The committee on adulteration of the X. W. D. A. report receiving 
a communication which says in part : 
TTe have had offered us, during the last year, by a number of brokers, a pow- 
dered aloes, so called, which contained only a trace of aloin. Investigation 
proved this to be an evaporated residue left after the extraction of the aloin 
from commercial aloes. — Paint. Oil aud Drug Rep., 1905, Oct. 6, p. 15. 
The Ph. Hisp.. VII, under the title aloe and the subtitle or synonym 
“Aloe Soccotrina," describes the drug obtained from various species 
of aloes and includes A loe vera Mill., Aloe spicata Thunb., Aloe 
ferox L., Aloe arborescens Mill.. Aloe linguceformis L., and others. 
It also includes sundry tests for solubility, purity, and identity. — 
Farmacopea Oficial Espahola, 1905, p. 45. 
Leger, E., reports a further elaboration of his work on the aloe 
emodins. — J. de pharm. et de chim., Paris, 1905, v. 22, p. 8. 
Tschirch and Hoffbauer report additional studies on some of the 
more uncommon varieties of aloes, particularly of the aloin derived 
from them. — Arch. d. Pliarm., 1905, v. 243, p. 399. 
Tschirch, A., discusses the oxymethylanthraquinone drugs and their 
assay. Tabulated results of experiments with a number of drugs are 
given. — Reprinted in Pharm. J., Lond., 1905, v. 21, p. 249. 
The preceding papers are also abstracted in Proc. Am. Pharm. Ass., 
1905, v. 53, pp. 616-619. 
van Itallie, L. (from Pharm. TTeekbl., 1905, Xo. 27), used the 
method described by Tschirch and Hoffbauer and compares several 
grades of aloes. He finds that Curacao and Aruba aloes are not 
inferior to the Cape aloes, either in resin content or other require- 
ment. — Pharm. Ztg.. Berlin, 1905, v. 50, p. 835. 
Fawsett, T. (Pharm. J. Lond., v. 19, p. 401), discusses the detection 
and differentiation of aloes in compound rhubarb pills. — Abstr. in 
Year Book Pharm., Lond., 1905, p. 227. 
Francis, John M., believes that the use of the aloin in place of 
aloes, whenever permissible, is to be preferred. “ The former may 
now be had of uniform quality, is readily obtainable, and is com- 
paratively economical/’ He further believes that the use of aloin 
would be in keeping with the modern tendency toward concentration 
and small-sized doses.- — Bull. Pharm., Detroit, 1905, v. 19, p. 318. 
TTilbert, M. I., points out that there is no longer any need for the 
continuance of purified aloes as a pharmacopoeial preparation. He 
asserts that it is neither economical nor desirable, and that, as a 
matter of fact, it is not generally used in the making of pharmaeo- 
pceial preparations, as directed. — Proc. Am. Pharm. Ass., 1905, v. 53, 
p. 345. 
ALOINUM. 
Francis, John M., calls attention to the stress that is laid on 
the particular description of Curacao aloin and suggests that if this
