Dear Sirs:
In connection with the public offering of shares of
beneficial interest, $.01 par value, of Dean Witter Health
Sciences Trust (the "Trust"), I have examined such corporate
records and documents and have made such further investigation
and examination as I have deemed necessary for the purpose of
this opinion.
It is my opinion, as Legal Counsel for the Trust, that the
Trust is an unincorporated business trust duly organized and
validly existing under the laws of the State of Massachusetts and
that the shares of beneficial interest covered by the Rule 24f-2
Notice, September 11, 1997 (File No. 33-48189 and 811-6683), were
issued and paid for in accordance with the terms of the offering,
as set forth in the prospectus filed as part of the Registration
Statement, as amended, of the Trust and were legally issued,
fully
paid and non-assessable by the Trust.
I hereby consent to the filing of this opinion as an exhibit
to the Notice pursuant to Rule 24f-2. In giving this consent, I
do not thereby admit that I am within the category of persons
whose consent is required under Section 7 of the Securities Act
of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.
Very truly yours,
Barry Fink
Vice President
And General Counsel
