with the methods of preparation, taken from the several London. 
Dublin. Edinburgh, and British pharmacopoeias and the U. S. P., 
1870. — Pharm. J., Loud., 1906, v. 23, p. 694. 
FERRI SULPHAS. 
Ohliger, Willard, reports ferrous sulphate with traces of free acid, 
which required about twice the proper amount of water to effect 
solution. — Proc. Michigan Pharm. Ass., 1906, p. 47. 
FERRI SULPHAS EXSICCATUS. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
exsiccated ferrous sulphate says either omit temperature for drying 
or say 100° to 110° C. — Chem. & Drug., Bond., 1906, v. 69, p. 863. 
Patch, E. L., reports on 3 samples of exsiccated ferrous sulphate: 
88.43, 84.85, 84.5 per cent. — Proc. Am. Pharm. Ass., 1906, v. 54, 
p. 338. 
FERRUM. 
Liicker, Ed., discusses the pulverization of metallic iron and de- 
scribes the method adopted in a mill devoted to the production of 
powdered iron. — Apotli. Ztg., Berk, 1906, v. 21, p. 271. 
FERRUM. 
SCALE SALTS. 
Arnv, H. V., regrets the omission of the process of making scale 
salts of iron. If the manufacture of ferric citrate was deemed too 
intricate for the retailer, the Committee on Revision could have at 
least retained the recipes for those scale salts made from the citrate, 
and especially those containing alkaloids, it being well known that 
many of the preparations found in commerce are deficient in 
strength.— Am. J. Pharm., Phila., 1906, v. 78, p. 13. 
FERRI ET AMMONII CITRAS. 
Caspari, Chas. E., reports two samples of iron and ammonium 
citrate examined : One U. S. P., one contained excess of iron. — Proc. 
Missouri Pharm. Ass., 1906, p. 101. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
iron and ammonium citrate says the U. S. P. iodometric determina- 
tion of iron is preferable to the Pli. Brit, method. — Chem. & Drug., 
Bond., 1906, v. 69, p. 863. 
Shurly, B. R., advises the use of iron and ammonium citrate 
hypodermically in anaemia of the pre-tubercular stage. — J. Am. M. 
Ass., 1906, v. 46, p. 1835.
