thofe of the Cinchojia officinalis as depidted in a plate fent 
out by Mr. banks. 
The bark of this tree in general is fmooth and grey 
on the outfide, though in feme rough and fcabrous. 
When well dried, the infide is of a dark-brown colour. 
Its flavour at firit is fweet, with a mixture of the tafte of 
horfe-radifh and of aromatics of the Eaft; but, when 
fwallowed, of that very bitternefs and aftringency which 
charadterifes the Peruvian bark. It yields thefe qualities 
ftrongly to water both when cold and in decodtion. Half 
an ounce, boiled from two pounds to one pound of water, 
made as ftrong a decodtion as three times its weight of the 
Cinchona vera. The colour was brown, but not turbid. 
I have had many opportunities of trying its effedts, 
efpecially in remittents, which are the moft common 
and fatal fevers in thefe climes. A vomit or gentle 
purge, if neceflary, was firft given; and then imme- 
diately this bark fo foon as they operated. I obferved 
that it ftrengthened the ftomach, checked retching and 
vomiting, corredted morbid humours in priina via, and 
conquered fpeedily the difeafe. My fuccefs in fuch a 
dangerous malady leaves not a doubt on my mind, but 
that it will prove equally efficacious in every other cafe 
where a tonic and antifeptic medicine is indicated.
