the Poplar and Indian Cotton. If thefe diftindlons of 
parts aie fo fbon vifible in thefe foiall Seeds, why ftiould 
we doubt the produdion of an Animal from the fb of- 
ten named Animalcules. Indeed we rnuft own our felves 
at a ftand, when we would find out how theft Animal- 
cules receive Life, and that not before the Male has at- 
tained a certain Age ; and the rather , fince we hold 
that the matter whence thefe Animalcules proceed, was 
likewife in that Animalcule it felf when it was firft com- 
mitted to the Matrix. And indeed that very extraordi- 
nary minutenefs, by which one Creature is tranfmitted 
to another, is incomprehenfible. 
Nor can we be better fatisfied as to this matter in 
Trees than Men for we fee plainly, that very many 
Trees growing from Seed are fome years before they 
bring forth Fruit and Seeds, at leaft fuch Seeds as will 
produce another Plant. So that we cannot fay, that 
that Seed which will produce a Tree depends only on the 
Tree ; but that the fubftance of the Seed, by means 
whereof a Tree is propagated, depends on that Seed 
from Whence the Tree it felf alfb proceeded. And tho' 
w 7 e may after fome manner imagine how the Fruit, zs 
an Apple or Pear, confifling of feveral round Particles 
(to omit the VefTels) may be produced, fince there are 
8 or 10, it may be more Ligaments (each whereof has 
a multitude of Veflels) which may tranfmit feveral 
Juices ye*> how can we conceive that the Origine of a 
Plant can be thus formed. So that we fee the beginning 
of the Propagation of the Tree is to us incomprehenfible, 
although we iee it done before our Eyes ; and we may 
luppole it after the fame way as it is in Man. To con- 
clude, the Tree after 8 or 10 years begins to bear Seed, 
which depends not only on the Tree, but on the former 
Seed : So it is in the Male Sperme> which has its Original 
not only from the Male, but from the Animalcule from
