320 MR. J. E. HOWARD ON 
the large proportion of Cinchonidine and Quinidine quite seeming 
to indicate its micranthoid analogies. 
I reserved my judgment of its worth till I received from Mr. 
Morris a sample of the bark of the same plant grown in Jamaica. 
I at once saw that it was not the bark of C. Ledgeriana, and 
that, on the contrary, it resembled that of C. micrantha. The 
analysis was as follows :— 
Quinine sulphate ........ 1:06 
Quinmes ce 5... 0:79 
Cimehonidine ....5 12i 0:00 
(nchonme 3,-6.5... 0°64 \ 0:88

showing a slight improvement, which will probably increase with 
age; so that the produce may ultimately turn out better than 
the C. javanica of my plate viii. which gave :—

It is on the whole quite evident that none of these low varieties 
of Calisaya wil repay cultivation, and that no reliance can be 
placed on any descriptions which are unaccompanied by careful 
observations and analysis of the bark of the plants from which 
the seed is taken. 
I was misled by the name Ledgeriana attached to the East- 
Indian seed which I raised; and am now sensible that the micran- 
thoid aspect of the trees noticed by one or two of my Indian 
friends more correctly indicated their true character than the 
erroneous opinion which I had formed by reliance on others. 
l am now able, having received from the Yarrow estate in 
Ceylon seed from trees whose bark yielded from 7 to 12 per cent. 
of quinine, to show living plants of what may safely be considered 
true C. Calisaya, var. Ledgeriana, specimens of which I have the 
pleasure of showing at this Meeting. The rich velvety appear-
