tion of chromic acid. If the phenacetin is pure the solution assumes a ruby red 
color, which is permanent. If it contains acetanilide the solution assumes a 
dark green tint, and later a deposit is observed. — Abstr. Am. Druggist, N. Y.,

A report of a subcommittee of the council on pharmacy and chem- 
istry of the American Medical Association gives the percentage pro- 
portion of acetanilide, caffeine, and sodium bicarbonate in each of 
several of the more widely advertised acetanilide mixtures. Diluents 
and other constituents than those mentioned in the report were not 
determined. The substances reported on, and their percentage con- 
tent of the substances mentioned, were (J. Am. M. Ass., Chicago, 
1905, v. 44, p. 1790) : 
Ammonol . — Acetanilide, 50 ; sodium bicarbonate, 25 ; ammonium carbonate, 20. 
Antikamnia. — Acetanilide, 68; caffeine, 5; citric acid, 5; sodium bicarbon- 
ate, 20. 
Phenalgin. — Acetanilide, 57 ; sodium bicarbonate, 29 ; ammonium carbonate, 10. 
SaJacetin. — Acetanilide, 43 ; sodium bicarbonate, 21 ; sodium salicylate, 20. 
Kohler's Headache Poioder. — Acetanilide, 76; caffeine, 22. 
Orangeine.— Acetanilide, 43 ; sodium bicarbonate, 18 ; caffeine, 10.

ACETONUM. 
Hinriehs, Carl G., says: 
From old Roger Bacon till to-day is a long cry ; bis spirit bas just been made 
official. Acetone is an excellent solvent fer organic as well as inorganic com- 
pounds. especially mercuric salts. It is a good addition to tbe U. S. P. —

Francis, John M., points out that the specification of 99 per cent 
pure acetone demands a grade not easily procurable, and furthermore 
such purity is not guaranteed by the other specifications and tests
