Sayre, L. E., reports that 9 samples of mercurial ointment examined 
varied from 53.9 to 37.7 per cent of metallic mercury. — Bull. Kansas 
Bd. Health, 1906, v. 2, p. 174. 
Havenhill, L. D., reports two samples containing, respectively, 
33 and 41 per cent of mercury; in neither was the fatty base of 
official quality. — Proc. Kansas Pharm. Ass., 1906, p. 36. 
UNGUENTUM HYDRARGYRI AMMONIATI. 
Morstatt, H., outlines a process for the preparation of the ointment 
of ammoniated mercury, freshly precipitated. — Apoth. Ztg., Berl., 
1906, v. 21, p. 194. 
Caldwell, Paul, suggests that instead of the hydrous wool fat, use 
the anhydrous and take the water (30 per cent) allowed in the hydrous 
and pour it upon the mercury salt and let it stand twenty-four hours. 
After this it may be incorporated with the base in the usual way. — 
Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50. p. 159. 
Eberle, E. G., also suggests the use of wool fat instead of hydrous 
wool fat. Rub the ammoniated mercury with a corresponding 
amount of water, incorporate the wool fat, and finally the white pe- 
trolatum. — Proc. Am. Pharm. Ass., 1906. v. 54. p. 450. 
UNGUENTUM HYDRARGYRI NITRATIS. 
The inspectors of pharmacies report that ointment of mercury ■ 
nitrate, which should be yellow, was usually found to be brown or 
«/ * «/ 
gray, not sufficient care being devoted to its preparation or preserva- 
tion. — J. de pharm. d'Anvers, 1906, v. 62, p. 84. 
Taylor, S., says the balance of opinion is in favor of Squire's proc- 
ess, which yields an ointment with good keeping qualities. — Pharm. 
J., Lond., 1906, v. 23, p. 670. 
UNGUENTUM HYDRARGYRI OXIDI ELAVI. 
Kauffeisen, L., recommends the use of freshly prepared yellow 
oxide of mercury in the preparation of the ointment, but warns 
against replacing the water by washing with alcohol or ether. — 
Pharm. Ztg., Berl., 1906, v. 51, p. 759. 
Schweiszinger, O., discusses the history of the ointment of yellow 
oxide of mercury prepared from freshly precipitated mercuric ox- 
ide. — Pharm. Zentralh., 1906, v. 47, p. 630. 
Fleischer (TTiirttb. med. Korrespbl.) outlines a method for the 
preparation of an ointment of yellow oxide of mercury from the 
freshly precipitated salt. — Ibicl., v. 47, p. 739. 
Taylor. S., says the excellent results yielded by the formula lately 
published by Martindale quite outweigh the extra trouble. In fact, 
this is one of those refinements of pharmacy which might well occupy * 
a whole evening's attention! — Pharm. J., Loud., 1906. v. 23, p. 670.
