senega, ipecacuanha, jaborandi, quassia, calumba, manna, and cin- 
chona. — Farmacopea Oficial Espanola, 1905, pp. 355-359. 
Zeisler deprecates the fact that even some of the leading manufac- 
turers of fluid extracts in the country print on their labels formulas 
for the preparation of infusions from fluid extracts and believes that 
the practice should be discouraged. — Drug. Circ. & Chem. Gaz., N. Y., 
1905, v. 49, p. 319. 
IODOFORMUM. 
Siedler, P., points out that the Ph. Germ., IV, requires that iodo- 
form have a melting point of about 120° C., and that under normal 
conditions it was found to melt at from 115° to 116° ; on more rapid 
heating it is possible to reach 120° before the material melts. — Pharm. 
Post, Wien, 1905, v. 38, p. 568. 
Utz (Pharm. Zentralh., v. 45, pp. 985-987) outlines a method for 
the determination of iodoform, in which the iodoform is directed to 
be dissolved in a mixture of ether and methyl alcohol, treated with a 
few drops of fuming nitric acid and T V N. silver nitrate, the mix- 
ture heated, diluted, and finally- titrated with ammonium thiocyanate 
solution. — Abstr. in J. Soc. Chem. Ind., Lond., 1905, v. 24, p. 353. 
A somewhat similar process by M. Borri is noted in Bull, des Sc. 
Pharmacol., 1905, v. 12, p. 19. 
Schoorl and van den Berg discuss the changes that are brought 
about in iodoform under the influence of light, heat, and air. They 
enumerate the decomposition products and record some experiments 
carried out to determine the probable changes. — Ber. d. x pharm. 
Gesellsch., Berlin, 1905, v. 15, p. 398. 
van Aubel, E. (Plrys. Ztg. v. 5, p. 637), discusses the decomposition 
of iodoform by the combined action of light and oxygen. This de- 
composition takes place even in non-fluid mixtures (e. g., iodoform 
and vaseline) under the action of light, Rontgen rays, or of radium 
emanations. — J. Soc. Chem. Ind., Bond., 1905, v. 24, p. 103. 
Stevens, Luther F., outlines a method for the preparation of iodo- 
form by the interaction of acetone and potassium iodide in the pres- 
ence of sodium hydrate and solution of chlorinated soda. — Proc. New 
York Pharm. Ass., 1905, pp. 92-94. 
Rousch, G. A., discusses the electrolytic production of iodoform 
from acetone and points out that the electrolysis of potassium iodide 
and acetone without a diaphragm produces 2 molecules of alkali 
for each molecule of iodoform produced, whilst with a diaphragm 
4 molecules of acid are obtained to each molecule of iodoform. He 
proposes a combination of the two reactions (from Proc. Am. Elec- 
trochem. Soc., 1905). — J. Soc. Chem. Ind., Lond., 1905, v. 24, p. 1254. 
Blanchi, A., recommends an extemporaneous preparation of iodo- 
form prepared by mixing the following ingredients in the order
