Bettendorf's reagent for arsenic, will yield an immediate black 
deposit of metallic antimony, and the supernatant liquid — if As is ab- 
sent — appears colorless. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 850. 
The Pli. Brit. Committee of Reference in Pharmacy reports on 
tartrated antimony. Alcock’s test also applies here. (See Antimonii 
oxidum.) — Chem. & Drug., Loud., 1906, v. 69, p. 862. 
Tocher, J. F., says the effect of an alkaline cobalt solution of 
tartar emetic adds weight to the belief that this compound is not 
strictly a tartrate; its high rotatory power, its cryoscopic value, and 
other considerations tend to prove that it is a tartra-antimoniate of 
potassium. — Pharm. J., Bond., 1906, v. 23, p. 87. 
Duncan, J. B., outlines a modification of Xisseuson and Siedlein’s 
method for the volumetric estimation of antimony. — Chem. Eng., 
Phila., 1906-7, v. 5, pp. 265-267. 
Darroch, James, outlines a modified iodine method for the volu- 
metric estimation of antimony, using a standard solution of stannous 
chloride in place of the solution of sodium thiosulphate ordinarily 
employed. — Ibid ., v. 4, pp. 162-165. 
St. John, D. (J. Med. Soc., X. J., Xewark, Sept.), “ Value of tartar 
emetic in the treatment of traumatic tetanus and cerebrospinal menin- 
gitis." — J. Am. Ass., 1906, v. 47, p. 1139.

Havard, F. T.. discusses the economic conditions regulating the 
production of antimony, the new uses for antimony, and the several 
processes employed in the production of metallic antimony. — Chem. 
Eng., Phila., 1906-7, v. 5, pp. 140-145. 
The Ph. Brit. Committee of Reference in Pharmacy points out that 
few samples of antimonium oxide pass the cream of tartar test. Al- 
cock’s method (dissolving in hydrochloric acid in the cold with the 
addition of Rochelle salt and excess of sodium bicarbonate before 
titrating with standard iodine solution) is preferable. Also applies 
to antimony and potassium tartrate. — Chem. & Drug., Loud., 1906, 
v. 69, p. 862, 
Coblentz, Virgil, says that little, if any, antimonium oxide is made 
in this country. Analysis would indicate that the samples, although 
from distant sources in this country, were obtained from the same 
parties abroad. It evidently consists of a mixture of various anti- 
monic acids, is of little medicinal use, and, since no standards could 
be drafted with which it might possibly comply, it is better out of 
the pharmacopoeia than in it. — Am. J. Pharm., Phila., 1906, v. 78, 
p. 392. 
Arny, H. V., thinks the omission of sulphurated antimony was 
unnecessary, as it is a very popular expectorant among French physi- 
cians of the South. — Am. J. Pharm., Phila., 1906, v. 78, p. 11.
