them ; for their figure differed from that of thofe 

 in motion, [pi. V. fig. 14.] : They were larger 

 than the moving globules, or the dead ones at 

 the bottom of the liquor, and feemed to have a 

 kind of filTure or opening.

At another time I examined the feminal fluid 

 of the fame dog, and perceived the fame phae- 

 nomena which have been defcribed. I farther 

 obferved, in a drop of this liquor, a mucilaginous 

 part, [pi. V. fig. 15.] from which globules if- 

 fued as in Exper. IX. and thefe globules formed 

 a current, and moved in regular troops. This 

 mucilage appeared to be agitated internally with 

 afwelling or undulating motion, which produced 

 fmall protuberances in different parts ; and thefe 

 protuberances iffued fuddenly in the form of 

 globules, which moved brifkly forward in the fame 

 diredion. Thefe globules differed not from the 

 others, except that they iffued from the mu- 

 cilage without tails. Some of them, I remarked^ 

 changed their figure ; they lengthened them- 

 felves till they referabled fmall cylinders ; after 

 which the extremities of the cylinders fwelledj 

 and divided by the middle into two globules, 

 and both of them moved on in the fame diredion
