alkaloid. I am still occupied with researches to find out the real nature of this amorphous alkaloid. . . . The remaining 
alkaloids, which were not dissolved by ether, proved to be cinchonine , with only a trace of cinchonidine. In this root, as 
in the former, I found the cinchonine particularly fit to crystallize, and consequently I obtained beautiful sulphate of cinchonine 
from it.

For the guidance of the Indian Government, I send the foregoing interesting and well-executed analysis, and add that it 
accords most nearly with the previous analyses by Dr. de Vrij and myself of No. 2 Root Bark of larger size, but of the same 
parcel, and that these specimens of root bark would command but a low price in the London market, from the causes before 
tated. I do not think the root bark of this species would repay cultivation.
