                   SECOND SUPPLEMENT TO PROXY STATEMENT
			 ------------------------------------

                                FOR THE
                   2002 ANNUAL MEETING OF STOCKHOLDERS
                    TO BE HELD ON NOVEMBER 18, 2002


	The Proxy Statement, dated October 9, 2002, as supplemented by the
Supplement to Proxy Statement, dated November 1, 2002, each previously
furnished to stockholders of Scientific Industries, Inc. (the "Company")
for the solicitation by the Board of Directors of proxies to be voted at
the Annual Meeting of Stockholders of the Company to be held at the
Princeton Club, 15 West 43rd Street, New York, New York 10036 on Monday,
November 18, 2002 at 10:30 A.M. (New York Time) is hereby supplemented
further as follows:

Voting Information

	"Broker non-votes" with respect to a particular matter are shares
held in street name that are not voted on the matter because either no
instructions are given by the beneficial owner as to how to vote the
shares or the broker is not permitted under applicable rules because
of the subject matter of the proposal to vote such shares, but whose
shares are present on at least one matter.  Such shares will be deemed
present in determining a quorum but, in the view of the Company, they
should not be counted as voting on each proposal at this Meeting;
accordingly, they will not have any effect on any of the proposals
presented to the stockholders at this Meeting.  As stated in the
Proxy Statement as supplemented, the vote required to approve the
proposals to approve the 2002 Stock Option Plan, the ratification of
the independent auditors and the Kleiman Stockholder Proposal, is, in
each case, the affirmative vote of the holders of a majority of the
votes cast.  There is uncertainty regarding the manner in which we
intend to calculate such votes under the Company's Bylaws and
Delaware law.

Proxy Cards

	You should have received the WHITE proxy card (the "Original
Proxy Card") which accompanied the Proxy Statement dated October 9, 2002
and a second WHITE proxy card (the "Second Proxy Card") which accompanied
the Supplement to Proxy Statement dated November 1, 2002.  Another copy
of the Second Proxy Card is enclosed herewith.  The Original Proxy Card
did not include any reference to the Kleiman Stockholder Proposal.
Please note that consistent with Delaware law:

	If you have not returned the Original Proxy Card, please discard it.
If you have previously returned the Original Proxy Card and have not
returned the Second Proxy Card, you will have given the Company's
Board of Directors' designated proxy holders discretion to vote your
shares against the Kleiman Stockholder Proposal and that is all you
need to do if you support your Board's recommendation. If you wish to
specify the manner in which your shares are to be voted on any of the
proposals (including the Kleiman Stockholder Proposal), you should mark,
sign, date and return either the Second Proxy Card or the accompanying
WHITE proxy card.  If you have not returned either the Original Proxy
Card or the Second Proxy Card, we encourage you to sign, date and
return the enclosed proxy card and return it in the enclosed
self-addressed postage pre-paid envelope.
