Ivinyon. H. E., believes that sluggish bowel movement, either from 
a nervous or muscular atony, may be cured by either nux vomica, 
strychnine, or arsenicum. — Hahnemann. Month., Phila., 1905, v. 10, 
p. 795. 
OLEORESINA. 
Francis. John M., points out that in the preparation of most offi- 
cial oleoresins acetone now replaces ether, and while it is admitted 
to combine the solvent properties of both alcohol and of ether, he 
believes that the resulting preparations may prove unsatisfactory 
because of the tendency to separate into a heavy portion correspond- 
ing to an alcoholic extract insoluble in ether and a lighter portion 
corresponding in a measure to the usual ether-extracted oleoresin, 
more or less insoluble in alcohol. — Bull. Pharm.. Detroit, 1905, v. 
19, p. 316. 
OLEA. 
FIXED OILS. 
Schindler, J. (Ztschr. f. Enters. Xahr. u. Genussm., v. 9, p. 738), 
asserts that petroleum spirit (boiling between 30° and 15° C.) is pre- 
ferred to ether for the determination of oil in seeds. He gives the 
yield of oil from 10 different seeds. — Pharm J.. Lond., 1905, v. 21, 
p. 443. 
Rakusin, M. (Apoth. Ztg.. v. 20. p. 528). has determined the flash 
point of some vegetable oils. A table embodying his results is repub- 
lished in the abstract. — Merck's Rep., X. Y., 1905, v. 7, p. 280. 
Schroeder, August, reports some experimental work with several 
more or less rare oils and fats, including the oil from Strychnos mix 
vomica , He vea brasilliensis Muller, and Poly gala senega L. — Arch. d. 
Pharm!, 1905, v. 243. p. 628. 
An abstract (from La Revue de Chimie Industrielle) discusses the 
bleaching and concentration of vegetable oils. — Paint, Oil and Drug 
Rep., 1905, Aug. 21, p. 42. 
TTinckel. Max. discusses the decomposition of fats and the causa- 
tion of rancidity. From his own experiments, and from a review of 
the literature, he concludes that the rancidity of fats is primarily due 
to the decomposition of the fatty acids under the influence of light 
and air.— Apoth. Ztg.. Berlin, 1905, v. 20, p. 690. 
Telle, Fernand ( J. de Pharm. et de Chim., Paris, 1905, p. 180), con- 
siders the determination of the bromine number of fats as being more 
reliable than the corresponding determination of the iodine number. 
Unfortunately the great volatility of bromine and the corresponding 
variability of the solutions containing it are difficult to overcome.— 
Pharm. Zentralh., 1905, v. 46, p. 686.
