology industry as a whole was
disappointing during fiscal 1997, and our decision to maintain an
underweighted position in this sector proved to be a prudent one. Of course,
we will continue to monitor this sector carefully and to shift portfolio
weightings appropriately.
* PROMISING NEW FISCAL YEAR ANTICIPATED
Despite disappointments in the hospital, health maintenance organization
(HMO), and biotechnology sectors, we have been able to uncover opportunities
in many health-care sectors that have contributed to stellar returns for
fiscal 1997. As we enter a new fiscal year, we remain optimistic about a
number of promising industry trends, including mergers, acquisitions, and an
aging population that will favor virtually every health-care sector. Of
course, we will continue to diversify across a variety of health-care
subsectors, seeking stocks with long-term growth potential.
The views expressed here are exclusively those of Putnam Management. They are
not meant as investment advice. Although the described holdings were viewed
favorably as of 8/31/97, there is no guarantee the fund will continue to hold
these securities in the future. Funds investing in a single sector may be
subject to more volatility than funds investing in a diverse group of sectors.

Returns for class A and class M shares reflect the current maximum initial
sales charges of 5.75% for class A shares and 3.50% for class M shares.
One-, five-, and ten-year (when available) returns for class B shares
reflect the applicable contingent deferred sales charge (CDSC), which is
5% in the first year, declines each year to 1% in the sixth year, and is
eliminated thereafter. Returns shown for class B and class M shares for
periods prior to their inception are derived from the historical
performance of class A shares, adjusted to reflect both the initial sales
charge or CDSC, if any, currently applicable to each class and, in the
case of class B and class M shares, the higher operating costs applicable
to such shares. All returns assume reinvestment of distributions at NAV
and represent past performance; they do not guarantee future results.
Investment return and principal value will fluctuate so that an investor's
shares when redeemed may be worth more or less than their original cost.

Performance data represent past results, do not reflect future

TERMS AND DEFINITIONS
Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested all
distributions in the fund.
Class A shares are generally subject to an initial sales charge.
Class B shares may be subject to a sales charge upon redemption.
Class M shares have a lower initial sales and a higher 12b-1 fee than
class A shares and no sales charge on redemption.
Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.
Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the maximum 5.75% sales charge for class A
shares and 3.50% for class M shares.
Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B shares and assumes redemption at the end of the
period. Your fund's CDSC declines from a 5% maximum during the first year
to 1% during the sixth year. After the sixth year, the CDSC no longer
applies.

