CINCHONA BRACHYCARPA. 213 
No opportunity ought to be omitted that can in any way 
make us more acquainted with this valuable genus Cinchona, 
the falutary effects of which give a fecurity and comfort to the 
lives of thofe, in warm and unhealthy climates, beyond any 
other medicine we know of. This fpecies might be ufed as a 
fubftitute to the Peruvian bark; but it is to be regreted, that 
the tree is fcarce and fimall, EN that svadeR of it cannot be 
had, at leaft in thefe parts * 
I po not pretend to hold up this new bark as fuperior, or 
even equal to the Peruvian. I have given it in the flighter 
cafes of intermitting and remitting fevers, with good effect ; 
and in a few inftances, it produced a cure, where the patients 
had taken the common and red bark to no purpofe. 
To people afflicted with intermittents, I gave of the pow- 
der from twelve grains to thirty every hour, or every two hours 
in the abfence of fever. By this means, a {top was put to the 
fever, and the patients recovered. I have alfo adminiftered 
this new bark in dyfpepfia, both in powder and infufion. It 
fat eafy on the ftomach, promoted appetite, and was eafy to 
take. I had fhewn this fpecies of Cinchona to my good friend 
Dr Wraicut, before he left the ifland, and gave him a little of 
the bark. He gave it in powder toa patient, but found it 
emetic, which could only happen from fome peculiarity in the 
_ conftitution +. In his letter to me, he intimates, that proba-~ 
bly the fame thing would happen, with every other of this ge- 
nus, if given before it was completely dried. 
Of 
* This lofs may be compenfated by the abundance of the Cinchona Caribaa feu Ja- 
maicenfis, defcribed by Dr Waicur in the 57th vol. of Phil. Tranf. and which, we are 
affured, has been found to anfwer all the purpofes of the Cinchona Officinalis.
