UNGUENTUM HYDRAEGYRI OXIDI RUBRI. 
Kauffeisen, L., asserts that for the production of a satisfactory, 
nonirritating ointment of red oxide of mercury the most satisfactory 
procedure is continued rubbing to insure complete and even incor- 
poration of the active ingredient with the ointment base. — Pliarm. 
Ztg., Berl., 1906, v. 51, p, 759. 
UN GUENTUM RESORCINI COMPOSITUM N. F. 
Caldwell, Paul, discusses the technique of making compound resor- 
cin ointment and suggests that the resorcin be added to the melted 
paraffin and petrolatum before adding these to the remainder of the 
ointment. — Drug. Circ. & Chem. Gaz., N. Y., 1906, v. 50, p. 393. 
Schellentrager and Mulhan present a somewhat modified formula 
for this ointment, together with a method for its preparation. — Proc. 
Ohio Pliarm. Ass., 1906, p. 47. 
UNGUENTUM SULPHURIS COMPOSITUM N. F. 
An abstract proposes the following modification for making Wil- 
kinson's ointment : Lard 6 and tallow 6 are melted together in a 
suitable vessel and this mixture then added to a hot, previously 
melted portion of soft soap 12. The resulting mixture is allowed to 
cool somewhat, and the prepared chalk 1, sublimed sulphur 2, are 
gradually added, with constant stirring. Finally, when nearly cool, 
tar 6 is added. — Pharm. Ztg., Berl., 1906, v. 51, p. 30. 
UNGUENTUM ZINCI OXJDUM. 
MacFadden, W. Lester, in commenting upon the disadvantages of 
lard, says it would seem that inasmuch as the action of zinc oint- 
ment is soothing and protective the use of petrolatum as a base were 
a step ahead. — Bull. Pharm., Detroit, 1906, v. 20, p. 204. 
The inspectors of pharmacies point out that while the ointment 
of zinc oxide is widely used it is rarely made in compliance with the 
requirements of the pharmacopoeia. — J. de pharm. d'Anvers, 1906, 
v. 62, p. 84. 
Cruse, E., asserts that the official, Ph. Germ. IV ointment of zinc 
oxide, made with lard, does not keep well, and suggests a base con- 
sisting of a mixture of glycerin, lanolin, and paraffin ointment. — 
Pharm. Ztg., Berl., 1906, v. 51, p. 906. 
UVA URSI. 
Henkel, Alice, mentions Arctostaphylos uva-ursi (L.) Spreng., com- 
monly known as uva-ursi, bearberry, and upland cranberry, as 
a native of rocky or dry, sandy soils from the Middle Atlantic States
