whether the Trees which we find without Seeds may be 
therefore called Male Trees. 
I think it now paft all doubt, that the Generation of 
Animals is from an Animalcule in the Male Sperm: And 
tho I have often fancied that I have difcovered the Parts 
and Membranes of the P<etus in this Animalcule, fo as 
to fay there is the Head, there the Shoulders, -and there 
the Thighs, yet I will affirm nothing herein, till I fhaH 
be fo lucky as to find an Animalcule large enough to di£ 
cover this Truth, which I am not quite in defpair of, fmce 
I have been fo fortunate as to meet with in the (mall Seeds 
of the Aft), Leaves and Rudiments of the future Plane 
far larger than in the Seed of any Plant I have yet ex- 
amined. 
But to examine the matter a little clofer : Nature pro- 
ceeds almoft after the fame Method in her Operations as 
to the Production of Plants and Animals : For as the 
Animalcule of the Male Sperm cannot live in the Ma- 
trix, without being wrapt up in the feveral Coverings, 
and receiving its Nourifnment ; fo neither can the Seed 
of the Plant iubfift without continual nourishment, and 
-has alfo its Coats to encompafs it: And which is obfer- 
vable, as the Fat us has but one ligament confiding of 
feveral Veflels, by which it is faftned and nourifh'd, fo 
all the Seeds which I have feen have but one Ligament, 
made up of feveral Veflels alfo, which is fometirnes lon- 
ger, fornetimes ihorter. I will prefent the Reader with 
the Draughts of fome Seeds. Fig. §. A B C is the out- 
ward Membrane of the Seed of an Ajh, A D the place 
where the Seed it felf lies, which is taken out and re- 
prefented by E F. A F is the Ligament by winch the 
Seed E F receives its Nourifhment, the part A being on- 
ly joy ned to the Tree ; and what is more obfervable, the 
point of the Seed F where the Ligament is faftned, is 
likewife the place whence the Root proceeds : So that 
the Root is the la-ft that parts from the Tree, which at
