i63 EXPERIMENTS 



either in the epidydimis or feminal veffels, a 

 quantity of feme n fufficient for obfervation. In 

 the fmall drops 1 could collect, 1 found nothing 

 but globules without motion. As thefe experi- 

 ments were made in March, I imagined that, by 

 repeating them in October, which is the time of 

 rutting, I m/ight find more licjuor in the vefTels. 

 i cut fcveral tefticles in two longitudinally, and 

 having coileded a fmall drop of liquor, 1 flill 

 could perceive nothing but motionlei's globules 

 of different fizes.

I took three tefticles of three diilerent rams, 

 cut them into four parts, and put each of them 

 into a glafs-veflel, with as much water as was 

 fufhcient to cover them, and then fhut the veffels 

 fo clofe as to exclude the air. 1 allowed the 

 tefticles to infufe during four days ; after which 

 I examined the liquor in each glafs with the mi- 

 crolcope, and found the v/hole full of moving 

 bodies ; mofl of which were oval, and fome of 

 them globular. They were equally large, and 

 greatly refembled thofe defcribed in Exper. Vill. 

 Their motion was not rapid, but equal, uniform, 

 and in all dlredlions. In each liquor, the mo- 

 ving bodies were nearly of the fame fize ; but, 

 in the one they were larger, in the other lefs, and, 

 in the third, ilill more minute : They had no 



tails ;
