Erythroxylon Coca grown in India.* 



Several samples of Erythroxylon Coca leaves, grown in various 

 districts in India, have been examined by Warden ; the mode of 

 culture, altitude, and meteorological characters of the district, the 

 kind of soil and manuring, and the methods of curing being taken 

 into consideration. The alkaloid was estimated by Squibb's modified 

 method : the dry pulverized leaves were moistened with alcohol 

 acidified with sulphuric acid, percolated with alcohol, the percolate 

 mixed with acidified water, and extracted with ether, then rendered 

 alkaline with sodium carbonate, and again extracted with ether. This 

 extract was washed twice with water, dried and weighed ; the 

 amounts of *' crude alkaloid" so determined are given in the follow- 

 ing table :
