appended. Occasional lots of commercial acetone have a “ spe- 
cific gravity _pf 0.790 at 25° C. and begin to boil at 56.5° C. ; ” but 
our experience has been that practically all yield from 20 to 45 per 
cent distilling above 56.5° C. Perhaps the distillers will produce 
an exceptionally pure acetone for pharmacists’ use, but we doubt if 
it will be generally procurable for a long time. — Bull. Pharm., 
Detroit, 1905, v. 19, p. 317. 
Herting, Otto, discusses some of the characteristics of acetone, its 
uses and the tests for purity and identity, also some suggestions as 
to its production. — Deut.-Amer. Apoth. Ztg., N. Y., 1905, v. 26, p. 72. 
Pastureau presents a study of the action of hydrogen peroxide on 
acetone. — J. de pharm. et de chim., Paris., 1905, v. 22, p. 14. 
An abstract discusses the determination of acetone, by the iodo- 
form method, as presented by various authors. — Abstr. J. Soc. Chem. 
Ind. Lond., 1905, v. 24, p. 460. 
Ziegler, J., discusses the official (German) test for acetone and 
believes it to be not alone practical, but also readily applied. — Apoth.

Barth, Franz, discusses the difficulties that are met in testing spirit 
of mustard, of the Ph. Germ., IV, for acetone. — Ibid., p. 758. 
Laserre, A., publishes a preliminary report of a study of the action 
of aldehydes and of acetone on solutions of mercuric acetate. — J. de

Frommer, Victor (Berl. Klin. Wchnschr., 1905, p. 1008), outlines 
a method for the detection of acetone in urine. To about 10 cc. of 
urine add 1 gm. of potassium hydrate and without waiting for the 
latter to dissoKe add 10 to 12 drops of salicylaldehyde ; heat the 
mixture to about 70° C. and allow to stand. The presence of acetone 
is indicated by a deep purplish zone at the juncture of the two 
fluids. — Apoth.’ Ztg., Berlin, 1905, v. 20, p. 629. 
ACETPHENETIDINUM. 
Herting, Otto, discusses the nomenclature, some of the chemical 
characteristics, and the tests for acetphenetidin. — Deut.-Amer. Apoth. 
Ztg:, K. Y., 1905, v. 26, p. 85. 
An editorial, in discussing the additions to the U. S. P., VIII, says, 
under acetphenetidin : 
No inkling is given either under this head or under the other synthetics intro- 
duced that these preparations are known popularly under other names, and 
while in some cases the chemical description has been shortened there has been 
no attempt to introduce substitutes for the trade names. — Drug Topics, 1905, 
v. 20, p. 195. 
Rosenthaler, L. (from Suedd. "Apoth. Ztg.), points out that with 
Millon’s reagent phenacetin gives an intense violet color that changes
