Wilbert, M. I., discusses the origin and history of Sydenham's 
laudanum and points out that, while of English origin, it is prac- 
tically unknown in its original form in English-speaking countries. — 
Proc. Am. Pharm. Ass., 1906, v. 54, pp. 479-481. 
Eliel. Leo. frequently has use for the tinctura opii erocata of the 
Ph. Germ, and thinks a similar preparation should be in the U. S. 
P. — Ibid., v. 54, p. 482. 
Lyons, A. B., belieyes that the use of petroleum benzin in making 
deodorized tincture of opium is objectionable for many reasons. 
Outlines a method for preparing an odorless tincture. — Ibid., v. 54. 
p. 448. 
Francis, John M., asserts that, while the new product is perhaps 
cheaper and good enough for practical purposes, it is not equal to 
the old, as the extraction is not so thorough. He thinks further 
that the purified benzin required by the process is not easily obtain- 
able and recommends a process by which the pharmacist may pre- 
pare his own supply. — Bull. Pliarm., Detroit, 1906, y. 20, p. 142. 
Wippern, Franz, suggests that in the making of the Ph. Germ, 
equivalent of camphorated tincture of opium the pharmacopoeia di- 
rects that tincture of opium be used in place of powdered opium. —

bought in Birmingham says that four out of ten samples of cam- 
phorated tincture of opium examined had been wrongly prepared. —

Dixon, W. E., discusses the yalue of alkaloids as oyer against 
galenicals; using opium as an illustration, he says that while it must 
be standardized so as to contain roughly 10 per cent of morphine, it 
is nevertheless quite variable, owing to the presence of anywhere from 
2 to 10 per cent of narcotine. Opium obtained from Persia and 
India is unsuitable as a drug on account of the large quantity of 
narcotine which it contains. — Brit. Med. J., Lond., 1906, v. 2, p. 1459.
