I have been thinking with my felf whether each of the 
aforefaid Oval Particles were not provided with a Valve, 
which Valves make them appear like fo many Oval Fi- 
gures 3 and the life of which Valves might be to hinder 
the Juices or Saps, which by the force of the Sun are raifed 
up into thofe partsjalling do wn or defcending,after the Sun 
fet 5 efpecially if we confider, that by the faid Canals there 
muft becaufed fo ftrong a Protrufion. in Spring time, as 
not only to thruft away and feparate the Bark from the 
Wood, but alfoto burft theoutermoft parts of the Bark, 
that are already hard, dry and withered. 
I have faid before, that the Horizontal Veilels or Ca- 
nals in Cinnamon are Hexangular, which Figure is the 
moft perfect, and takes up the leaft room or fpace 5 
from whence I conclude likewife that the Horizontal 
Vefiels in Fig- 11. are likewife Hexangular, tho I did not 
fee them lying in the fame order 5 for when I examin'd 
into the Horizontal Veffels or Canals of the Cinnamon, [ 
found that they were of the fame Configuration as in 
Fig. II. NS and PQ, viz. that they confifted of Oval 
Figures* 
I had placed before a Microfcope a little bit of a Lime- 
Tree, which was cut off of the Wood lengthways, and 
the Horizontal Vefiels cut acrofs, to the end that you 
may fee how thofe Horizontal Vellels or^ Canals lye in 
the Wood 5 the which Vefiels are alfo continued into the 
Bark, fo far as it is alive, and ferve for the feeding and 
increafingofthe farae> 
Fig. 1 2- ABCDEFG reprefents a little flice of the 
Lime- Tree Wood, in which you may count in 9 feveral 
places the Horizontal Vefiels or Canals that are cut acrgfs, 
and which Canals are fituated between the fmall afcend- : 
ing Vefiels, which for the moft part donourilh the Wood. ^ 
Mow between the Horizontal Veffels and Canals in the 
Wood and in the Bark there is no difference, but in the i 
Afcending Veflfelsand the Bark there is a difference; for
