Singapore pepper that had been coated with a mixture of flour, 
chalk, and umber so as to increase its size and weight. (From Bol- 
lett. Chimic. Farmaceut., 1906.) — Apoth. Ztg., Berl., 1906, v. 21, 
p. 796. 
Teyxeira and Bimbi (Bull. Chim. Farm., 1906, pp. 68, 69) recently 
found in the market a natural pepper falsified by the addition of 
powdered marble. A second sample (Ibicl., 188, 189) was adulterated 
.with farinaceous and collagenous materials. — Abstr. in Bull. des. sc. 
pharmacol. Par., 1906, v. 13, pp. 518-520. 
Truffi, Ferruccio, reports the examination of an adulterated black 
pepper. — Bull. chim. farm. Milan, 1906, v. 45, pp. 521-528. 
PIX LIQUIDA. 
Caldwell, Paul, asserts that the formula for glycerite of tar is a 
very unsatisfactory one and suggests the addition of potassium car- 
bonate. He also points out that wine of tar does not keep well, 
because there is not enough alcohol in the formula. Stronger white 
wine contains from 20 to 25 per cent of alcohol, but it is necessary 
to have 50 per cent of alcohol in order to insure the permanency of 
the preparation. — Drug. Cir. & Chem. Gaz., X. Y., 1906, v. 50, p. 393. 
Gottheil, William S., states that he has found tar externally as use- 
ful as chrysarobin in the treatment of psoriasis. — J. Am. M. Ass., 
1906, v. 47, p. 1637. 
PLUMBUM. 
Mayer, O., describes a method for the volumetric estimation of lead, 
which depends on the precipitation of the lead with an excess of 
volumetric solution of potassium chromate and determination of the 
excess of chromate by the iodometric method. — Pharm. Ztg., Berl., 
1906, v. 51, p. 299. 
White, John, presents a study of two complex salts of lead con- 
taining chlorine. 
White & Xelson also present a study of the reactions involved in the 
formation of certain complex salts of lead. — Am. Chem., J., 1906, 
v. 35, ppfi2 v l7-227, 227-235. 
Quellien, Paul, (These de Paris, 1905, Xo. 151, p. 48) shows that 
saturnism is accompanied by increased blood pressure. With the in- 
crease of the disease the blood pressure rises. — Abstr. in Biochem, 
Centralbl., Leipz., 1906-7, v. 5, p. 133. 
Simon and Spillman discuss the alterations in the blood in experi- 
mental saturnism. — Compt. rend. Soc. de biol., Par., 1906, v. 60, p. 765. 
Deleaide and Dubois (Presse Med. Par., v. 14, Xo. 13, 1906) discuss 
saturnine intoxication and its treatment. — J. Am. M. Ass., 1906, v. 46,
