Evans Sons Lescher and Webb assert that of eight samples of 
cubeb offered to them, two were of the “ macy type and gave a 
yellowish brown color with sulphuric acid. They believe this sim- 
ple test is of very great value, but agree that a fixed standard for 
oleoresin is also to be recommended. — Analytical Notes for 1906, 
190T, p. IT. 
La Wall, Charles H., explains why alcohol is preferred to acetone 
or ether in the extraction of the oleoresin ; the latter, while extracting 
a larger proportion of the oleoresin, gives a turbid product. — Proc. 
New Jersey Pharm. Ass., 1906, p. 72. 
Smith, F. A. Upshur, points out that in the U. S. P. oil of cubeb 
is directed to be protected from light, while the oleoresin is not 
given the same consideration. — Pharm. J., Lond., 1906, v. 22, p. 33. 
An editorial reviews the market conditions relating to cubeb and 
gives figures showing the prevailing prices during 1902-1906. — Oil, 
Paint and Drug. Pep., 1906. v. TO, Sept. 3, p. T. 
CUPRI SULPHAS. 
Kebler. Lyman F., reports copper sulphate containing iron in 
appreciable quantities. — Proc. Am. Pharm. Ass., 1906, v. 54. p. 348. 
Pead, Ezra L., discusses the estimation of copper by titanium 
trichloride. — J. Chem. Soc., Lond.. 1906, v. 89. pt. 2, pp. 1491-1495. 
An editorial discusses the claims made for the efficiency of copper 
sulphate as a purifier of water for drinking purposes. — J. Am. M. 
Ass., 1906, v. 46, p. 513. 
Clark and Gage (from J. Infect. Dis., Chicago, February, 1906) 
point out the danger of depending on the use of copper sulphate or 
the storing of water in copper vessels, and conclude that very dilute 
solutions of copper sulphate or of colloidal copper may have a de- 
cided invigorating effect on bacterial activity. — Ibid., v. 46, p. 915. 
Tovonaga, M., (Bull. Coll. Agric., Tokyo, 1906, v. 7, pp. 25-28) 
reports that rabbits were kept for eight months with copper car- 
bonate given in the food (2 gm. in all) without showing any signs 
of copper poisoning. — Abstr. in Biochem. Centralbl. Leipz., 1906-7, 
v. 5, p. 247. 
Moulden, W. R., (Med. Rec. X. Y., July 28) thinks that copper 
sulphate shows a more or less selective action on the Amceba coli, 
hence that it is useful in the treatment of intestinal amoebiasis. — 
J. Am. M. Ass., 1906, v. 47, p. 458. 
Stevens, J. F., (Western Med. Rev., Lincoln, Nov.) included the 
use of copper by the mouth and flushing of the colon by solution of 
copper sulphate with other measures in the treatment of typhoid 
fever. — Ibid., v. 47, p. 2122,
