Item 1.   Security and Issuer
          This Amendment No. 9 to Schedule 13D on the Common Stock
of Church & Dwight Co., Inc. (the "Issuer") is being filed on
behalf of the undersigned to amend the Schedule 13D, as amended
(the "Schedule 13D") which was originally filed on December 17,
1993.  Unless otherwise indicated, all capitalized terms used
herein but not defined herein shall have the same meaning as set
forth in the Schedule 13D.

Item 2.   Identity and Background
          This statement is being filed by Mario J. Gabelli ("Mario
Gabelli"), Marc J. Gabelli ("Marc Gabelli") and various entities
which either one directly or indirectly controls or for which
either one acts as chief investment officer.  These entities,
except for Lynch Corporation ("Lynch"), Spinnaker Industries,
Incorporated ("Spinnaker"), Western New Mexico Telephone Company
("Western New Mexico"), Entoleter, Inc. ("Entoleter"),  Lynch
Telecommunications Corporation ("Lynch Telecom"), Lynch Telephone
Corporation ("Lynch Telephone") and Inter-Community Telephone
Company ("Inter-Community") (collectively, "Lynch and its affili-
ates"), engage in various aspects of the securities business,
primarily as investment adviser to various institutional and
individual clients, including registered investment companies and
pension plans, as broker/dealer and as general partner of various
private investment partnerships.  Certain of these entities may
also make investments for their own accounts.
          The foregoing persons in the aggregate often own
beneficially more than 5% of a class of equity securities of a
particular issuer.  Although several of the foregoing persons are
treated as institutional investors for purposes of reporting their
beneficial ownership on the short-form Schedule 13G, the holdings
of those who do not qualify as institutional investors may exceed
the 1% threshold presented for filing on Schedule 13G or implemen-
tation of their investment philosophy may from time to time require
action which could be viewed as not completely passive.  In order
to avoid any question as to whether their beneficial ownership is
being reported on the proper form and in order to provide greater
investment flexibility and administrative uniformity, these persons
have decided to file their beneficial ownership reports on the more
detailed Schedule 13D form rather than on the short-form Schedule
13G and thereby to provide more expansive disclosure than may be
necessary.
          (a), (b) and (c) - This statement is being filed by one
or more of the following persons: Gabelli Funds, Inc. ("GFI"),
Gabelli Asset Management Inc. ("GAMI") , Gabelli Funds, LLC

Plan (the "Plan"), Gabelli International Limited ("GIL"), Gabelli
International II Limited ("GIL II"), Gabelli International Gold
Fund Limited ("GIGFL"), ALCE Partners, L.P. ("ALCE"), Gabelli

204A of the Advisers Act, respectively.  They further agreed to
each pay a civil penalty in the amount of $50,000, and to retain,
