The defign-, then, of this paper, is to lay before 
this Society fome further reafons, why theie plants 
cannot be the fame ; and that even if they were the 
fame, Mr. Miller has produced no authority to fhew, 
that this juice was ever made ufe of for this purpofe 
abroad ; with fome remarks on his reply to my let- 
ter, in which he obliges me to be more particular 
than I intended, in explaining fome errors, which I 
find he has run into. 
In my letter to Mr. Webb, I have pointed out the 
exa<£t defcription, which Koempfer has given us of 
the leaves of this plant, fhewing how much they 
differ from our American one : but now I fhall 
mention fome obfervations that efcaped me before, 
and which, I think, will give us a clearer proof of 
this matter. 
Koempfer, then, informs us, that this Japan var- 
nifli-tree, or Sitz-dJju , is a tree, not a fhrub : and 
this author (it is well known) is remarkably exadt 
in the defcription of his Japan plants, making the 
neceffary diftin&ions between a fhrub, an arborefcent 
fhrub, and a tree. He then goes on to explain the 
manner of its growth ; and tells us, that it grows with 
long fappy fhoots, very luxuriantly, to the height of 
a fallow or willow-tree, which we may reafonably 
allow to be from 20 to 30 feet : whereas this Caro- 
lina pennated Toxicodendron, as Mr. Miller tells us 
in his Dictionary, 6th edit, in folio, is a fhrub, and 
feldom rifes above five feet high with us : and many 
people, who have been in North America, agree, 
that it is but a flow grower there, and is one of the 
fhrubby underwoods of that country : fo that, al- 
lowing it to grow even double the height it does 
. here.
