Zinc Ointment.—Our attention has been directed to the following
remarks of Dr. Copland, Part xvi. of his Dictionary of Practical Medi-
cine, p. 935, on the subject of zinc ointment:—
“ Great care should be taken in this affection, as well as in others for
which ointments may be required, that they be recently made. In a case
to which I was lately called, the zinc ointment was prescribed after the
use of emollient applications, and was found quite rancid and most in-
jurious at five different Chemists in the outskirts of the town where it
was had; but when this ointment was procured from a respectable Chemist
in town, it was quite successful.’’
To guard against a recurrence of this accident, we would suggest that
where the demand is small, it would be better not to keep the oint-
ment ready, but to mix it when wanted.—Lond. Pharm. Jour. January,
1853.
