Hemm. Francis, explains how this may introduce constituents not 
desired. — Proc. Missouri Pharm. Ass., 1906, pp. 107, 59. 
Farr and Wright discuss the preparation of concentrated infusions 
and report a number of experiments made to determine the composi- 
tion of infusions and the most satisfactory process of their produc- 
tion. — Pharm. J., London, 1906, v. 22, pp.- 163-166. 
Taylor, S., deplores the fact that the balance of opinion seems to 
be in favor of the concentrated liquors. He doubts the necessity for 
them, but thinks that if we are to have them, they should be called 
by their right names and should be of uniform composition, to secure 
which they must have official sanction. — Ibid., v. 23, p. 670. 
IODOFORMUM. 
Francis, John M., notes the variation in color and density of dif- 
ferent brands, any of which may meet all reasonable therapeutic de- 
mands. The darker and denser products yield the more ash and 
heavier traces of iodides; the best are the lightest, most yellow col- 
ored and finest powdered. — Bull. Pharm., Detroit, 1906, v. 20. p. 56. 
Eiedel’s Berichte (Berl., 1906, p. 24) points out the variation in the 
melting-point requirement for iodoform and asserts that on slowly 
heating this substance melts regularly at from 115° to 116° C. ; on 
heating more rapidly it requires 120° C. 
Utz outlines a method for the determination of the iodoform con- 
tent. — Apoth. Ztg., Berl., 1906, v. 21, p. 930. 
Schoorl and van den Berg (Pharm. Weekbld., 1906, v. 43) report 
observations on the influence of incandescent gas light on iodoform. 
The dry substance, in white glass, is slightly changed by the libera- 
tion of a trace of free iodine. A 5 per cent alcoholic solution was 
markedly changed both in white as well as dark amber glass.— Chem. 
Centralbl., Berl., 1906, v. 77, p. 696. 
Patch. E. L., reports finding a slight excess of soluble iodides and 
chlorides in iodoform. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 338. 
Helfritz. Iv.. discusses the formula submitted by Blanchi for a 
liquid iodoform and makes several suggestions and modifications. — 
Apoth. Ztg., Berl., 1906, v. 21, pp. 323, 324. 
Kauifeisen, L., asserts that the discoloration of iodoform ointment, 
due to the liberation of free iodine, can be corrected or prevented by 
incorporating a sufficient quantity of sodium hyposulphite with the 
ointment. — Pharm. Ztg., Berl., 1906, v. 51, p. 759. 
A contributor to the “ Therapeutics ” column quotes Prager as 
saying that iodoform should not be used in dusting extensive surfaces 
after burns for fear of poisoning. — J. Am. M. Ass., 1906, v. 47, 
p. 1679. 
Dorrance. George Morris, states that a study of cases of osteo-
