We may pretty ^afily cpiiceive how one Canal is pro. 
diiced (or comes o^^t). from another, but how the faid 
long (harp pointed Particles, reprefented by Fig, 6, 7, 8 and 
9 are produced, is, as well as a great many other Phifto- 
we/i4,^paft my Underftanding. 
I have moreover examined .into the Nature of the Bark 
ot a thick Lime Tree, the rather becaqfe I kno w no other 
Barks oi Trees w.hqfe parts arcio eaGly fejiafared from one 
another, either in length or breadth y infomuch that they 
make thereof in Mufipvji Mats for Packing, and Rope- 
work, which is very ftrong, andiif t am rightly informed, 
is not eafily fubjeft to rot, tho u, jihould Jye lon^ vvet ' 
This Bark I alfo cut .^acroft^j in* order to dj1c6ver the 
Bent or Run of > the Horizor^ral. 'Veffefs that come olit of 
the Wood. ■* 
Fig. lo. ABCDEFGHI reprlfpntsa f^^^ of 
the Bark of a Lime Tree, as it w^s cut acfoft, where, by 
ABC arefliown tbe Horizontal Ye^els that cbrne out of 
the Wood, and confequently thefe Veffels are cut length- 
ways. , ^^'-'^ 
Thefe Veflels, ^ altho at their firft coming out of the 
Wood they lye clofe to one another, as from A to B, and 
from B to C, yet they don't remain always fo clofe, but 
as the Tree grows thicker and bigger, the Horizontal 
Veflels are more divided from one another ^ as for inftancc, 
that which at B is but one Bundle or Colleftion of Veflels, 
with the Increafe of the Tree divides itfelf into two, ^and 
the Separation grows larger and larger, as in B M K and 
BML. 
Now, that there may remain no Interftice or Vacuity 
between the faid Horizontal Veflels, there are other Vef- 
fels produced from tfaofe, as you may fee between M I D, 
which new Veffels produce a Matter that fills the Place of 
MLK. 
Thefe Parts are RoundiCh, but fo interlinkt v/itfa one 
another, that they ferve for Canals 5 they appeared fo 
fmall
