Mr. Arrof could only find two different forts of the 
Tree, and he believes that the other two forts of the 
Bark are owing to the different Climates where it 
grows, and not to a different Species of the Tree. The 
Bark called color ada and amarylla , is the bell, and 
differs from the b lane a in this, that the Trunk of the 
former is not nigh fo big as that of the latter, the 
Leaves as deferibed above 5 whereas thofe of the 
blanca are larger, and of a lighter green Colour, and 
its Bark has a very thick fpungy Subftance, whitifh on 
the Outfide, and is fo tough, that it requires the Force 
of an Ax to (lice it from the Tree : Tis true, indeed, 
it is as bitter when cut down as the belt Sort, and has 
then the fame Effedl in intermitting Fevers; but when 
dry and long kept, turns quite initpid and good for 
nothing : And it is to beobferved, that both Sorts have 
a much furer and quicker Effecl in Cures when green, 
than when dry. As the bad Sort is in great Plenty, 
and the belt very fcarce and hard to be come at, large 
Quantities of it are cut yearly, and fent with a little of 
the fine Bark to ‘Panama for Europe. 
The Tree of the crefpilta is the fame with that of 
the amarylla and color ada, but grows in a cold 
frofty Climate; by which means the Bark is not only ' 
alter'd in its Quality, but is alTo whitifh on the Outfide, 
though cinamon- colour'd within, and ought in Me- 
dicines to be rejefted. This Sort and the blanca grow 
plentifully in the Province of Ayavaca, fo Leagues 
fiomPiura, and d2 from Payta , a Port in the South- 
Sea ; as alfo in Cariamango , Gonfonama and Xim- 
huro, whence they commonly fend it to Payta , and 
there fell it as the beft. The blanca likewife grows 
in the Province of Quenca, and in the Mountains of 
Caxamarea :
