327 
cent adulteration. The fault is doubtless in the method of prepara- 
tion, neglect to use the proper quantities of iodine and potassium 
iodide, or incomplete solution of the chemicals. — Rep. Indiana Bd. 
Health, 1906, pp. 385-387. 
Ladd, E. F., points out that in the case of tincture of iodine the 
range of variation has been from 25 to 127 per cent of the official 
standard of the L T . S. P. — Rep. North Dakota Agric. Exper. Sta., 
1906, Part II, p. 36. 
Leach, Albert E., asserts that the quality of tincture of iodine 
as sold to-day in the average drug store is far higher than formerly. 
The worst five cases varied from 12 per cent to 65 per cent of the 
U. S. P. strength; 3 of the samples being below 50 per cent of the 
required strength. — Rep. Massachusetts Bd. Health, 1906, p. 401. 
Blome, TV. H., reports on eleven samples of tincture of iodine, which 
he found, as usual, very variable in iodine content, but constant, in so 
far as it failed to come up to requirements in any case. — Proc. Michi- 
gan Pharm. Ass., 1906, p. 105. 
Swann, Mamie, reports the examination of samples of tincture of 
iodine, 5 c. c. of which required, respectively, 23.4, 27.7, 29.6 c. c. of 
volumetric solution for complete decoloration. — Proc. Kansas Pharm. 
Ass., 1906, p. 37. 
Mims, J. C., reports on 46 samples of tincture of iodine with iodine 
percentages ranging from 2.64 to 8.93 free, from 0.00 to 4.89 combined, 
and from 2.94 to 11.50 total. — Proc. Louisiana Pharm. Ass., 1906, 
p. 62. 
Christianson, Lars, asserts that two samples of tincture of iodine, 
prepared according to the U. S. P. VIII, were assayed by a state 
chemist, who found but 5.98 and 5.83 per cent of iodine.— Bull. Am. 
Pharm. Ass*, 1906, v. 1, p. 318. 
The Inspectors of Pharmacies found tincture of iodine with but 
1.76, 2.73, 4.87, and 4.31 per cent of iodine. — J. de pharm. d'Anvers, 
1906, v. 62, p. 91. 
Chassevant, Allyre, presents a formula for a tincture of iodine 
using chloroform as the solvent, and discusses some of the advantages 
of such a solution. — Bull. Soc. de pharm. de Bordeaux, 1906, v. 46, 
pp. 41-43. 
Burmeister (Centralb. f. Chir. Leipz., v. 33, No. 40) claims that his 
modification of the Claudius technic, using chloroform as a solvent 
for the iodine, affords a means of sterilizing catgut without its subse- 
quently becoming friable. — J. Am. M. Ass., 1907, v. 48, p. 85. 
Goebel, TV. (Centralbl. f. Bact., 1906, v. 42, pp. 86, 176), reports 
observations on the disinfecting properties of Lugol’s solution of 
iodine. He finds that a solution of 0.01 to 0.05 per cent of iodine with 
potassium iodide is an efficient disinfectant and quite devoid of objec- 
tionable properties. — Biochem. Centralbl., Leipz., 1906-7, v. 5, p. 711.
