 a brifk motion, like that of the tail of a ferpent 

 when its head is fixed. In the femen of young 

 animals, when examined before they have any 

 fexual appetite, he alledges that he faw the fame 

 minute animals, and that they had no motion : 

 But, when the feafon of love arrived, the ani- 

 malcules moved with great vivacity. 



In the femen of a male frog, he faw animal- 

 cules ; but, at firft, they were imperfed, and 

 had no motion : Some time after, he found 

 them alive. They were fo minute, he obferves, 

 that ten thoufand of them were only equal in 

 bulk to a fmgle egg of the female. 



In the femen of a man and that of a dog, he 

 pretended to fee two fpecies of animalcules, re- 

 fembling males and females. Having fiiut up 

 the femen of the- dog in a fmall vial, he fays, 

 that a great number of animalcules died the firil 

 day ; that, on the fecond and third day, flill 

 more of them died ; and that few of them were 

 alive on the fourth day. But, having repeated 

 this experiment on the femen of the fame dog,^ 

 he found, at the end of (even days,' the animal- 

 cules as brifk and lively as if they had been 

 newly extracted from the animal : And, having 

 opened a bitch that, fome time before the expe* 

 riment, had been three times covered by the fame 

 dog, he could not perceive, with his naked eye, 

 any male femen in the uterus or its aippendages ; 



but.
