This statement is the second amendment to the statement
on Schedule 13D filed on November 30, 1993 with the Securities
and Exchange Commission by Corning Incorporated in connection
with its beneficial ownership of shares of common stock, par
value $.01 per share (the "Common Stock") of MDL Information
Systems, Inc. (the "Issuer").
Item 5. Interest in Securities of the Issuer.
Item 5 is hereby amended by deleting the material
therein and substituting the following new material:
(a) Corning, for purposes of the federal securities
laws, is presently the beneficial owner of 488,000 shares of
the Common Stock of the Issuer having sold 192,000 shares on
the open market on December 26, 1995. To the best knowledge
of Corning, none of the persons listed in Schedule I
beneficially owned on the date hereof any shares of the
Issuer's Common Stock. Based on the number of shares of the
Issuer's Common Stock outstanding as of December 26, 1995,
(8,350,000, according to the Issuer), 488,000 shares of the
Issuer's Common Stock constitutes approximately 5.8% of the
outstanding shares of the Issuer's Common Stock.
(b) Corning has the sole power to vote and to dispose
of the shares of the Issuer's Common Stock set forth in
Paragraph (a) above.
(c) Except as set forth in paragraph (a) above, no
transactions in the Common Stock of the Issuer were effected
during the past 60 days by Corning or, to the best of the
knowledge of Corning, any of the persons listed on Schedule
I hereto.
(d) None
(e) Not applicable.
