Lajtfc Such Sanguineous Creatures as breath by Lungs, and 
have but one Ventricle in their Hearts are enumerated and de- 
(cribed. They are of four kinds, i.Frcgs, 2. Tortoifa, 3. Li* 
zards, /^Serpents: Concerning each of which there are cu- 
rious Anatomical Obfervations added : But efpecially a large 
Befcription ofthe outward and inward parts of the Rattk-fnake^ 
compofed by £he fore-mentioned Learned Perfbn Dr. Ty[on % 
and pubHlhed in thefe Tranfa&ions, Numk 144. the Particu- 
lars whereof I {hall therefore omit. 
Before this Synopfis are premifed (bme Diicourfts concern- 
ing Animals in general. 
As Firft, Whether they are meer Machines, or have any 
Sence and Perception^ that is, whether they refled upon, and 
are confcious of what they door iuffer. The Affirmative 
whereof (eems moil probable to the Author. 
Secondly, Concerning the Generation of Animals there are 
Three Queftions difcufled. 1. Whether there be any Spon- 
taneous or Equivocal Generation ? The Author's Opinion is, 
That there is no fuch thing, but that all Animals, even the 
vileft Infe&s, are generated by Animal Parents of their own 
kind. 2. Whether all Individuals of every. Species of Ani- 
mals, that ever were or {hall be, were at firft created by God, 
or whether there are every day new ones produced by Gene- 
ration? The Author is inclinable to their Opinion that hold 
allwere at firft created, but not confident of it. Seeing nei- 
ther Man nor any other Creature is capable of forming fuch 
an Engine as an Animal Body ; and fince .all Females have in 
them from their firft Formation the Seeds of all the Indivi- 
duals they (hail during their whole Life bring forth, it is 
clear they have no power of producing new ones : and a 
ftrong Preemption, that all that have been or fliall be were at 
firft created. Whether the Seeds of Animals, or rather 
the primordial Animalcules are lodged in the Egg of the Fe- 
male, or in the Sperm of the Male. The Author is of tha 
former Opinion, for many Reafons which may be.ften in 
the Book.
