302 CORRESPONDENCE OF RAY. 



channelled. Thus defining a compound leaf, I seclude 

 several sorts of compound or pinnate-leaved plants from 

 being PhyU'dides or Hemionitides, &c. 



The objection concerning the cocoa-nut you have very 

 well cleared and answered. But your balsam tree can- 

 not be Dr. Plukenet's, unless he be grossly mistaken in 

 applying a wrong fruit to it, which yet I cannot wonder 

 he should, since I find him often tripping. 



Concerning the tree called cedar, in Jamaica, you have 

 informed me, I took it to be no other than a sort of 

 juniper. I once saw a young tree, in a vessel, brought 

 from Barbadoes, which the seamen told me was the 

 cedar, so like our European juniper that I could observe

 writes well in Latin. And finding him to dedicate one 

 of his dissertations to you, I thence learn that he is well 

 known to you and acquainted with you, wherefore I 

 desire some further account of him from you, especially 

 as to his temper of mind. I offered him a sight of my 

 papers concerning the subject I mentioned, which he
