Lond., 1906, v. 22, p. 467. 
NAPHTHALENUM. 
Decker, Adolph, states that naphthalene is used in the form of 
■vapor in the treatment of whooping cough. — X. York M. J., 1906, 
v. 83, p. 767. 
Gair, C. J. Dickinson, outlines a method for the estimation of 
naphthalene in coal gas. — Oil, Paint and Drug Rep., 1906, Jan. 29, 
p. 42. 
Thomann, J., (Schweiz. Wschr. f. Chem. u. Pharm. XLIY, Xo. 9, 
1906, 131) outlines a method for the detection of naphthalene in 
foods. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 858. 
Lutz, Ad., (trans. Sociedade Scientifica, S. Paulo, 1906) reports 
three cases of chronic poisoning from the inhalation of naphthalene 
fumes. — Biocliem. Centralbl., Leipz., 1906-7, v. 5, p. 700. 
Switzer, L. B., has found a mixture of equal parts of powdered 
sulphur, powdered naphthalene, and insect powder dusted over the 
floor of his kennels useful in ridding his dogs of fleas ; he thinks the 
mixture would be useful against chicken lice and perhaps also on cat- 
tle. — Bull. Pharm., Detroit, 1906, v. 20, p. 173. 
NUX VOMICA. 
The Ph. Brit. Committee of Reference in Pharmacy report on nux 
vomica says the Brussels Conference standard is 2.5 per cent of total 
alkaloid. Revise the assay process, especially if strychnine is to be 
determined separately. The U. S. P. process is quite incorrect. The 
powder should be described microscopically. — Chem. & Drug., Loud., 
1906, v. 69, p. 864. 
Grier, J., suggests that the Ph. Brit, limit the source of nux vomica 
to the “ Bombay ” variety and asserts that in this variety strvchnine 
and brucine are present in about equal proportion. — Pharm. J.,Lond., 
1906. v. 22, p. 238. 
Xelson, Burt E., illustrates and describes the structural character- 
istics found in powdered nux vomica. — Merck's Rep., X. Y., 1906, 
v. 15, p. 130. 
Philipp Roder, Wien, proposes to limit the ash content of nux 
vomica to not more than 3.5 per cent and to require a 70 per cent 
alcohol extract content of 12 per cent. Also outlines a method of 
assay for total alkaloids. — Pharm. Zentralh., 1906, v. 47, p. 523. 
Spiegel, L., discusses the chemistry of the strychnos alkaloids. — 
Biochem. Centralbl.. Leipz., 1906-7, v. 5, p. 159. 
Herder, M., discusses the action of various reagents on the alkaloids 
of nux vomica and the demonstration, by microchemical means, of
