well from thofe that lay upon it, as from thofe that lay 
wnder it* 
Now if we confider that thefe Membranes can't be co- 
ngulated by the Air, fince they are not made by every 
Evaporation or Exhalation of the raoifture, but that fuch 
Membranes mufl be composed (without doubt) of an infi- 
nite number of Fibres, fo fmall that they efcapc our fight, 
we have frefh caufe to ftand amazed, and to fay with our 
felvcs, what unconceiveable Wonders are fhut up in fuch 
a Leaf. 
I thought it not amifs to reprefent a fmall Particle of 
what I caird the Rind or Dark of the Leaf, as it was cut 
through acrofs, and dry'd up irregularly. 
Fig, 7. A. by RPABCSaB.fliows afmall part of the 
Leaf, as it w^as cut off at Fig. 8. between D H 3 and which 
parr, withSQ^RPA, lay inwards, as is defcribed in Fig. 
8. by H 3 and in the fame Fig. 7. A. lay on the outfide of 
the Leaf, as is (hewn by B C. 
Now thefe parts which in Fig. 7. A are cut acrofs be- 
tween A B and C S, are the very (ame parts which in 
Fig. 3. IK LM are reprefemed lengthwife, with this dif- 
ference only, that Fig. 7. A. is drawn from a lefs Mi- 
crofcope. 
One would judge that moft of the afore- mention'd 
Parts are compofed of roundifli Membranes, that include 
a Sap, which Sap v^as mingled with exceeding fmall green 
Particles, and thofe Particles are fo united to each other 
in right lines, that there is no fpace between them, ex- 
cepting that which appears to be Canals. 
I told you above, that I had fqueez'd the Sap out of 
the Aloes Leaf, in order to difcover what Salt-pai tides 
would coagulate in the fame. 
I placed therefore the faid Sap upon ray Scrutore feve- 
ral times, 3ifP||ilways obferved that when the Water was 
raoftly evaporated, there remain'd abundance of Salt 
particles behind, which were almoft all of 'em Quadran- 
gotar
