Thirdly > The Diftin&ion of Animals into Vivipmus and O- 
viparcus is confidered $ and ic is (hewn, that if the Word Vi- 
viparous fignifies according to the Etymology of it, fuch as 
bring forth live Young, then Animals of the fame Genus may 
be (ome Viviparous and fome Oviparous : So for Example, 
Some Serpents, as the Adder, are Viviparous, and fome, as 
the common Snake, Oviparous : But if the Word Viviparous 
fignifiesfuch Animals as continually afford Nourifhment to the 
Foetus during gefta don from the Womb .it (elf: And Oviparous 
fuch as either lay Eggs, or produce perfect Eggs, that is (uch 
as contain all the Nourifhment of the Fxtus till ic be excluded, 
though they retain fuch Eggs in the Womb till exclulion, af- 
fording them only warmth and harbour ; then the diftin&i- 
on may be of good ufe ; and as well (uch Serpents and Li- 
zards as hatch their Eggs in their own Bodies, as thofe that 
lay them in a Dunghil, or other warm place to be cherifh- 
ed and hatch'd by the Heat of the Sun, may be called Ovi- 
parous, 
For the more eafie and clear Comprehcnfi<7n and Diftin&i- 
on of the feveral Kinds of Animals, Mr. Ray gives two Schemes 
or Tables of them : The firft a General one of all Animals ^ 
the feconda Particular one of Quadrupeds.
