BISMUTHI OXIDUM HYDRATUM N. F. 
Caldwell, Paul, asserts that hydrated bismuth is more easily made 
than the directions would seem to indicate. — Drug. Circ. & Chem. 
Gaz., N. Y., 1906, v. 50, p. 392. 
BISMUTHI SUBCABBONAS. 
Caspari, Charles E., reports on 3 samples of bismuth subcarbonate 
examined — 2 U. S. P. ; 1 contained excess of chloride. — Proc. Mis- 
souri Pharm. Ass., 1906, p. 102. 
The Ph. Brit. Committee of Deference in Pharmacy advises the 
determination of bismuth in official salts as oxide. Bi 2 0 3 =89-91 
per cent. — Chem. & Drug., Loud., 1906, v. 69, p. 863. 
Alcock, F. H., criticises the indefiniteness of the Ph. Brit, require- 
ments and the lack of quantitative test. He suggests a method for 
determining whether much or little nitrates be present in commercial 
samples. — Pharm. J., Lond., 1906, v. 23, p. 319. 
Bennett, C. T., thinks that the indigo method is easily applicable, 
gives good comparative results, and has the advantage of being more 
rapid than the process suggested by Alcock. He describes his 
method. — Ibid ., p. 361. 
BISMUTHI SUBGALLAS. 
In connection with the title bismuthum subgallicum, the Ph. Austr. 
VIII, in a footnote, gives the information that this substance also 
occurs in trade as “ Dermatol.” 
Lefeldt, Max, outlines a method for the preparation of bismuth 
subgallate and suggests such a method for preparing be included in 
the Ph. Germ. — Ber. d. pharm. Gessellsch., Berl., 1906, v. 16, p. 332. 
Caspari, Chas. E., reports I samples examined — 3 U. S. P., 1 con- 
tained chloride and nitrate. — Proc. Missouri Pharm. Ass., 1906, p. 
100 . 
BISMUTHI SUBNITRAS. 
The Ph. Brit. Committee of Reference in Pharmacy report on bis- 
muth subnitrate says the per cent of bismuth should be raised. — 
Chem. & Drug., Lond., 1906, v. 69, p. 863. 
Caspari, Chas. E., reports 26 samples examined — 1 U. S. P., 23 
contained chloride, 1 chloride and ammonium salts, and 1 chloride 
and carbonate. — Proc. Missouri Pharm. Ass., 1906, p. 98. 
Lambert, Alexander, outlines the Fleiner method of treating gastric 
ulcer with bismuth subnitrate. — J, Am. M. Ass,, 1906, v. IT, p. 817.
