MENTHOL. 
Siedler, P., believes that the Ph. Germ., IY, melting point require- 
ment for menthol (43°) is low; he found it to require 44.5° C. — 
Pharm. Post, Wien, 1905, v. 38, p. 568. 
The experiments recorded by Riedel indicate that the boiling point 
of menthol is approximately 216.65° at ordinary barometric pressures, 
or about 4.65° higher than the boiling point given in the Ph. Germ., 
IY, and in the U. S. P., YIII. — Riedel’s Berichte, Berlin, 1905, p. 46.

shallow cavities by the use of menthol. — Dental Cosmos, Phila., 1905,

MENTHYLIS SALICYLAS. 
Wetterstroem, Theo. D., quotes a large jobber as saying that the 
substitution of synthetic for natural oil of wintergreen “ is the most 
profitable side line in his business.” — Drug. Circ. & Chem. Gaz.,

MORPHINA. 
The Bureau of Plant Industry reports the perfecting, on a labora- 
tory scale, of a method for the extraction of a very high grade of 
crude morphine from the dried tissues of the poppy plant capsule.— 
Ann. Rep. Dept. Agric., 1905, p. 149. 
Firbas, Richard, has studied the action of acacia on morphine, and 
believes that acacia in solution tends to change morphine into oxy- 
morphine. The latter when present in any appreciable quantity, may 
be detected by the use of potassium dichromate. — Apoth. Ztg., Berlin, 
1905, v. 20, p. 1031. 
Reichard, C. (Chem. Ztg., v. 28, p. 1182), reviews the several tests 
and reactions for morphine. — Pharm. Prax., 1905, v. 4, p. 309. 
An abstract (from Pharm. Zentralh., 1905) points out that both 
morphine and codeine give the same color with sulphuric acid and 
formaldehyde. With sulphuric acid and chloral or bromal, however, 
morphine gives a violet, while codeine yields a blue-gray color. When 
both alkaloids are present in a sample, the color is brown-violet.— 
Apothecary, Boston, 1905, v. 17, p. 628.
