Item 2.  Acquisition or Disposition of Assets.
         ------------------------------------
    On June 30, 1997, Mallinckrodt Inc. ("Mallinckrodt") closed the
sale of its animal health business to Schering-Plough Corporation
("Schering-Plough").  In this disposition, Mallinckrodt sold the
stock of its existing foreign animal health subsidiaries and the
stock of a domestic corporation formed to hold the United States
animal health assets and liabilities being transferred.  Mallinckrodt
retained certain real property, certain environmental liabilities for
transferred properties, and certain other liabilities, including
liabilities for income taxes and certain employee benefits, including
post-retirement benefits.  The consideration received for the sale
was approximately $400 million in cash based on estimates of debt and
working capital as of June 30, 1997, and is subject to further
adjustment based on a post-closing audit of final debt and working
capital amounts, and the agreement of Schering-Plough to assume
certain lease obligations, which agreement remains subject to third
party consents.  The Company recorded, as of March 31, 1997, an
estimated net after tax loss of $275 million on the transaction.  The
consideration for the sale was determined by arms-length negotiations
between the parties.  There does not exist any material relationship
between Schering-Plough, on the one hand, and Mallinckrodt or any of
its affiliates, any director or officer of Mallinckrodt, or any
associate of any such director or officer, on the other hand.

              period ended March 31, 1997 had the operating
              results and the estimated loss on disposal of the
