Ho//W,and how at leaft a whole Clufter of Eggs in a Hen 
are fecundated by one Coition of the Male. 5. This gives a 
new light as it were to the firft Prophecy concerning the 
Mejfiah, that the Seed of the Woman (hall bruife the 
Head of the Serpent, all the reft of Mankind being thus 
moft properly and truly the Seed of the Man. 6. The 
Analogy I have already mentioned, which we may ra- 
tionally fuppofe between the manner of the propaga- 
tion of Plants and Animals, does likewife make this pro- 
bable. Every Herb and Tree bears its Seed after its 
kind, which Seed is nothing elfe but a little Plant of 
the fame kind, which being thrown into the Earth, as 
into its Uttrus^ fpreads forth its Roots and receives its 
nourifbment, but has its form within its felf, and we 
may rationally conjecture fome fuch Analogy in the Pro- 
pagation of Animals. 
The third Particular which later Difcoveries make 
probable, is that Animals cannot be form'd of thefe Ani- 
malcula without the Ova infeminis, which are neceflary 
for fupplying of them with proper Nutriment: And this 
thefe Confiderations feem to evince. 1. It is probable 
that an Animalcle cannot come forward if it do not fall 
into a proper Nidus. This we fee is the CicatricuU in 
Eggs, and tho a Million of them (hould fall into an 
Egg, none of them would come forward, but what were 
in the Center of the CicatricuU^ and perhaps the Nidus 
neceflary for their formation is fo proportioned to their 
bulk, that it can hardly contain more than one Ani- 
malcle $ and this may be the reafon why there are fo few 
Monfters. This we fee is abfolutely neceflary in Oviparfr, 
and the only difference which feems to be between them 
and the Vivipara in this matter is in this, that in the latter 
the Ova are properly nothing more but the CicatricuU 
with its Colltquamentum^ fo that the Fcetus muft fpread 
forth its roots into the Uterus to receive its nourifhment, 
but the Eggs in Oviparis may be properly term'd anVterus 
in
