A female rabbit- being killed immediately after the 
coitus, and the uterus opened, innumerable quantities of 
animalcules were found in a frnall drop taken from the 
mouth of the fallopian tube, where it opens into the 
matrix; but none were difcerned in the uterus itfelf, or 
farther along the tube ; they had long tails, and moftly f 
fix tranfparent globules appeared on the body of each, as 
in fig. 171. A; though fome had only one globule at 
the end of the body, and another in the tail, as fig. 
171. B. 
A buck being killed in rutting-time, the vafa deferentia 
Were found turgid, and full of a milky fluid, a drop of

A drop of the feminal matter taken from the teflicles

fo much pleafure in this obfervation, that he called in 
fome neighbours to fhare it with him. 
This ingenious enquirer after nature, opened the 
uterus of an ewe, about feventeen days after fhe had
