Sir,—In continuation of my letter of the 17 th instant, I have the 
honour to inform you that I have this day forwarded by banghy a por- 
tion of the bark belonging to sample No. 3, which, unfortunately by an 
oversight, was omitted to be packed; this makes the total weight of 
dry bark of No. 3 specimen 33 tolas, viz. 18% tolas previously for- 
warded, aud 14$ tolas now submitted; and will feel obliged by your 
having the goodness to correct the list accordingly. 
Report of an Analysis of the Third Remittance* of Bark from India. 
Letter from J. E. Howard, Esq., to the Under Secretary of State for India, 
June 15th, 1864. 
Sir,—I have the honour to report that I received, on the 20th May, 
the specimens mentioned by Mr. M'Ivor in his dispatch of the 17th 
March last, and that the same were all in good condition. 
I have since devoted most careful attention to ascertain by experi- 
ment the probable market value, especially of the first two samples of 
bark sent. It will not be necessary for meto detail the various means 
by which I succeeded in convincing myself, not only of the existence of 
the alkaloids, but of their being extant in such a state of purity as is 
certainly not found in the ordinary samples of red bark imported from 
South America. The result of my examination tended to show dis- 
tinctly, that cultivation has improved the produce of at least this 
Species of Chinchona.t ' 
` # The first remittance was received in the spring of 1863, and the second in Oc- 
tober, 1863. : à 
+ The same does not seem to hold good of the C. Calisaya in Java.
