I have view'd thofe winding Particles that lye in the 
Canals or Veffels of o.ther Leaves, when they were fo ex- 
ceed ing fmalland fine, that it was as much as one could 
do, with a ftiarp Eye and a good Glafs, to perceive their 
Meanders, or Serpentine Motion* 
After this I took that particle of the Aloes-leaf which 
I had before examin d kngthwife , and cut it acrofs, 
and view'd it in that pofition, that I might difcover the. 
Orifices or Openings of thofe Canals that in Fig. 4. are 
defcribed in their whole length by A BC D. 
In Fig* 5. HIKL are reprefented ( as they appear d 
thro a Microfcope that did not enlarge the objeft fa 
much as that thro which I view'd Fig- i. and 2.) fix great 
Tubes, which fhow themfelves in the laft mentioned Vef- 
fel or Canal, in which alio there are a gjeat many other 
lefler Pipes. 
V Thofe fmailer Pipes or Veffels,, which are to be feeii 
about H, have other crofs Canals that Gome out of 'em, 
from whence proceed the inwardly [og great Mem- 
branes, with the Sap that is in tliem«

cutacrofs,and in Fig, 7. A. is alfoftiown by P CLR, how out 
of the Canals fo divided the Meiiibranes proceed, in which 
moft of the Saps are includeda, and of which Membranes 
the greateft part of the AlQes4e^ 5 and thofe 
Mernbranes, with the Saps that lye in em, are fo clear and 
transparent, that you can f%e nothing but their Circles 
or.Gircuniferences^ as in R C^ „ . f - 
Between thefe Membranes there are Canals,; but very 
few, with their Bra nches, that run the length of the 
Leaf, from whence alfo' the Membranes proceed 5 and

.with Membranes, and the Matter fhut ug {11 jjjjie^m,,. and
