Fellow Shareholders
The first half of 1998 was beneficial for health sciences stocks, which as a
whole posted double-digit gains. The pharmaceutical sector turned in some of the
best results, as investors showed a preference for large companies with stable
earnings growth in an uncertain market. Returns of health care services stocks
were mixed, as were the results from the products and devices sector.
Biotechnology stocks generally lagged.

Your fund finished the six months ended June 30, 1998 with a 10.10% gain. For
the one-year period, the fund posted a 17.75% total return. These results fell
somewhat short of those for the Lipper Health/Biotechnology Fund Index due to an
overweighting early in the period in smaller-cap companies, especially in the
biotechnology sector. Both the fund and its peer group were well behind the
unmanaged Standard & Poor's 500 Stock Index for these periods, which soared on
investor demand for large, liquid companies.
Market Environment
The surprisingly lengthy bull market for U.S. equities extended into the first
half of 1998. Low interest rates and inflation, solid mutual-fund investment
flows, and record merger-and-acquisition activity helped power many stock
indices to record levels. While corporate profits remained healthy in early
1998, there was evidence that earnings growth may be weakening. Asia's economic
troubles were another major cloud on the horizon. As a result, investors once
again favored highly liquid, large capitalization stocks, as illustrated by the
performance of the S&P 500 (up almost 18%) versus the small-cap Russell 2000
Index (up only 5%).
The first half of 1998 will also be remembered for the staggering size and value
of the corporate deals. Eight of the 10 largest corporate
1
<PAGE>
transactions ever assembled were announced between January 1 and June 30, 1998,
and included such proposed mergers as Travelers/Citicorp, Monsanto/American
Home Products, and Mercedes Benz/Chrysler. These deals spanned a number of
industries and served to draw even more attention to the large-cap universe of
stocks.
The market for health sciences stocks was generally favorable in the first half
of 1998, especially for stocks of large companies with steady earnings. The
pharmaceutical sector, for example, led both the health care sector and the
broader market. Pharmaceuticals have met investor demand for consistent earnings
growth and have been rewarded with ever-increasing stock values. Health
maintenance organization (HMO) stocks also did well, rebounding off their
December lows after fears regarding the collapse of Oxford Health Plans abated
and investors gained confidence that future premium increases would exceed
expense growth. Health care information stocks were good performers as
underlying demand remained strong.
The health sciences sector is diverse and dynamic and represents one of the most
attractive growth areas in the global economy.
Other areas of the health care services sector, however, were less successful.
Health care provider stocks, such as physician practice management companies,
underperformed because of earnings shortfalls and uncertainty regarding changes
in Medicare reimbursement. These stocks were also held back by lower projected
earnings growth rates after the Securities and Exchange Commission shortened
mandated acquisition cost amortization periods -- an accounting change that
pinches the bottom line in the short term. Products and devices companies also
posted mixed results, with the difference between the stronger and weaker
performers defined by the ability of their product cycles to fuel future
earnings growth. Biotechnology stocks were volatile during the first half of
1998 and generally trailed the overall market. The American Stock Exchange
Biotechnology Index declined 10% during the first six months of the year.
Portfolio Review
As noted in a special letter to you this past February, I became chairman of
this fund's Investment Advisory Committee in March. Given this change in
portfolio management, we thought it would be helpful to explain our approach to
investing and some changes we have made
2
<PAGE>
over the past few months. The health sciences sector is diverse and dynamic and
represents one of the most attractive growth areas in the global economy. We
divide the health sciences universe into four major areas: services, products
and devices, pharmaceuticals, and biotechnology. As you can see from the
portfolio section of this report, we then divide each of these into as many as
four subsectors. This gives us an organized means of viewing the landscape for
investment opportunities.
We search for themes that will drive the various sectors of the health sciences
universe and create more fertile areas of investment. We choose stocks from the
bottom up, based on our analysis of current and expected fundamentals and on
each security's valuation. Our general bias is toward mid- to large-cap
companies with visible growth drivers, which we view as the core of the
portfolio. We seek to supplement the portfolio with investments ranging from
rapidly growing small-cap companies to out-of-favor large-cap stocks.
Currently, the themes we seek to exploit include:
. The development of drug innovations to address major medical needs, e.g.
cardiovascular disease, cancer, and diabetes, by such companies as Pfizer,
Bristol-Myers Squibb, and Warner-Lambert.
. The development of life-saving and lifestyle-enhancing devices by companies
such as Medtronic, Boston Scientific, and Arterial Vascular Engineering.
. The growing importance of health care information management systems
provided by companies such as IDX Systems, National Data, and Access Health
Marketing.
. The breakthrough products being discovered and developed by biotechnology
companies such as Centocor, Biogen, and MedImmune.
. The ability of advances in drug delivery to improve patient health and to
extend pharmaceutical economic life cycles. Companies include Elan,
Alkermes, and R.P. Scherer.
In keeping with our strategy and current market trends, we made a number of
changes in both sector weightings and individual stock holdings. Our goals were
to increase exposure to companies with more tangible growth prospects and to
raise the overall market cap and trading liquidity of the fund's holdings. As a
result, holdings in the pharmaceutical
3
<PAGE>
sector increased significantly from year-end 1997, while the services, products
and devices, and biotechnology sectors all declined as a percentage of assets.

