stalk contains 0'49 per cent., the leaf 0-9 per cent., and the seed oapsnle 0*585 
per cent, of alkaloid. 
Previous to the outbreak of the present war not only was a large propor- 
tion of the drug grown in Germany but German chemists practically held a 
monopoly for the manufacture of the alkaloid. 
If then the supply of this substance falls short of the demand, English 
manufacturing chemists can obtain an adequate supply of the raw material 
from Northern India, for the plant can be exported in the dry state without 
impairing its value for alkaloidal manufacture.— J. H. Barnes.) The Agricul- 
tural Journal of India, January, 1916 pp. 86-88.
