Item 1.               Security and Issuer.
                      -------------------

             The class of equity  securities to which this Statement  relates is
the common  stock,  no par value (the  "Common  Stock"),  of  BioTime,  Inc.,  a
California  corporation  (the  "Company"),  which  has its  principal  executive
offices at 935 Pardee Street, Berkeley, California 94710.


Item 2.               Identity and Background.
                      -----------------------

             This  Statement is being filed in connection  with the Common Stock
beneficially  held by  Spinnaker  Technology  Fund,  L.P.,  a  Delaware  limited
partnership  ("Spinnaker").   Spinnaker  conducts  its  principal  business  and
maintains  its  principal  office at 22 Gatehouse  Road,  Stamford,  Connecticut
06902.

             The  sole  general   partner  of   Spinnaker  is  SoundView   Asset
Management,  Inc.,  a Delaware  corporation  ("SoundView"),  which  conducts its
principal  business and  maintains its  principal  office at 22 Gatehouse  Road,
Stamford,  Connecticut  06902.  All business of Spinnaker is conducted under the
complete and  exclusive  control of  SoundView.  (Spinnaker  and  SoundView  are
sometimes hereinafter referred to as the "Filers").

             Spinnaker  was  formed  in  1994  for  the  principal  business  of
providing  an  investment  vehicle  for  institutional  and other  sophisticated
investors to acquire equity  interests in companies with  significant  potential
for long-term growth in value in the technology  industry.  SoundView was formed
in 1994 for the principal business of serving as the general partner and manager
of various investment funds and portfolios.

             The  name,  business  address,   present  principal  occupation  or
employment of each  executive  officer and director of SoundView is set forth in
Schedule  I  hereto,  which is  incorporated  herein by  reference.  Each of the
individuals listed in Schedule I hereto are U.S. citizens.

             During  the past  five  years,  none of the  Filers  nor any of the
executive  officers  or  directors  of the  Filers (i) has been  convicted  in a
criminal proceeding (excluding traffic violations or similar  misdemeanors),  or
(ii) was a party to a civil proceeding of a judicial or  administrative  body of
competent jurisdiction and, as a result of such proceeding, was or is subject to
a judgment, decree or final order enjoining future violations of, or prohibiting
or mandating  activities subject to, federal or state securities laws or finding
any violation with respect to such laws.

Item 3.               Source and Amount of Funds or Other Consideration.
                      -------------------------------------------------

             The funds used by Spinnaker in making the  purchases of  additional
shares of Common  Stock,  as set forth in Item 5, in the  amount of  $562,115.50
were obtained from the capital contributions made by its partners.


Item 4.               Purpose of Transaction.
                      ----------------------

             The Filers have acquired the Common Stock for investment  purposes.
None of the Filers has any  intention  of  acquiring  control  over the Company;
however,  if  Spinnaker or SoundView  believe  that  further  investment  in the
Company is attractive,  whether  because of the market price of the Common Stock
or otherwise,  they may acquire  additional  shares of Common Stock.  Similarly,
depending upon market and other factors,  the Filers may determine to dispose of
the Common Stock. Except as disclosed above, the Filers do not have any plans or
proposals  of the type set  forth in  Paragraphs  (a)  through  (j) of Item 4 of
Schedule 13D.


Item 5.               Interest in Securities of the Issuer.
                      ------------------------------------

             (a) and (b) The  number  of  shares  of  Common  Stock  issued  and
outstanding and the percentage  calculations  resulting therefrom in this Item 5
are based on  information  contained in the Company's  most  recently  available
filing with the Securities and Exchange Commission. According to the Company, as
of February 9, 1996,  there were  2,591,014  shares of Common  Stock  issued and
outstanding.

             Spinnaker   beneficially  owns  192,300  shares  of  Common  Stock,
representing  approximately  7.4% of the Common  Stock  issued and  outstanding.
Spinnaker has sole voting and dispositive power with respect to all Common Stock
owned by it, which power is exercised by its general partner, SoundView.

             SoundView  may be  deemed  to  beneficially  own all the  shares of
Common Stock owned by Spinnaker by virtue of its status as sole general  partner
of Spinnaker.  Such deemed  beneficial  ownership  would total  192,300  shares,
representing  approximately  7.4% of the Common  Stock  issued and  outstanding.
SoundView may be deemed in its capacity as general partner of Spinnaker to share
the voting power and the power to direct the disposition of the shares of Common
Stock owned by  Spinnaker.  SoundView  disclaims  beneficial  ownership  of such
shares.

April 24                        25,000                      17.2197

             (d) To the best  knowledge of the Filers,  no person other than the
Filers has the right to receive or the power to direct the receipt of  dividends
from, or the proceeds from, the sale of shares of Common Stock.

             (e)  Not applicable.