The fund's pharmaceutical weighting grew because of additional investments and
the generally superior performance of the sector. New positions were initiated
in large-cap companies, such as Schering-Plough, American Home Products, and
Astra. We also purchased stocks in mid-size pharmaceutical companies such as
Elan, Shire Pharmaceuticals, and Watson Pharmaceuticals. We believe these
mid-cap companies offer a good combination of superior growth prospects and
attractive relative valuations. Positions were increased in Bristol-Myers
Squibb, Alkermes, and Johnson & Johnson, while holdings in Japanese
pharmaceutical companies Takeda Chemical Industries and Banyu Pharmaceutical
were eliminated. Significant contributors to the fund's first half performance
included Pfizer, Warner-Lambert, and R.P. Scherer. Laggards included Dura
Pharmaceuticals and PathoGenesis.
Service company holdings were trimmed as we selectively took profits after a
first half rebound. Positions in PacifiCare Health Systems and Nationwide Health
Properties were eliminated, and holdings in IDX Systems, National Data, and
Synetic were reduced. New investments included Wellpoint, a California-based
provider of health insurance and managed care services, Access Health Marketing,
a provider of health care information and analytical services, and Total Renal
Care Holdings, a leading provider of kidney dialysis services. In other areas,
our health care service holdings lagged in the first half, with notable
underperformers including PhyCor, American Oncology Resources, and Concentra
Managed Care.
Performance of the fund's products and devices investments was mixed. We took
advantage of share price volatility to initiate positions in Guidant and
Arterial Vascular Engineering, two leading providers of devices for the
cardiovascular system. We cut back positions in Collagen and Smith & Nephew as
part of our efforts to raise the level
4
<PAGE>
and predictability of the portfolio's overall growth rate. Investments in
NeoPath, Pall, and St. Jude Medical were eliminated for similar reasons. We sold
holdings in United States Surgical shortly after it agreed to be acquired by
Tyco International.
Exposure to the biotechnology sector declined appreciably as several of our
former holdings either underperformed or no longer met our investment criteria.
We continue to believe that the biotechnology industry is a fertile investment
area with the potential for significant gains. However, consistent with our
desire to enhance earnings visibility and predictability, we focused our
biotechnology holdings on companies with either established products or products
in the later stages of development and approval. The number of holdings in the
sector was reduced from 22 to 13; some of those eliminated included Bone Care
International, Synaptic Pharmaceutical, and CytoTherapeutics. We believe the
current negative sentiment toward the biotechnology sector is excessive and
anticipate increasing our exposure to take advantage of the improved risk/reward
tradeoff.
Investment Outlook
We believe that the health sciences sector will continue to be a dynamic growth
area offering many investment opportunities. The field is driven by three major
forces: insatiable global demand by aging populations and better-educated young
and middle-aged consumers; significant financial resources, provided by internal
profit growth and external investment capital; and continuous advances in health
care technology and the health care delivery system. The pace of scientific
discovery is accelerating as we reap the benefits of extensive research and
development investments as well as advances in analytical and computing
technologies.
. . .there are a number of rapidly growing areas within the health care service
sector, such as information and analytical services.
For the immediate future, we view pharmaceutical companies and the products and
devices sector as the central beneficiaries of these forces. These companies
have the right products and the global distribution systems needed to maximize
returns on their investments. Biotechnology companies will be significant but
more volatile beneficiaries of these trends, and we expect to take an aggressive
approach to opportunities in the sector. Health care services firms will provide
a
5
<PAGE>
more diverse set of rewards and challenges. The pricing pressures on health care
providers are not likely to abate soon, and we currently have moderate
expectations for revenue and profit growth. Yet there are a number of rapidly
growing areas within the sector, such as information and analytical services.
Our greatest concerns at the moment are the divergent performances and valuation
discrepancies between large- and small-cap stocks in general and the
historically high valuations being accorded to fundamentally attractive sectors,
such as pharmaceuticals and devices. We are taking a measured approach to
increasing the visibility and predictability of the fund's growth profile. Our
underlying belief is that stock prices follow earnings and that a patient
approach will reward our fellow shareholders over the long term. We would like
to thank you for your continued support and reaffirm our commitment to finding
good investment opportunities on your behalf.
Respectfully submitted,

