Milliau, M. E., proposes a modification of the test with nitrate of 
silver, which he believes will serve to distinguish cotton seed oil from 
other oils. — Ibid., p. 9. 
An abstract or translation ( from Bull, de la Direction de l’Agricul. 
et du Com. de Tunis) discusses the properties of olive oils produced 
in the several districts of Tunis. The oils produced in the central 
districts congeal readily at low temperatures, and the demargariniza- 
tion of these oils is discussed. — Paint, Oil and Drug Rep., 1905, Aug. 
28, p. 38. 
Richardson and Jaffe discuss the question of olive oils and free 
oleic acid in wool combing, and present tabulated results of analyses 
of various olive oils. — J. Soc. Chem. Ind., Lond., 1905, v. 24, pp. 
534-536. 
Just’s Botanischer Jahresbericht (for 1905, v. 33, part 3, p. 783) 
contains several references to the geographical distribution of the 
olive tree, its cultivation, and the manufacture of olive oil. 
OLEUM PICIS LIQUIDJE. 
Branclel, I. W., gives some account of the production, properties, 
and composition of American pine tar oil and the pine tar oil from 
Finland. — Pharm. Rev., 1905, v. 23, p. 326. 
OLEUM PIMENTO. 
Umney and Bennett point out that the lowering of the range of 
specific gravity is certainly an advantage, for the typical aromatic 
bodies characteristic of oil of pimenta are those with the lower 
specific gravity, although, perhaps, they do not add to its medicinal 
value. All of the tests, as in the case of oil of cloves, for other 
phenol bodies have been omitted. — Pharm. J., Lond., 1905, v. 21, p. 
147. 
OLEUM RICINI. 
Eberle, E. G., mentions Ricinus communis among the medicinal 
plants of Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 305. 
Osborne, Mendel, and Harris review the literature relating to the 
examination of the proteins of the castor bean, and record experi- 
ments conducted to determine the nature of these protein con- 
stituents. — Am. J. Physiol., 1905, v. 14, pp. 258-286. 
Finnemore and Deane review the literature on ricinine, ricin, 
ricinoleic acid, and other fatty acids. They conclude that their 
results show that the purgative action of castor oil is due to the 
fatty acids, but it is not quite clear whether ricinoleic acid has been 
obtained absolutely pure, or that it is the only purging fatty acid in 
the oil ; in any case it appears that there must be other undiscovered 
acids. — Pharm. J., Lond., 1905, v. 21, p. 137.
