V. A Letter from T)r William Oliver, ^hyjician and 
Fellow of the ^yal Society^ to Mr James Petiver, 
F, 5(. S. concerning the Jefuits Birk. 
^^jyEru Bark^ comes from a Tree about the bignefs of a 
•* Plumh Tree^ with Leaves like Ivy^ but not quite fo big, 
and are always green. The hdtans call it ^eraffgo. 'Tis 
gathered in Autumn^ and the Rind taken off all round, as 
^vellfrom xh^Tmnk^ a^ Boyghs^ which grows again in four 
Months, as Gri^ does : The Trunk, is about the Bignefs of a 
MansThigff: It bears a Frnit not unlike 2iCheJinfit(^txctpt 
its outer Rind or Shell) which is properly call'd ChinaLhina^ 
and is efteem'd by the Natives beyond the Bark taken from 
the Trunk or Boughs, This Account I received from an In- 
genious Apothecary zx. Cadiz, in Spain^ A. D. 1 694. who had 
Jived in Peru^ and feen it growing, and gathered it feverni 
times ; From this Hifiory I made this Ohfervation^ that pro- 
bably China China , or the Rind of the Fruity was firfl: only 
in life, and the more powerful Medicine, ufed in fmaller 
Quantities, and that the Bark of the Tree carpe not into 
play till fome time after 5 when the ^r///e/ of it, known 
m Europey occafioned a greater demand for it, whether 
this be a juft Obfervation or no, I fubmit to your better 
Judgment.
