Meier. H.. has prepared a strychnine antitoxin by injecting animals 
(rabbits) with slowly increasing doses of strychnine. The serum of 
such animals, when injected into other animals, increased their re- 
sistance to strychnine quite markedly, the immunity lasting from three 
to four days. — Abstr. in Pharm. Ztg.. 1905, v. 50, p. 804. 
Petrow, AY. I., reports a number of observations on the destruction 
of the alkaloids strychnine, caffeine, and atropine in the animal or- 
ganism, and concludes that strychnine is not materially changed by 
the several organs examined. — Biochem. Centralbl., 1905, v. 4, p. 
495 (from a dissertation, St. Petersburg, 1905).

STYRAX. 
Ahrens and Hett (Pharm. Zentralh., v. 45, p. 571) base a test for 
the purity of storax on the ready solubility of the resinous adulter- 
ants in cold petroleum benzin, genuine storax being only very slightly 
soluble. — Analyst, Lond., 1905, v. 30, p. 60. 
The annual report of Philip Rocler, AATen, points out that Ahrens 
gives the acid number of petroleum benzin extract of storax as 
being between 36.6 and 62.9, and the saponification number as being 
between 194.6 and 198.4. Thirteen samples of storax were examined 
and were found to vary in : Acid number from 57.5 to 94.0, saponifi- 
cation number from 180.5 to 200.5, ester number from 86.5 to 134.0. 
The petroleum benzin extract of eight samples was examined and 
found to vary for : Acid number from 31.5 to 101.0, saponification 
number from 180.0 to 202.5, ester number from 80.5 to 162.5. Two 
of the samples were found to be contaminated with resin and re- 
fused. — Pharm. Post, AVien, 1905, v. 38, p. 392. 
SULFHUR. 
Domergue, A. (J. de Pharm. et de Chim., v. 20, pp. 493-499), 
points out that there should be a distinction between flowers of sul- 
phur and sublimed sulphur. The former name should be reserved 
for commercial products giving at least 33 per cent of sulphur in- 
soluble in carbon disulphide at the time of manufacture, while the 
other products of the condensation chamber should be termed sub- 
limed sulphur. — Analyst, Lond., 1905, v. 30, p. 92. 
Lyons, A. B., asserts that in the test for arsenic, instead of dis- 
solving the residue in 100 cc. of HC1 and then testing by
