EMULSUM PHOSPHATICUM N. F. 
Caldwell, Paul, suggests the desirability of devising a formula that 
will yield a permanent phosphatic emulsion. — Drug. Circ. & Chem. 
Gaz., N. Y., 1906, v. 50, p. 393. 
EPINEPHRINA. 
The Council on Pharmacy and Chemistry describes a number of 
commercial suprarenal preparations. — J. Am. M. Ass., 1906, v. 47, 
p. 857. 
Maben, Thomas, thinks the statement of the Ph. Belg. Ill that 
the active principle of the suprarenal gland is not yet defined from 
a chemical point of view is somewhat surprising considering that 
Aldrich, Pauly, Jowett, and other workers are all agreed as to the 
constitution of the principle. He declares that the quantitative test 
prescribed in the Ph. Belg. Ill is an official recognition for the first 
time of the principle of physiological standardization. — Chem. & 
Drug., Bond., 1906, v. 69, p. 155. 
Friedmann, E., briefly describes the work on the constitution of 
adrenalin and accepts the formula C 9 H 13 N0 3 , proposed by Aldrich, 
as being the correct one. He discusses at some length the probable 
constitution of the adrenalin molecule. — Beitr. z. chem. Phys. u. 
Path., Brnschwg., 1906, v. 8, pp. 94-120. 
Farner, A., in a review of the progress of pharmaceutical chemistry, 
points out that the composition of the active principle of the supra- 
renal gland is being gradually cleared up and that the body 
C 9 H 13 N0 3 appears to be a derivative of pyrocatechin. — Schweiz. 
Wchnschr. f. Chem. u. Pharm., 1906, v. 44, p. 617. 
An abstract from U. S. P. patent No. 829220 outlines a method for 
the separation of the active principle from suprarenal glands. — Chem. 
Repert., Cothen, 1906, v. 30, p. 303. 
Vanderkleed, Charles E., outlines a method for the preparation of 
solutions of the active principle of the suprarenal gland, reviews the 
contributions on the subject from the time of Vulpian (1856) to the 
present, and gives in detail the method of preparing and standard- 
izing the resulting solutions. — Proc. Am. Pharm. Ass., 1906, v. 54, 
p. 388. 
“ Gnomon,” commenting on Vanderkleed’s paper, says it may be 
permissible that extracts of the suprarenal gland should vary in ap- 
pearance, but anything which is claimed to be the active principle 
of the gland, and of definite composition, should hardly differ to 
such an extent as do adrenalin, suprarenalin, and other kindred sub- 
stances. A standard is certainly needed in this case, as much as in 
the case of strychnine or morphine. — Pharm. J., Bond., 1906, v. 23, 
p. 698.
