Zernik, F., points out that the content of free iodine in Jod vasoli- 
ment was 1.25 per cent while iodine vasogen was practically free 
from free iodine. The total iodine content in iodine vasogen was 
demonstrated to be 5.96 per cent. — Arb. a. d. pharm. Inst., d. Univers.,

PETROLATUM SAPONATUM SPISSUM N. F. 
An article in Notes and Queries points out some of the precau- 
tions to be exercised in the making of solid petrox, N. F., and the 
need for using ingredients that are of U. S. P. standard. — Drug. 
Circ. & Chem. Gaz., N. Y., 1906, v. 50, p. 443. 
PHENOL. 
Schieffelin, Wm. Jay, is quoted as pointing out that while a sample 
of phenol may crystallize at 40° C. when the test is first applied, 
the same sample, upon repeating the test, will drop a degree; for this 
reason a certain degree of latitude should be allowed in this test. — 
Am. Druggist, N. Y., 1906, v. 49, p. 347. 
Wippern, Franz, points out that it is practically impossible to 
prevent the acquisition of a reddish tint by phenol, on standing, and 
that, once discolored, there is no known method by which it can 
readily be decolorized. He suggests that the Ph. Germ., in the com- 
ing revision, permit of a slight reddening on standing. — Pharm. Ztg., 
Berl., 1906, v. 51, p. 805. 
A report on the drug market presents a compilation of the high 
and low prices for phenol prevailing during 1901 to 1905, inclusive. — 
Oil, Paint, and Drug Rep., 1906, v. 69, Jan. 29, part 2, p. 33. 
Kebler, Lyman F., reports that a sample of “ Carbolic acid, pure 
crystals,” was found to be a brownish black ; an extremely poor qual- 
ity. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 348. 
An abstract (Pharm. Zentralh.) points out the variation in the 
composition of phenol camphor, also known as Chlumsky’s solution, 
and recommends 1 part of phenol, 2 parts of camphor, and a small 
proportion of alcohol. — J. d. Pharm. v. Elsass-Lothr., 1906, v. 33, p. 
257. 
Lemberger, Ignaz, reviews some of the literature relating to the 
production and use of mixtures of phenol and camphor. Also 
records some experiments made to determine the properties of the 
mixture. — Therap. d. Gegenw., Berl., 1906, v. 47, pp. 215-217. 
Caldwell, Paul, points out that the public demand is for a stronger 
ointment, and that the ointment is insufficient in consistence, and 
suggests the addition of from 5 to 10 per cent of paraffin to the white 
petrolatum which constitutes the base of the 1900 ointment. — Drug. 
Circ. & Chem. Gaz., N. Y., 1906, v. 50, pp. 159-160.