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
T. Rowe Price Health Sciences Fund, Inc. (the fund) is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company and commenced operations on December 31, 1995.
The accompanying financial statements are prepared in accordance with
generally accepted accounting principles for the investment company industry;
these principles may require the use of estimates by fund management.
Valuation Equity securities listed or regularly traded on a securities
exchange are valued at the last quoted sales price on the day the valuations are
made. A security which is listed or traded on more than one exchange is valued
at the quotation on the exchange determined to be the primary market for such
security. Listed securities not traded on a particular day and securities
regularly traded in the over-the-counter market are valued at the mean of the
latest bid and asked prices. Other equity securities are valued at a price
within the limits of the latest bid and asked prices deemed by the Board of
Directors, or by persons delegated by the Board, best to reflect fair value.
Debt securities are generally traded in the over-the-counter market and are
valued at a price deemed best to reflect fair value as quoted by dealers who
make markets in these securities or by an independent pricing service.
Investments in mutual funds are valued at the closing net asset value per
share of the mutual fund on the day of valuation.
For purposes of determining the fund's net asset value per share, the U.S.
dollar value of all assets and liabilities initially expressed in foreign
currencies is determined by using the mean of the bid and offer prices of such
currencies against U.S. dollars quoted by a major bank.
Assets and liabilities for which the above valuation procedures are
inappropriate or are deemed not to reflect fair value are stated at fair value
as determined in good faith by or under the supervision of the officers of the
fund, as authorized by the Board of Directors.
Affiliated Companies As defined by the Investment Company Act of
1940, an affiliated company is one in which the fund owns at least 5% of the
outstanding voting securities.

Currency Translation Assets and liabilities are translated into U.S.
dollars at the prevailing exchange rate at the end of the reporting period.
Purchases and sales of securities and income and expenses are translated
into U.S. dollars at the prevailing exchange rate on the dates of such
transactions. The effect of changes in foreign exchange rates on realized
and unrealized security gains and losses is reflected as a component of
such gains and losses.
Premiums and Discounts Premiums and discounts on debt securities are
amortized for both financial reporting and tax purposes.
Other Income and expenses are recorded on the accrual basis. Investment
transactions are accounted for on the trade date. Realized gains and losses
are reported on the identified cost basis. Dividend income and
distributions to shareholders are recorded by the fund on the ex-dividend
date. Income and capital gain distributions are determined in accordance
with federal income tax regulations and may differ from those determined in
accordance with generally accepted accounting principles.
NOTE 2 - INVESTMENT TRANSACTIONS
Purchases and sales of portfolio securities, other than short-term
securities, aggregated $112,816,000 and $122,515,000, respectively, for the
six months ended June 30, 1998.
NOTE 3 - FEDERAL INCOME TAXES
No provision for federal income taxes is required since the fund intends to
continue to qualify as a regulated investment company and distribute all of
its taxable income. At June 30, 1998, the aggregate cost of investments for
federal income tax and financial reporting purposes was $261,773,000, and
net unrealized gain aggregated $38,252,000, of which $50,974,000 related to
appreciated investments and $12,722,000 to depreciated investments.
NOTE 4 - RELATED PARTY TRANSACTIONS

Associates, Inc. (the manager) provides for an annual investment management
19

- --------------------------------------------------------------------------------
fee, of which $163,000 was payable at June 30, 1998. The fee is computed
daily and paid monthly, and consists of an individual fund fee equal to
0.35% of average daily net assets and a group fee. The group fee is based
on the combined assets of certain mutual funds sponsored by the manager or
Rowe Price-Fleming International, Inc. (the group). The group fee rate
ranges from 0.48% for the first $1 billion of assets to 0.30% for assets in
excess of $80 billion. At June 30, 1998, and for the six months then ended,
the effective annual group fee rate was 0.32%. The fund pays a pro-rata
share of the group fee based on the ratio of its net assets to those of the
group.
In addition, the fund has entered into agreements with the manager and two
wholly owned subsidiaries of the manager, pursuant to which the fund
receives certain other services. The manager computes the daily share price
and maintains the financial records of the fund. T. Rowe Price Services,
Inc., is the fund's transfer and dividend disbursing agent and provides
shareholder and administrative services to the fund. T. Rowe Price
Retirement Plan Services, Inc., provides subaccounting and recordkeeping
services for certain retirement accounts invested in the fund. The fund
incurred expenses pursuant to these related party agreements totaling
approximately $454,000 for the six months ended June 30, 1998, of which
$97,000 was payable at period-end.
The fund may invest in the Reserve Investment Fund and Government Reserve
Investment Fund (collectively, the Reserve Funds), open-end management
investment companies managed by T. Rowe Price Associates, Inc. The Reserve
Funds are offered as cash management options only to mutual funds and other
accounts managed by T. Rowe Price and its affiliates and are not available
to the public. The Reserve Funds pay no investment management fees.
Distributions from the Reserve Funds to the fund for the six months ended
June 30, 1998, totaled $350,000 and are reflected as interest income in the
accompanying Statement of Operations.
During the six months ended June 30, 1998, the fund, in the ordinary course
of business, placed security purchase and sale orders aggregating
$3,435,000 with certain affiliates of the manager and paid commissions of
$5,000 related thereto.
