was unable to verify with oils which he had reason to believe were 
genuine. He states that while the two oils have the same constitu- 
tion. the oil of gaultheria of commerce is oil of black birch. — Bull. 
Pharm. Detroit, 1906, v. 20, p. 141. 
Lakey, R. H., quotes a correspondent, who asserts that oil of 
wintergreen from wintergreen leaves is obtainable, but the supply is 
small and the demand is small. The article actually supplied when oil 
distilled from wintergreen leaves is ordered is an oil of birch. — Proc. 
Pennsylvania Pharm. Ass., 1906, p. 117. 
Schinnnel & Co., assert that oil of wintergreen is frequently found 
to have a reddish color, owing to traces of iron. — Semi-Ann. Kep., 
1906, Apr.-May, p. 77. 
Price and Engle (Am. J. Med. Sci.) report a fatal case of poison- 
ing by oil of wintergreen in a 2-year-old chihL — Jahresb. u. Tier.

Francis, John M., comments on the difficulty of obtaining a fine 
grade of sweet, bleached cotton seed oil and on the lack of knowledge 
of its value in pharmacy and of the variation in quality of the various 
brands. He advises the purchaser to specify “ winter white " or 
bleached oil and to criticise the color and odor very sharply. — Bull. 
Pharm., Detroit, 1906, v. 20, p. 141. 
Schwartz, David, describes the cotton seed oil industry of the 
South, the method of making the oil, and the uses to which it is 
put. — J. Am. Chem. Soc., 1906, v. 28, pp. 430—433. 
An editorial reviews the economic conditions prevailing in the 
cotton seed oil market and presents a table giving high and low quota- 
tions for this oil during the past three years. — Oil, Paint-, and Drug 
Rep., 1906, v. 70, Xov. 26, p. 7. 
Kuhn and Bengen make a contribution to the knowledge of the 
Halpen reaction for cotton seed oil, discuss the varying conditions 
under which the reaction fails, and point out that in the examination 
of land suspected of being adulterated with cotton seed oil it is ad- 
visable to use the phytostearin acetate test. — Ztschr. f. Unters. d. 
Xahr. u. Genussm., 1906, v. 12, pp. 145-153. 
Petlow, X. (Ztsclir. offentl. Chem., 13, 1907, Xo. 2, pp. 21-25), 
reports studies of the Halphen and Becchi reactions, and asserts that 
the two reactions are believed not to be dependent upon the same sub- 
stance, but that the two tests are considered necessary in determining 
the presence of cotton seed oil, inasmuch as certain samples do not 
respond equally well to both tests. — Exper. Sta. Rec., 1906, v. 18, 
p. 709. 
Smith, Kline & French Co. report the results of the examination of 
10 samples of cotton seed oil. — Lab. Rep. S., K. & F., 1906, p. 16.
