BISMUTHI SUBSALICYLAS. 
The Ph. Brit. Committee of Reference in Pharmacy report on bis- 
muth salicylate says the U. S. P. test for the free salicylic acid is 
better. Five grammes treated with 30 cc. purified ether should 
yield not more than 3 mgms. of salicylic acid. — Chem. & Drug., 
Bond., 1906, v. 69, p. 863. 
BISMUTHUM. 
A news item asserts that an increase of nearly 400 per cent in the 
production of bismuth ore in 1905 is recorded in the Annual Report 
of the U. S. Geological Survey, prepared by G. C. Schnatterbeck. — 
Oil, Paint and Drug Rep., 1906, v. 70, Sept. 10, p. 54. 
Aloy and Frebault present the results of their researches relative 
to the halogen salts and the oxides of bismuth. — Bull. Soc. de chirn., 
Par., 1906, v. 35, pp. 396-400. 
Hollard and Bertiaux (Pharm. J., July 8, 1905, 33; from Ann. 
de chim. anal., 1905, 10, 11) outline an electrolytic process for the 
determination of bismuth. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 
851. 
BOROGLY CERINUM N. F. 
Caldwell, Paul, asserts that it is not possible for the pharmacist 
to make boroglyceride, N. F. Ill, unless he possesses a vacuum pan ; 
otherwise the heat can not be regulated so as to keep the finished 
product from assuming a dark brown color. — Drug. Circ. & Chem. 
Gaz., N. Y., 1906. v. 50, p. 392. 
BROMOFORMUM. 
Schoorl and van den Berg report observations on the effect of 
incandescent gas light on bromoform. In brown vials bromoform 
remained unchanged; in white glass it liberated free bromine and 
gave an acid reaction due to the formation of hydrobromic acid 
(from Pharm. Weekbld., 1906, v. 43). — Chem. Centralbl., Berl., 1906, 
v. 77, p. 696. 
Caspari, Chas. E., reports 2 samples examined. — 1 acid, 1 contained 
bromide. — Proc. Missouri Pharm. Ass., 1906, p. 102. 
BROMUM. 
Coblentz, Virgil, says that various samples of German bromine 
assayed 99 per cent, while that of Michigan origin was 98.5 per cent. 
Bromine from Western Pennsylvania and Ohio contained from 6 to 
12 per cent of chlorine. Considering the quality of American bro- 
mine, it was deemed advisable not to raise the standard of the bro-
