    activity to be clue to a body containing cannabinol—a red, oily, or resinous fluid very prone to oxidation {Pharm. Jonni. [4j, XV., pp. 131, 171, 263, 284).

Specimens of the extremely expensive cassia bark used by the Chinese, but not exported to this country, presented by a former student, Mr. H. Humphreys, of Hong Kong, to this Museum, were sent for examination, together with other unnamed varieties of cassia, to Dr. Pfister, of Munich, and other specimens subsequently to Prof. Hartwich, of Zurich, when these pharma- cognosists were investigating the histological characters of the different commercial varieties of cinnamon. Dr. Piaster's observations were published in 1893 [Zur Kemitnus dcr Xintiii- trinden, E. Wolff, Munich), and those of Prof. Hartwich in the Archir. dcr Phaniiacic, 1901. So far as these results concern the specimens from this Museum, an abstract is here given. Dr. Pfister reports as follows :— (1) The high-priced thick-coated cassia barks received from Mr. Humphreys are derived from C. Cassia, D.C. See also p. 51, 54. (2) The Cassia rcra from Padang, and the cassia from Timor, and the Cinnamon Kiamis bark are the produce of ('. Biiniianni, D.C. Some of the cinnamon of Japan in the Museum of the Society is probably derived from C. Loiircirii, Nees.

Nees, and Eberm., although the structure bears some resemblance to that of C. Zci/Ianimm. (4) Cinuaiiioiiniiii oJitiisifoIitoii, Nees, is the source of the cassia bark in the collection of Indian drugs in the Society's Museum, and of a hard cassia bark from Calcutta, Mus. Cat., 1878, p. 112, No. 452e, f/ioi thmhtfidln rcfern-d to C. Taiiiala. Besides the ordinary cassia barks, several allied barks were reported on by Dr. Pfister, viz.:— (5) C.
