OLEUM CARYOPHYLLI. 
Umney and Bennett assert that — 
It lias been shown that the strength of alkaline hydroxide solution used for 
absorption of the phenols makes some little difference in the percentage re- 
corded (see Year Book of Pharmacy, 1903, p. 64), and our experience shows that 
the difference in absorption of phenols, using 5 and 10 per cent solutions of 
caustic potash, is 84 per cent in the former case and 89 in the latter, where the 
combined eugenol is entirely decomposed.” — Pliarin. J., Loud., 1905, v. 21, p. 145. 
Riedel thinks the requirement in the Ph. Germ., IV (also in the 
U. S. P., VIII), that eugenol should have a boiling point varying 
from 250° to 253° is too low. The figures given by Hoffman, 250° to 
260°, are thought to be more nearly correct. — Riedel’s Berichte, 
Berlin, 1905, p. 49. 
Schimmel & Co. think it advisable to judge of the value of clove 
oil according to its eugenol content, particularly as the refractive 
index alone can not be taken as a standard of the eugenol content. — 
Schimmel &' Co., 1905, Apr.-May, p. 24. 
Yanderkleed, Charles E., reports that three samples of oil of cloves 
all assayed above 73 per cent of eugenol. — Proc. Pennsylvania 
Pharm. Ass., 1905, p. 54. 
The British vice-consul in Pemba reports that the yield of the 
clove harvest in 1904 reached the exceptional height of 14,447,600 
pounds against 5,552,700 pounds in 1903, and 7,462,300 pounds in 
1902.— Semi-Ann. Rep., Schimmel & Co., 1905, Oct.-Nov., p. 20. 
Frankforter and Lando discuss eugenol and certain of its deriva- 
tives. — J. Am. Chem. Soc., 1905, v. 27, p. 641. 
Schimmel & Co. describe “ Caryophyllin ” as being a crystallizable 
substance which is present in the closed flower buds of the clove, 
Caryophyllus aromaticus L. It is said to have the composition 
Ci 0 H 16 O. Meyer and Honigschmid (Monatsch. f. Chemie, v. 26, 
p. 379) record a detailed examination of this substance, and conclude 
that the proper molecular formula would be four times the formula 
disclosed by the analysis. — Semi- Ann. Rep., Schimmel & Co., 1905, 
Oct.-Nov. , pp. 20-22. 
OLEUM CHEUOPODII. 
Eberle, E. G., mentions Chenopodium antlielminticum among the 
medicinal plants of Texas.— Proc. Am. Pharm. Ass., 1905, v. 53, 
p. 304. 
The Bureau of Plant Industry reports the successful cultivation 
of American wormseed ( Chenopodium antlielminticum) ; the ex- 
perimental plat yielding at the rate of somewhat over 1,000 pounds 
per acre. — Ann. Rep. U. S. Dept. Agric., 1905, p. 148.
