S I R, 
S we have had no further accounts 
of the Quafli Root, fince Dr. 
Linnaeus publifhed the fixth volume of his Amceni - 
fates Academic ce*\n the year 1764, I have, accord- 
ing to your defire, fent you the copy of a letter on the 
good effe&s of this root, which I hope will be ac- 
ceptable to the Society, as it may excite Pbyficians to 
make trials of this medicine which feems to pro- 
mife to be of fo much ufe. The original letter was 
given me by the gentleman to whom it is addrefled, 
while 1 attended him laft year when he was here in 
England for the benefit of his health. 1 am, 
S I R, 
Your moft obedient humble fervant. 
Jermyn-Street, March 8,

D. Monro. 
Dr. Carol. Linnaeus gives a particular defeription and figure 
of the Quafli tree, which grows in the neighbourhood of Surinam, 
in South America, and of the Root having been adminiftred at 
Surinam, with great fuccefs, in malignant, remitting and inter- 
mitting fevers: and he tells us that its virtues were firft difeo- 
vered by a Have of the name of Quafli, from whom the tree got 
its name.