Notes to financial statements
August 31, 1997
Note 1
Significant accounting policies
Putnam Health Sciences ("the fund") is registered under the Investment Company
Act of 1940, as amended, as a diversified, open-end management investment
company. The investment objective of the fund is to seek capital appreciation
by investing primarily in the common stocks of companies in the health
sciences industries.
The fund offers class A, class B and class M shares. Class A shares are sold
with a maximum front-end sales charge of 5.75 %. Class B shares, which convert
to class A shares after approximately eight years, do not pay a front-end
sales charge, but pay a higher ongoing distribution fee than class A shares,
and are subject to a contingent deferred sales charge, if those shares are
redeemed within six years of purchase. Class M shares are sold with a maximum
front-end sales charge of 3.50% and pay an ongoing distribution fee that is
lower than class B shares and higher than class A shares.
Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class (including
the distribution fees applicable to such class). Each class votes as a class
only with respect to its own distribution plan or other matters on which a
class vote is required by law or determined by the Trustees. Shares of each
class would receive their pro-rata share of the net assets of the fund, if the
fund were liquidated. In addition, the Trustees declare separate dividends on
each class of shares.
The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
preparation of financial statements is in conformity with generally accepted
accounting principles and requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities. Actual
results could differ from those estimates.
A) Security valuation Investments for which market quotations are readily
available are stated at market value, which is determined using the last
reported sale price, or if no sales are reported -- as in the case of some
securities traded over-the-counter -- the last reported bid price. Short-term
investments having remaining maturities of 60 days or less are stated at
amortized cost, which approximates market value, and other investments are
stated at fair value following procedures approved by the Trustees. Foreign
securities quoted in foreign currencies are translated into U.S. dollars at
the current exchange rate.
B) Joint trading account Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the fund may transfer uninvested cash
balances into a joint trading account along with the cash of other registered
investment companies and certain other accounts managed by Putnam Investment
Management, Inc. ("Putnam Management"), the fund's manager, a wholly-owned
subsidiary of Putnam Investments, Inc. These balances may be invested in one
or more repurchase agreements and/or short-term money market instruments.
C) Repurchase agreements The fund, or any joint trading account, through its
custodian, receives delivery of the underlying securities, the market value of
which at the time of purchase is required to be in an amount at least equal to
the resale price, including accrued interest. Putnam Management is responsible
for determining that the value of these underlying securities is at all times
at least equal to the resale price, including accrued interest.
D) Security transactions and related investment income Security transactions
are accounted for on the trade date (date the order to buy or sell is
executed). Interest income is recorded on the accrual basis. Dividend income
is recorded on the ex-dividend date except that certain dividends from foreign
securities are recorded as soon as the fund is informed of the ex-dividend
date.
E) Foreign currency translation The accounting records of the fund are
maintained in U.S. dollars. The market value of foreign securities, currency
holdings, other assets and liabilities are recorded in the books and records
of the fund after translation to U.S. dollars based on the exchange rates on
that day. The cost of each security is determined using historical exchange
rates. Income and withholding taxes are translated at prevailing exchange
rates when accrued or incurred. The fund does not isolate that portion of
realized or unrealized gains or losses resulting from changes in the foreign
exchange rate on investments from fluctuations arising from changes in the
market prices of the securities. Such fluctuations are included with the net
realized and unrealized gain or loss on investments. Net realized gains and
losses on foreign currency transactions represent net exchange gains or losses
on closed forward currency contracts, disposition of foreign currencies and
the difference between the amount of investment income and foreign withholding
taxes recorded on the fund's books and the U.S. dollar equivalent amounts
actually received or paid. Net unrealized appreciation and depreciation of
assets and liabilities in foreign currencies arise from changes in the value
of open forward currency contracts and assets and liabilities other than
investments at the period end, resulting from changes in the exchange rate.
F) Federal taxes It is the policy of the fund to distribute all of its taxable
income within the prescribed time and otherwise comply with the provisions of
the Internal Revenue Code applicable to regulated investment companies. It is
also the intention of the fund to distribute an amount sufficient to avoid
imposition of any excise tax under Section 4982 of the Internal Revenue Code
of 1986. Therefore, no provision has been made for federal taxes on income,
capital gains or unrealized appreciation on securities held and for excise tax
on income and capital gains.
G) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date. Capital
gain distributions, if any, are recorded on the ex-dividend date and paid at
least annually. The amount and character of income and gains to be distributed
are determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. Reclassifications are made to the
fund's capital accounts to reflect income and gains available for distribution
(or available capital loss carryovers) under income tax regulations. For the
year ended August 31, 1997, the fund required no such reclassifications.
Note 2
Management fee, administrative services and other transactions
Compensation of Putnam Management for management and investment advisory
services is paid quarterly based on the average net assets of the fund. Such
fee is based on the following annual rates: 0.70% of the first $500 million of
average net assets, 0.60% of the next $500 million, 0.55% of the next $500
million, 0.50% of the next $5 billion, 0.475% of the next $5 billion, 0.455%
of the next $5 billion, 0.44% of the next $5 billion and 0.43% thereafter.
Prior to December 20, 1996 any amount over $1.5 billion was based on 0.50%.
The fund reimburses Putnam Management for the compensation and related
expenses of certain officers of the fund and their staff who provide
administrative services to the fund. The aggregate amount of all such
reimbursements is determined annually by the Trustees.
Custodial functions for the fund's assets are provided by Putnam Fiduciary
Trust Company (PFTC), a wholly-owned subsidiary of Putnam Investments, Inc.
Investor servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.
For the year ended August 31, 1997, fund expenses were reduced by $536,267
under expense offset arrangements with PFTC and brokerage service
arrangements. Investor servicing and custodian fees reported in the Statement
of operations exclude these credits. The fund could have invested a portion of
the assets utilized in connection with the expense offset arrangements in an
income producing asset if it had not entered into such arrangements.
Trustees of the fund receive an annual Trustees fee of $2,130 and an
additional fee for each Trustee's meeting attended. Trustees who are not
interested persons of Putnam Management and who serve on committees of the
Trustees receive additional fees for attendance at certain committee meetings.
The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan") which
allows the Trustees to defer the receipt of all or a portion of Trustees Fees
payable on or after July 1, 1995. The deferred fees remain in the fund and are
invested in certain Putnam funds until distribution in accordance with the
Deferral Plan.
The fund has adopted an unfunded noncontributory defined benefit pension plan
(the "Pension Plan") covering all Trustees of the fund who have served as
Trustee for at least five years. Benefits under the Pension Plan are equal to
50% of the Trustee's average total retainer and meeting fees for the three
years preceding retirement. Pension expense for the fund is included in
Compensation of trustees in the Statement of operations. Accrued pension
liability is included in Payable for compensation of Trustees in the Statement
of assets and liabilities.
The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B and class M shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to compensate
Putnam Mutual Funds Corp., a wholly-owned subsidiary of Putnam Investments
Inc., for services provided and expenses incurred by it in distributing shares
of the fund. The Plans provide for payments by the fund to Putnam Mutual Funds
Corp. at an annual rate up to 0.35%, 1.00% and 1.00% of the average net assets
attributable to class A, class B and class M shares, respectively. The
Trustees have approved payment by the fund at an annual rate of 0.25%, 1.00%
and 0.75% of the average net assets attributable to class A, class B and class
M shares respectively.
For the year ended August 31, 1997, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $862,756 and $33,622 from the sale of
class A and class M shares, respectively and $611,861 in contingent deferred
sales charges from redemptions of class B shares. A deferred sales charge of
up to 1% is assessed on certain redemptions of class A shares. For the year
ended August 31, 1997, Putnam Mutual Funds Corp., acting as underwriter
received $4,102 on class A redemptions.
Note 3
Purchase and sales of securities
During the year ended August 31, 1997, purchases and sales of investment
securities other than short-term investments aggregated $1,081,450,155 and
$770,821,219, respectively. There were no purchases and sales of U.S.
government obligations. In determining the net gain or loss on securities
sold, the cost of securities has been determined on the identified cost basis.
