Executive Vice President and Chief Financial Officer
Becton, Dickinson and Company

Franklin Lakes, NJ 07417

Dear Mr. Considine:

Note 2 of the Notes to Consolidated Financial Statements of Becton, Dickinson
and Company included in its Annual Report to Shareholders, incorporated by
reference in its Annual Report (Form 10-K), for the period ended September 30,
2003 describes a change in the inventory cost method from the last in, first out
("LIFO") method to the first in, first out ("FIFO") method. There are no
authoritative criteria for determining a 'preferable' method based on the
particular circumstances; however, we conclude that such change in the method of
accounting is to an acceptable alternative method which, based on your business
judgment to make this change and for the stated reasons, is preferable in your
circumstances.

Very truly yours,


/s/ Ernst & Young LLP
