essential oils is only applicable to oils which are simple mixtures of 
phenols and terpenes. — Analyst, London, 1905, v. 30. p. 62. 
Wallach and Kohler discuss the constitution of eucarvone and its 
reduction products, and point out that von Baeyer’s formula for 
eucarvone is not in accord with several properties of the compound. —

A communication from U. S. Consul-General Skinner. Marseille, 
France, gives some account of the methods that are in use in Southern 
France for the production of essential oils and pomades. The article 
refers specifically to the production of the so-called oil of geranium. — 
Western Druggist, Chicago. 1905, v. 27, pp. 80-81. 
Just’s Botanischer Jahresbericht (for 1905. v. 33, part 3, pp. 787- 
788) contains a number of references that are of interest in connection 
with the general subject of essential oils. 
Metzel, Richard, presents a contribution to the study of the phar- 
macologic properties of terpenes and terpene derivatives. — Arch, 
internat. de Pharmacod. et de Therap., 1905, v. 14, pp. 351-354. 
OLEUM AMYGDALAE AMARiE, 
L T mney and Bennett point out that the specific gravity of oil of 
bitter almond has been lowered from 1.060 to 1.070 at 15° C. to 1.045 
to 1.060 at 25° C., which is a reduction more than proportionate to 
the different temperatures at which the determination is now made. 
In discussing the benzaldeliyde determination they point out that the 
small quantity of oil required to be used is rather disadvantageous, 
and their results rather lead them to believe that the ordinary alde- 
hyde absorption process, as used for the determination of cinnamic 
aldehyde in cassia oil, is preferable.— Pharm. J., Lond., 1905, v. 21, 
p. 145. 
Liickner, Ed., reports autoxvdation in a sample of oil of bitter 
almond that had been carefulh 7 preserved and securely corked.- — 
Apoth. Ztg.. Berlin, 1905, v. 20. p. 1044. 
An abstract (from Pharm. Ztg., 1905, v. 50, p. 177) discusses the 
preparation of bitter almond water of the Ph. Germ., IV, and points 
out that maceration of the press cake should not be prolonged beyond 
six hours as the yield of HCX is lessened; the distillation requires 
one and one-half to two hours. — Proe. Am. Pharm. Ass., 1905, v. 53, 
p. 521. 
An abstract (from Brit. Med. J., Lond.) reports a case of poison- 
ing by bitter almond oil. — Drug Circ. & Chem. Gaz., 1905, v. 49, 
p. 229. 
OLEUM AMYGDALA EXPRESSUM. 
Wetterstroem, Theo. D., asserts that oil of peach kernel is exten- 
sively sold as oil of sweet almond. — Drug. Circ. & Chem. Gaz., 1905,
