scribed. — Bot. Centralbl. Cassel, 1906, v. 101, p. 162. 
An abstract from a report by Consul-General William H. Michael, 
Calcutta, points out that the Madras government, in India, is oper- 
ating cinchona plantations, the product of which is converted into 
quinine in government factories. The report also includes a number 
of figures showing the amount of bark grown and the value. — Oil, 
Paint, and Drug Kep., 1906, v. TO, Oct. 17, p. 42. 
Howard, David, presents a comprehensive survey of cinchona barks 
and their cultivation at a meeting of the London Section of the 
Society of Chemical Industry. — Brit. & Col. Druggist, Loud., 1906, 
v. 49, p. 29. (See also J. Soc. Chem. Ind., Bond., 1906, v. 25, pp. 
97-99.) 
An editorial notes that David Howard’s fascinating lecture before 
the Society of Chemical Industry, on the history of cinchona and its 
cultivation in the East Indies and elsewhere, was one of those rare 
expositions which can not be adequately reproduced in printing ink. 
A table is given showing the exports of Java bark from 1892 to 1905, 
inclusive, with percentages of quinine sulphate, etc. — Chem. & Drug., 
Bond., 1906, v. 68. p. 53. (For further notes and discussion see Ibid ., 
P- 69.) 
Winkler, Hans, describes the cultivation of cinchona in Java, the 
methods employed both in the cultivation as well as in the collecting 
and preparing for market. — Der Tropenflanzer, 1906, v. 10, pp. 
222-238. 
Busse, Walter, records his observations on the cinchona planta- 
tions of Java and discusses their application to the proposed culti- 
vation of this drug in Kamerun and German East Africa. (From 
Tropenpflanzer, 1906.) — Apoth. Ztg., Berk, 1906, v. 21, p. 93. 
An editorial reviews the prospects of economic success in the 
cultivation of cinchona in Kamerun and German East Africa and 
discusses the climatic conditions that are necessary, for the successful 
cultivation of this plant. — Pharm. Ztg., Berl., 1906, v. 51, p. 362. 
Schneider, Albert, reviews the history of cinchona cultivation and 
the possible cultivation of the drug in California. (Paper read at 
Lewis and Clark Pharm. Congress.) — Western Druggist, 1906, v. 
28, pp. 136-143. 
Planchon, L., points out that the true calisaya bark is but seldom 
seen in the European market and that in place of it a drug known 
as Quinquina de Carthagene fibreaux or Q. de Colombie or Q. fibrosa 
is frequently mistaken for the flat calisaya, “ Calisaya plat." He enu- 
merates the characteristics of the two barks. (From Bulk de pharm. 
du Sud-Est., 1906, p. 509.) — Apoth. Ztg., Berk, 1906, v. 21, p. 1076.
