manufacturing purposes on even an experimental scale. A few seeds 
of the plant have been got from Ceylon, Madras, and Calcutta, and the 
plants raised from them show at least two distinct types. These types 
will be carefully watched and compared: with each other as regards 
suse, rapidity of growth, and yield of alkaloids.

* 30. The information contained in the enclosure to the paragraph 
under reply regarding the cultivation of the Coca plant for the m 
acture of cocaine in India has been noted. With regard to the letter 
from the Acting Superintendent, Cinchona cultivation in Bengal, 
No. 2EC/I, dated 20th May 1892, it has been ascertained from 
urgeon-General Sir Benjamin Simpson, K.C.I.E., that the fine sample 
of Coea leaves referred to in Dr. Macnamara’s Report of 7th March 1890, 
a copy of which was forwarded to your goren with Military 
(Stores) Department, No. 19, of 10th April 1890, was grown in the 
Meenglas Tea Estate in the Dooars. Itis, haola thought that the 
plant would flourish equally well, and perhaps better, at a lower eleva- 
tion than the Sikkim metre ‘Plantation, and it would appear to be 
desirable to make the experi

CCCLXXX.—CEYLON COCA LEAVES. 
N the Kew Bulletin, 1889, pp. 1-13, an exhaustive account 
aed of the Coca plant, together with some interesting chemical stil 
respecting the yiell of alkaloids obtained from the different sorts under 
cultivation in different parts of the world. It was shown that leaves from 
he Huanuco, Erythroxylon Coca, Lam., the typical plant, yielded the 
ger per-centage of crystallisable cocaine, while the Truxiilo leaves 
from E. Coca, var. novu-granatense, yielded nearly, if not quite, as 
much total cocaine, bnt alarge proportion of it was in an uncrystal- 
lisable form. Under these circumstances, it was suggested that the 
broad-leaved iilo Erythroxylon Coca was better for generai 
cultivation at high altitudes to yield crystallisable cocaine; but that the 
variety novo-granatense, distributed largely from Kew up to 1889, was
