OLEUM COPAIBiE. 
Umnej" and Bennett point out that while there is a requirement 
that oil of copaiba should be laevo-gyrate, no limits are given. — 
Pharm. J., Lond., 1905, v. 21, p. 146. 
Schimmel & Co. abstract a paper on gurjun balsam describing 
the method of collecting and the annual yield. The properties and 
uses of gurjun balsam are also enumerated. — Semi- Ann. Rep., Schim- 
mel & Co., 1905, Apr.-May, pp. 48-49. 
Schimmel & Co. enumerate the constants found in a gurjun balsam, 
which had been imported directly from the East Indies. — Ibid., 
Oct.-Nov., p. 39. 
OLEUM CORIANDEI. 
Schimmel & Co. suggest that the scarcity of oil of coriander is 
due to the increased consumption in connection with the chocolate 
industry. — Semi-Ann. Rep., 1905, Apr.-May, p. 26. 
OLEUM EKIGERONTIS. 
Eberle, E. G., mentions Erigeron canadense among the medicinal 
plants of Texas. — Proc. Am. Pharm. Ass., v. 53, 1905, p. 305. 
Rabak, Frank, reports on a study of oils distilled from fresh and 
from freshly dried herb of Erigeron canadense. A comparison of 
the constants of the oils thus obtained shows a decided difference 
in the ester and in the saponification numbers and a less marked 
difference in the acetylization number. — Pharm. Rev., 1905, v. 23, 
p. 81. See also Semi-Ann. Rep., Schimmel & Co., 1905, Oct.-Nov., 
pp. 23-24. 
OLEUM EUCALYPTI. 
Umney and Bennett point out that no particular source for the 
derivation of oil of eucalyptus is given in the TJ. S. P., VIII, and 
express the opinion that 55 per cent of cineol would be a better min- 
imum for an oil for medicinal purposes. — Pharm. J.. Bond., 1905, 
v. 21, p. 146. 
Vanderkleed, Charles E'., examined 4 samples, the best assaying- 
63. 56 per cent cineol (eucalyptol) ; the poorest, 36.3 per cent. The 
latter and one other sample consisting largely of oil of Eucalyptus 
amygdalina , not Eucalyptus globulus.— Proc. Penna. Pharm. Ass., 
1905, p. 54. 
Gane, E. H., reports a sample of oil of eucalyptus which contained 
castor oil. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 187. 
Bennett, C. T., calls attention to extensive adulteration of oil of 
eucalyptus with castor oil, to the amount of from 12 to 20 per cent. 
He points out that these adulterated oils comply with the several 
tests of the Ph. Brit., IV, and enumerates their characteristics. In
