180 EXPERIMENTS 



E X P E Pv. xxxviir. 



I tlien inlpcded the tefticles of the young, 

 cow, which had never brought forth. They 

 were rather Uirger than thofe of the other cow ; 

 but, what is not lefs remarkable than true, there 

 was not a fingle cicatrice on either of them. A 

 number of lymphatic veficles appeared on one 

 of the tefticles; but there was no veftige of glan- 

 dulous bodies. Upon the other tefticle, I could 

 difcern the rudiments of two glandulous bodies, 

 one juft beginning to fpring up, the other as 

 large as a fmall pea. There were alfo many 

 veficles, which appeared, after being pierced 

 with a lancet, to contain nothing. The glan- 

 dulous bodies, when openad, gave forth nothing 

 but blood.

1 cut each tefticle of both cows into four parts, 

 and, having put them into feparate vials, I pou- 

 red as much water upon them as was juft fufH- 

 cient to cover them; and, after corking the vials 

 clofe, I allowed them to infufe for fix days. I 

 then examined the infufions with the micro- 

 fcope, and faw an amazing number of moving 

 globules, [pi. VI. fig. 23.]. In all the infufions, 

 the globules were extremely fmall, but very 



adive.
