The Hypothcfis of the Antmalciila 
in the Seminal Liquid of Man, appears fupported 
and confirmed by feveral Experiments. Leewenhoek 
has already obferved, that a^ wild Male Rabbet, and a 
tame and white Female, produce young odes intireJy

without a Tail is put among^ ordinary Hens, or . a 
Cock with the Feathers upwards, all the Chicks will

made with Pigeons, with Canary-Birds, A 
Mule fprung from an Afs and a Mare, refembles more 
to the Afs than to the Mare, whereas a Mule coming 
from a Horfe and a She- Afs, has more; of the -Horfe"s 
Nature. All this proves in fome meafure, that the 
Male fiitnifhes the moft effential Part in the Genera-

moft vigorous in the Copulation, they begot Males j 
but if the Seed of the female prevailed, they pro-
