pp. 921-923. With additional details of methods and resnlts, and 
several charts. — Ztschr. f. anorgan. Chem., 1905, v. 14, pp. 209-220. 
The annual report by Philip Roder, Wien, points out that zinc 
chloride is sometimes met with which does not comply with the 
solubility requirement. — Pharm. Post, Wien, 1905, v. 38. p. 393. 
Copeland, Royal S., suggests a 1:500 solution of zinc chloride in 
water as being useful in the treatment of pink-eye. — Hahnemam 
Month., Phila., 1905, p. 318. 
McClintic, T. B., reviews the literature relating to the properties 
and uses of zinc chloride, and discusses the possible uses of this com- 
pound as a deodorant, an antiseptic, and a germicide. He concludes 
that, while zinc chloride has some properties as a deodorant to recom- 
mend it favorably, its antiseptic and germicidal powers are compara- 
tively feeble, and this fact, with its cost and caustic properties, practi- 
cally exclude it from the useful and reliable disinfectants. — Bull. Xo. 
22, Hyg. Lab. U. S. P. H. & M.-H. S., Wash., 1905, p. 24. 
ZINCI OXIDUM. 
The committee on adulteration points out that zinc oxide is quite 
often found to contain chlorides and sulphates, and occasionally 
iron. — Proc. Michigan Pharm. Ass., 1905, p. 79. 
The annual report by Philip Roder, Wien, indicates that lead is a 
frequent contamination of zinc oxide. Of three samples examined, 
two were refused because of their lead content, which was demon- 
strated bv a process suggested by Gliickmann : Dissolving the zinc 
oxide in acetic acid and treating this with potassium clichromate. — 
Pharm. Post, Wien, 1905, v. 38, p. 393. 
Bascoveseo (Rept. de Pharm., 1905, p. 212) suggests the use of zinc 
oxide as a reagent for various salts. He records the reaction obtained 
with mercuric chloride, mercurous nitrate, mercuric nitrate, acid bis- 
muth nitrate, cuprous chloride, the chrome salts, ferric salts, ferrous 
salts, and aluminum salts, and concludes that zinc oxide is a suitable 
reagent to aid in the separation of copper from cadmium, and of iron 
from manganese. — Pharm. Zentralh., 1905, p. 651; also Drug. Circ. & 
Chem. Gaz., 1905, v. 49, p. 239. 
ZINCI SULPHAS. 
The annual report of Philip Roder, Wien, says that of five samples 
of zinc sulphate examined, three were found to be contaminated with 
iron and aluminum. — Pharm. Post, Wien, 1905, v. 38, p. 393. 
Burkett, E. W. (in Mines and Minerals), outlines the methods em- 
ployed for determining zinc, iron. lead, lime, and silicate in zinc ores, 
in the Joplin district, Missouri. — Chem. Eng., 1905, v. 3, pp. 40-44.
