I have fevera! times cat the Bark China 'China through 
perpendicularly, or length- ways, in order to difeb- 
ver the Veffels that receive the faid long Particles, and 
by which they are nourifhed 3 but I could never fucceed, 
by reafon of the vaft Number of the long Particles, which 
caufed the fmall Veffels to break in pieces. 
I fteep'd feme of the faid Bark of China China in Ram 
Water, in order to (often it, for the outfide of it is fo 
bard that it could not be cut otherwife 3 however it re- 
mained ftill fo hard, that I could not make ufe of it to 
my Satisfaction 3 but I have neverthelefs obferved fevera! 
times, that the extream part of the Bark had no fuch 
long Particles as are defcribed by Fig. 1. from whence I 
judged, that the faid Parts were dead or perilhed, as is 
ufual in feverai other Barks. 
When I had fepa rated the outmoft part of the Bark from 
the reft, I difcovered, that the Veffels, which moftly com- 
pofe the faid Bark, did net run length-ways, but Hori- 
-zontally in the Bark 3 and whereas in the Barks of many 
Trees I could difeover the Yearly encreafe and growing 
thicknefs, I could never but once difeover the fame in 
the China China ^ at which time I obferved, that the 
Veffels that lie Horizontally therein, (and are no bigger 
than the Hairs of ones Head ,) were fo clofe to one ano- 
ther, that there was not one of thefe long Particles de- 
fcribed by Tig. 1. lying between them. 
Now as the extream part of the China China is almoft 
always rough and very hard, 1 took one of the little 
Barks, whofe outfide was finooth like others, tho' it was 
not of a thicker Wood, and after I had fteeped it about 
14 hours in Brandy, I found it much fofter in the Gut- 
ting, than all the others I had dealt with before 3 by this 
Bark I judged that it had been increafing fix Years in 
thicknefs, before the long Par tides reprefented by Fig.i, 
were made 3 and thus with much lefs labour I could clear- 
ly difeover, that the acceffion or increafe of fix Years 
IS D thicknefs
