part of the plant which is to be the body and root of the 
tree, that which was defigned for the pith, and even the 
wood itfelf may be difcover’d. 
Fig. 456. fhews the root when the plant vegetates, 
T V and W X the two halves of the kernel, and Y that 
part which is to become the body of the tree. 
Fig. 457. reprefents the young plant of twelve days 
growth, whereof A C D fhews the root, and F G that 
part which is to be the tree, D E the feed or kernel, 
which being furrounded with its membrane, which was 
taken off the better to expcfe thofe parts to view, that ferve 
for the nourifhment not only of the root, but of the upper 
parts of the plant likewife, as alfo the fhort firing D. 
Thus we may fee how frnall a particle, that is no bigger 
than a grain of fand, c as the plapt was at firft, is in- 
creafed in biilk ! and all this is brought about by heat 
and moiflure, it being rais’d to this degree of perfection 
in feme fand firft moiffened, and then inclofed together 
with the feed, in a glafs tube, wore all day in the pocket, 
clofe to the body, and at night, placed within a large tin 
bottle, filled with hot water, which is a plain demonftra- 
tion that the plant, and all that belonged to it, was actu¬ 
ally in the feed; that is to fay, not only the young plant, 
its body, root, and fruit, but even its feed alfo, to perpe¬ 
tuate the fpecies; as hath been before obferved. 
Mr. Leeuwenhoek comparing the animalcula in femme 
mafculino, and thefe plants, computes them to be one 
million times fmaller than a plant in an orange-kernel ; 
and though we cannot make our obfervations of the 
growth and increafe of the faid animalcula from time to 
time in their mother’s matrix; yet we may certainly 
conclude, that the laws which the wife creator of all 
things hath preferibed to himlelf, in the production both
