lime method. He prefers the Leger to the Petit method. — Bull. des. 
sc. pharmacol., Par., 1906, v. 13, pp. 419-427. 
Lefeldt, Max., discusses the assay process for opium and opium 
preparations of the Ph. Germ., and suggests that the process of the 
Ph. Germ. Ill be again adopted with the use of ether in place of 
acetic ether directed in that process. — Ber. d. pliarm. Gessellsch., 
Berl., 1906, v. 16, p. 335. 
Lyons, A. B., believes that in the assay for opium the crude mor- 
phine should be directed to be weighed on a pair of counterpoised 
filters, instead of being detached from the filter for weighing. The 
directions for washing are too complicated and in inexperienced 
hands are liable to vitiate results. He prefers the use of morphinated 
water. — Proc. Am. Pliarm. Ass., 1906, v. 54, p. 441. 
Herting, Otto, commends Casparrs method for the assay of opium 
for codeine as being less complicated and less time consuming than 
would appear from the perusal of the method as outlined. (Proc. 
Am. Pharm. Ass., 1904, v. 52, pp. 386-389.) — D.-A. Apoth. Ztg., 
N. Y., 1906-7, v. 27, p. 16. 
Gardner, Hermann, describes and figures a bottle designed to be 
used in the assay of opium. Because of the absence of awkward in- 
terior corners it is thought to facilitate the removal of the precipi- 
tated morphine. — Pharm. J., Lond., 1906, v. 22, p. 548. 
Evans Sons Lescher and Webb report on the examination of 18 lots 
of opium, in which the average morphine content was 11.3 per cent, 
the lowest was 10 per cent, and the highest 12.44 per cent. They out- 
line the method of assay which they use. — Analytical Notes, 1906, 
E., L. & W., Lond., 1907, pp. 25, 26. 
Graham, Willard, reports the assay of 10 cases of opium. The 
moisture present varied from 21.3 to 24.8 per cent, the morphine in 
moist opium varied from 9.07 to 10.79 per cent, and calculated to dry 
opium from 11.85 to 14.05 per cent. — Proc. Pennsylvania Pharm. 
Ass., 1906, p. 157. 
Thaysen, H., records an examination of manipulated opium which 
was found to contain considerable gum (7.52 per cent). While the 
gum opium showed a morphine content of 10.26 per cent, the resulting 
extract only contained 16.965 per cent. — Ber. d. pharm. Gesellsch., 
Berl., 1906, v. 16, p. 276. 
Fernan, Albert, reports that of 6 samples of opium examined 
3 were found deficient in morphine, 6.5, 7, and 8.9 per cent, re- 
spectively. He also asserts that perfectly starch-free opium is seldom 
met with, probably due to the fact that starch or flour is used as a 
dusting powder. — Ztschr. d. allg. osterr. Apoth- Yer., Wien, 1906, 
v. 44, p. 80. 
Taylor, S., hopes that the extract will be presented in the near 
future as a powder, so that it will fall into line with other extracts. — 
Pharm. J., Lond.. 1906, v. 23, p. 669.
