or about 5 per cent higher than the figures given by Heisch and 
Zipperer. — Ztschr. f. Unters. Nar. u. Genussm., 1905, v. 9, p. 377. 
An abstract from a monthly summary, Department of Commerce 
and Labor, contains an account of the history, description, cultiva- 
tion, curing, and preparing of the several varieties of cacao. — Pharm. 
Era., N. Y., 1905, v. 34, p. 508. 
An abstract (from Bull, des Sc. Pharmacol., Paris, 1905, p. 302) 
presents an enumeration of the countries producing and of the coun- 
tries using cacao and the amount, in metric tons, that is produced and 
used. The annual consumption, 64,507 tons, in 1894, has been 
increased to 127,452 tons in 1903. — Schweiz. Wchnschr. f. Chem. u. 
Pharm., 1905, v. 43, p. 386. 
OLEUM THYMI. 
Umney and Bennett suggest that oil of thynft, might also find a 
place in a new Ph. Brit., and point out that the proportion of thymol 
and carvacrol (the two phenols) vary considerably in different sam- 
ples of the oil, and especially in the samples of the closely allied 
origanum oils imported from eastern Europe. — Pharm. J., Bond., 
1905, v. 21, p. 148. 
Schimmel & Co. discuss the priority of the suggestion of the use of 
soda lye for phenol determination in essential oils. Controverting 
the claims that are made by Umney, they assert that the method was 
first recommended by Gildemeister, in 1892, for the phenol deter- 
mination in thyme oil. — Semi-Ann. Rep., Schimmel & Co., 1905, 
Apr. -May, p. 76. 
Schimmel & Co. record some adulterations found in oil of thyme. 
One sample adulterated with oil of turpentine was particularly strik- 
ing on account of its deficient solubility and low phenol content, 12.5 
per cent; not soluble in 10 volumes of 80 per cent alcohol. Another 
sample was designated as “ white ” thyme oil, and had probably been 
mixed with a considerable quantity of camphor oil. — Ibid., Oct- 
Nov., p. 67. 
OLEUM TIGLII. 
Lloyd, John Uri, asserts that probably no one is in a position to say 
positively that he has ever used any croton oil pressed wholly from 
the seed of Croton tiglii , though he is not willing to assert that the 
oil in a state of absolute purity can not be obtained. — Pharm. Rev., 
1905, v. 23, p. 300. 
Mazzuchelli (Arch. Farmac. sperim., 1905, p. 223) says that, con- 
trary to the assertion of various authors, petroleum benzin does 
dissolve castor oil, and that this fact can be utilized for the purpose 
of detecting croton oil when mixed with castor oil. — Am. Druggist, 
N. Y., 1905, v. 47, p. 202.
