Zinci oxidi, sj ; acidi oleici, 5j; vaselini, ^ix. M. The oxide of zinc is to be rubbed up with the oleic acid and allowed to stand for about two hours. The mixture is then placed in a water bath until the oxide of zinc is dissolved, when the vase- line is added and the mixture is stirred until cold. If we have the oleate already prepared, the following formula is a good one : R. Zinci oleat., sj; vaselini, ung. aq. rosse, aa §ss. M. Diseases of the Ear, etc.—Oleate of zinc is recommended by H.

John Marshall, Demonstrator of Chemistry in the University of Penn- sylvania (F/ii7a. Med. News, October 29, 1887), showed that it was a fraudulent mixture of atropine and cocaine.
