istnd root of thcTixe, Idifcovercd within thefmali Par- 
licle xhsLt which v/as defign'd for the Pith, and even the 
Wood itfelf, and all that as plainly as if I had been obferv" 
ing with my naked Eye a young Plant of an inch thick* 
. 1 endea^our'd as far as I wa^ able, to defcribe the con- 
texture of the Pith, as it appeared to me in Fig. lo. W X 
y in the faid Figure you may obferve a great many 
frnjil Particles,wh1ch at firft fight one would be apt to take 
far irregular Globules, but plac'd in a right line, ^nd all 
of thernof greater length than breadth, but I look upon 
then) to be nothing elfe but fmall Pipes or Vcllels, where- 
by the Plant receives ifs nouriftiment, and who can tell 
but every one of them is cover d with a diftinft Mem- 
brane. 
Thefe faid parts,which compofe the pith of the Plant are 
fiot to be difcover'd, unlefs with a (harp Knife you cut off 
a piece from the Seed after it is ftript of the Seed, and 
place it immediately before the Microfcopc , for all the 
moifture is fo foon exhafd after it is cut, that one (hall not 
be able to make any obfervation. 
Moreover, for my own and others fatisfaflion, I took a 
little Copper-box, and put into it fome Sand, which for its 
whitenefs, and becaufe it is us'd to fcour Tin, we call 
ftouring Sand 5 this Sand was very dry, but was fomething 
moiftn d by the Seeds which I mingl d with it, having 
newly taken them out of an Orange. 
This was done on the 19th of November in the Evening 
about 7 of the Clock, after which I carried the fame Box 
adays in the Waftband of my Breeches, where I us'd to 
put my Watch, and a nights I plac'd it within a large 
Tin Bottle filPd with hot Water, which ray people put in- 
to ray Bed to warm it, by which means the little Box was 
alfo kept warm till the morning 5 and after I had repeat- 
ed this praftice three days following, I open'd the Box, 
and took out one of the Seeds, but could notdifcover any 
change in it.
