SODII BROMIDUM. 
Wiebelitz, H., suggests the same modifications for the tests for 
sodium bromide and sodium iodide that he proposes for the corre- 
sponding salts of potassium. — Pharm. Ztg., Berl., 1906, v. 51, p. 1004. 
Ziegler, J., asserts that the pure, anhydrous sodium bromide is 
freely soluble in 9 parts of alcohol and that the salt containing water 
of crystallization is soluble in 5 parts of alcohol. — Apoth. Ztg., Berl., 
1906," v. 21, p. 911. 
Gane, E. H., reports sodium bromide as being 97, 97.1, and 98.8 
per cent pure. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 346. 
Ohliger, Willard, reports sodium bromide containing an excess 
of alkali. — Proc. Michigan Pharm. Ass., 1906, p. 48. 
Caspari, Charles E., reports 4 samples examined — 2 U. S. P. ; 2 
contained excess of chloride. — Proc. Missouri Pharm. Ass., 1906, 
p. 99. 
Fernan, Albert, found a sample of sodium bromide containing 
23.6 per cent of water. — Ztschr. d. allg. oesterr. Apoth. -Ver., Wien, 
1906, v. 44. p. 79. 
y. Wyss, H., reports observations and experiments made to deter- 
mine the behavior of the bromide salts in the human and animal 
organism. — Arch. f. exper. Path. u. Pharmakol., 1906, v. 55, pp. 
263-287. 
References on the use of sodium bromide will be found in the 
Index Medicus, the J. Am. M. Ass., and Merck’s Ann. Rep. 
SODII CARBONAS MONOHYDRATUS. 
Kohut, Adolph, presents a sketch of Nicolas Leblanc, the founder 
of the soda industry, points out the advance that has been made in 
the science as well as in the practical application of chemistry as the 
result of the work done by Leblanc, and also calls attention to the 
lack of recognition given him. — Pharm. Ztg., Berl., 1906, v. 51, pp. 
39, 40. 
Jurisch, Konrad W., presents some practical observations on the 
ammonia soda industry as developed in Germany, England, France, 
and Austria. — Chem. Ztg., Cothen, 1906, v. 30, pp. 681-683, 719-721, 
799, 800, 821-823, 880, 881, 905-907, 1143-1145, 1170-1173. 
Francis, John M.. in commenting on the notable instability of the 
three salts — the normal crystalline, the exsiccated, and the monohy- 
drated — says it is fair to presume that chemical manufacturers will 
make provision to meet the demand for the official salt. — Bull. 
Pharm., Detroit, 1906, v. 20, p. 186. 
The Ph. Brit. Committee of Reference in Pharmacy believes that 
| for exsiccated sodium carbonate it is necessary to allow a limit of 
water. — Chem. & Drug., Lond., 1906, v. 69, p. 865.
