Lancereaux uses a 2.50 to 3.50 per cent gelatin serum in the treat- 
ment of aneurism : 200 gm. injected every five or six days into the but- 
tock may be administered without trouble, absorption generally com- 
plete in twenty-four hours. — Bull, des sc. pharmacol.. Par.. 1906. v. 13 
(Compt. rend. des. soc. sav. ) p. 209. 
GELATINUM GLYCERINATUM. 
Scatcard. Elmer E.. recommends, as a practical addition to the 
U. S. P. VIII directions for preparing glyeerinated gelatin, that in- 
stead of allowing the mass to cool in the dish, from which it is 
removed with considerable difficulty, it be poured upon glass plates 
slightly coated with liquid petrolatum. After cooling it may be 
removed without difficulty and cut into pieces for preservation in the 
stock bottle. — Am. J. Pharm.. Phila.. 1906. v. 75. p. 119. 
GELSEMIUM. 
Henkel. Alice, mention- Gel semi urn semper cirens (L.) Ait. f.. com- 
monly known as gelsemium. yellow jasmine. Carolina jasmine, and 
wild woodbine, as growing on low ground in woods and thickets from 
eastern Virginia to Florida and Texa-. mostly near the coast. — Bull. 
Bur. Plant. Ind.. U. S. Dept. Agric.. 1906. Xo. 89. p. 32. 
The Ph. Brit. Committee of Reference in Pharmacy suggests that 
for gelsemium root an ash limit is not necessary. — Chem. & Drug.. 
Bond.. 1906. v. 69. p. 863. 
Xaylor. IV. A. H.. in his presidential address. B. P. C.. reviews the 
literature having reference to the chemical examination of g'elsemium. 
and concludes, in consideration of the fact that gelsemium is a power- 
ful drug and that it- activity is due ” almost solely ” to its alka- 
loidal principles, it is a matter of surprise that the United .States 
Pharma copceia has not directed the liquid extract to be standardized, 
the more so as it is commonly obtainable of a definite alkaloidal 
strength. Year Bock of Pharmacy. 1906. pp. 210. 211. (See also 
Pharm. J.. Lond.. 1906. v. 23. p. 75.) 
Francis. John M.. asserts that the alkaloids are easily separated 
and purified, hence would readily lend themselves to physiological 
experimentation. It is worthy of more thorough study than has yet 
been given it. Twelve samples of the cured root gave an average of 
0.43 per cent of alkaloids, highest 0.50 and lowest 0.25 per cent. — 
Bull. Pharm.. Detroit. 1906. v. 20. p. 13. 
Sayre. L. E.. report- a number of experiments to determine the 
alkaloidal content of gelsemium root and rhizome. He has not de- 
vised a satisfactory method of assay as yet. and has not been able to 
separate the two alkaloids alleged to be present. — Proc. Am. Pharm. 
Ass.. 1906. v. 54. pp. 383-385.
