for further experiments ; but are much more likely to prove successful here than in 

 America, whore thos0 fevers th^t generally pot on the appearance of intermittenis, are 

 attended with nervous syniptoms, and oiLcn mortal ; tiiereiore must require medicines 

 that act more effectualt}- on the whoje habit, and whose active particles can stimulate 

 and provoke the oscillations of the hon'Ous filaments in the more remote parts of the 

 body. These different barks 'yield a large quantity of extraa, which in taste and ap- 

 pearance seems to be the same with that of the Jesuits bark, vvhich has occasioned it to 

 be frequently substituted in the room of that drug-j and tliis, I am persuaded, costs 

 many a life in those colonies, where remittent fevers are so frequent and mortal, it is, 

 however, an excellent astringent, and a very convenient and elegant preparation in 

 that form, which rnay be adminisierec'^ with great ])ropriety and success, whenever as- 

 tringents of a long continued actionaare properly rscjuired. Browne-, p. 202. 



The bark cf these trees has been also found very useful in curing putrid ulcers, by 

 ..giving a strong deccctiort of it inwardly, and fomenting the ulcers therewith.
