saponification equivalents are not. — Proc. Indiana Pharm. Ass., 1906, 
p. 73. 
Nicorescu, Joan, (Rev., farm. Xo. 8, 1906, pp. 236-210) describes 
the medicinal oils, their preparation, preservation, formation of fatty 
acids, and falsification. The presence of alkaloids is recognized by 
treating with a solution of tartaric acid. — Abstr. in Bull, des sc. 
pharmacol. Par., 1906, v. 13, p. 336. 
Marcille, R., discusses the reactions of Bellier (benzol solution of 
resorcin and nitric acid), of Bishop (action of fresh oil of sesame 
and hydrochloric acid), and of Wiedmann (acetone solution of 
phloroglucin with two or three drops of concentrated sulphuric 
acid) and criticises the work of Hans Kreis. He considers that the 
reaction of Bishop is not characteristic of seed oils alone, but is pro- 
duced in a general way with oxidized fatty matters. — Ann. de chim. 
analyt. Par., 1906, v. 11, pp. 51-53. 
Kreis, Hans, replies that Marcille has fallen into a twofold error 
in that the reaction of Bishop has to do with old sesame oil, and 
Marcille has confounded his (Kreis’s) phloroglucin reaction with a 
very slight modification which IViedmann made in the modus oper- 
ands — Ibid., v. 11, p. 113. 
Marcille savs that he knew the work of Kreis only through the 
translation which appeared in the Rev. internat. des falsif., which 
was probably incomplete or erroneous. — Ibid., v. 11, p. 333. 
Kiilm and Halfpaap discuss the application, use, and shortcomings 
of the Welman reaction for vegetable oils, and point out that the 
valuable feature of this reaction is applicability as a preliminary 
test for the presence of vegetable oils. — Ztschr. f. Unters. d. Nahr. u. 
Genussm., 1906, v. 12, pp. 419—155, 
Sidersky, D., (Indus. Bait. Par., 31, 1906, Xo. 48, pp. 775-776) 
presents in tabular form constants for 28 fats and oils of animal and 
vegetable origin calculated from compiled data. — Exp. Sta. Rec., 
1906, v. 18, p. 609. 
Tolman; L. M., as associate referee on fats and oils, of the Asso- 
ciation of Official Agricultural Chemists, outlines the methods for 
conducting the cold test and the cloud test for fatty oils. — Circ. Bur. 
Chem., U. S. Dept. Agric., 1906, Xo. 27, pp. 6. 
Fish, Erwin L., gives five tables showing his results with the color 
reaction of vegetable oils, color reaction of animal oils, nitric-acid 
color test, and nitric and sulphuric acid color test. — Proc. Xew York 
Pharm. Ass., 1906, pp. 203-205. 
The Secretary of Agriculture has adopted standards for edible 
vegetable oils and fats (circular Xo. 19). — Oil, Paint, and Drug Rep., 
1906, v. 69, Apr. 23, p. 50.
