Gutzeit’s test, the residue should be reduced with sulphuric acid 
and sulphurous acid, as directed on page 522, U. S. P., VIII. — Proc. 
Am. Pliarm. Ass., 1905, v. 53, p. 260. 
Ceruti (Boll. Chim. Farm., v. 43, p. 421) outlines a test for sul- 
phur by dissolving in aniline, of the boiling point 180-185, precipi- 
tating with acid and weighing. — J. Am. Chem. Soc., 1905, v. 27, 
p. 1345. 
Lunge, G., gives a description of the method developed by Herman 
Frash to extract sulphur from the deeply covered sulphur beds of 
Louisiana and an account of the success that has attended these 
efforts. — Ztsclir. f. angew. Chem., 1905, v. 18, pp. 1009-1010. 
Bolis, A., points out that the expert engineer sent out by the 
Italian Government to study the production of sulphur in the United 
States reports that the sulphur as produced in the State of Louisi- 
ana is almost pure (90 to 98 per cent) and that the cost of production 
is comparatively low. — Chem. Ztg. Cothen., 1905, v. 29, p. 984. 
Hart, Edward, in a review of the problems of industrial chemistry, 
says that the amount of sulphur taken from the Louisiana deposits 
is said to average 16,000 tons per month. Upward of 23,000 tons 
have been taken from a single well. The existence of 40,000,000 tons 
has been proven. — J. Am. Chem. Soc., 1905, v. 27, p. 158. 
Havenliill, L. D., examined 8 samples of precipitated sulphur; 3 
contained nonvolatile matter, from 0.21 to 0.42 per cent, while the 
remaining 5 contained from 37 to 50 per cent of calcium sulphate. — 
Proc. Kansas Pharm. Ass., 1905, p. 92. 
Caspari, Charles E., reports finding one sample of precipitated 
sulphur containing 52 per cent of calcium sulphate — Proc. Missouri 
Pharm. Ass., 1905, p. 76. 
Ryan, J. J., found 4 samples of precipitated sulphur which con- 
tained calcium sulphate varying from 15 to 47.5 per cent; 4 addi- 
tional samples contained traces of calcium chloride. — Proc. Massa- 
chusetts Pharm. Ass., 1905, p. 104. 
SUPPOSITORIA. 
Wilbert, M. I., discusses the official description of suppositories 
and notes the failure to provide for the molding of suppositories by 
cold compression. — Am. J. Pharm., 1905, v. 77, p. 366. 
van der Wielen, P., discusses the making of suppositories and 
related products having oil of theobroma as a base, and the incor- 
poration of water-soluble ingredients.— Pharm. Weekbl., 1905, v. 42, 
pp. 290-291. 
SYRUPUS. 
Alcock, F. H., suggests the addition of a trace of potassium car- 
bonate (1 grain to 12 ounces of the finished product) to the Ph. Brit.
