Novv for my own and others fatisfadion, I cnt a little 
piece of a Cork as from G, where yr uniay fuppofe that it 
was joyn d to the Tree, ;that is to fay, I cut it after fuch 
a manner, that the cut of the Knife went from G to H s 
and having pkced the faid piece before a Mierofcope, I 
perceived all the Canals fo placed as if they come out of 
the Wood, without difcoveringin the kail any afcending 
Veflels, tho I cut it nsver fo often ^ from whence I mult 
conclude again, that the growth of the Cork proceeded 
from the Wood. 
Now to give you a better Idea hereof, I have caufed 
the Painter to draw a fnull Particle ot the Cork.

a Cork, as it was cut off between G and H, of which 
L M N we muft fuppofe to be the part next the Tree, and 
fo the Veflels or Canals, by which it receives its Increafe, 
run horizontally, as from L to Q., from M to P, and from 
N to O ^ but I could not find one fingle Canal th^t was 
perpendicular, or can be faid to proceed from the Root. 
Tbefe forementibned Canals have no thorough pafiage, 
and it feenis tome that in each Canal there are fo many 
Valves as there are Horizontal VefTelsin (hem- - 
In the faid Figure by a b, isreprefented a Line running 
quite acrofs and fomething incurvated, the which Line is 
that part of the Cork, where, the Seafon of the year being 
overc, a ftop was put to the growth thereofr * ^ 
For further fatisfadion, I cut another piece of a Cork 
after the fame manner that whereas in the foregoing Figure, 
the Horizontal Canals were defcribed in the length, ttow 
the fame Canals were cut acroft.
