Exhibit 5 (a)
OPINION AND CONSENT OF ROGER A. KELLER
I have examined the Registration Statement on Form S-8 to be filed by
Mallinckrodt Inc. (the "Corporation") with the Securities and Exchange
Commission under the Securities Act of 1933 covering 750,000 additional shares
of Common Stock, par value $1.00 per share, of the Corporation (the "Shares").
I have examined such documents, certificates, records, authorizations and
proceedings and have made such investigations as I have deemed necessary or
appropriate in order to give the opinion expressed herein.
Upon the basis of the foregoing, I am of the opinion that when the Shares
have been duly delivered against payment therefor, as contemplated by the
Investment Plan for Employees of Mallinckrodt Inc., the shares will be legally
issued, fully paid and, except as may be otherwise provided in Section 630 of
the New York Business Corporation Law, non-assessable.
I hereby consent to the filing of this Opinion as an exhibit to the
Registration Statement.

ROGER A. KELLER
