When I €5{nmin'd farther into the Alecs Leaf, I difco- 
verd another ibrtof VelTels or Canals, in which the Sap 
appeared fonit: what Pvcddifh. 
itook the Sap out of the feid Veffels, to try whether 
there were any Salt Particles therein, and what Figure 
they were oL 
I let this Sap ftand a little that fome part of it might 
evaporate, and the Salts coagulate, and placing fome of it' 
before my Microfcope, 1 obferv'd with wonder a great 
number of long, flender Particles, that lay in the Sap, 
and were (harp or pointed at both ends \ and forafmuch- 
as I imagined that thefe long Particles could not be co- 
agulated in that fmall time that the Sap was preft out of 
the Canals, but rather that they were there before, I 
cndeavour'd to bring the faid long Particles out of the 
Veflels, fo that there fhould come very little Sap with 
em, that the Painter might fee them more diftindtly 5 
which having brought to pafs, I caufed a few (out of fe- 
veral hundreds that in a (hort time I had heapt together) 
to bedefcribed, as you nSay fee in Fig. i. EFGH. 
The faid flender Particles appeared thro the Microf- 
cope very clear and tranfparent j I laid them upon a 
clean Glafs plate, and viewing them about three weeks 
after, I faw with wonder that fome of them hadafTumed 
a Peach color, and efpecially fuch as lay clofe, or upon 
one another. 
My next Attempt was to know how thefe fharp Parti- 
cles were ranged or placed in the VefTels, and whether * 
they were to be found in all Canals. 
At laft, after feveral Obfervations, by Breaking and 
Cutting in pieces the Aloes Leaves, I brought my trat- 
teri fo far to beafc^ that I placed them fo nicely before 
the Paintevi Eye, th^t he could not only fee the torefaid 
long pointed Patfides lying in thofe Rings or Circles, 
which I imagin'd to ferve for Canals, as in Fig. 3. 1 K L 
in the middle of five rows between I and K 5 but I caufed
