8 SEMINAL VERMICULI- tly 
From: all this, and from all that has already been 
faid, we muft conclude that the animalcula of 
infufions, confequently thofe of putrid femen, 
are of a nature and conftitution effentially diffe- 
rent from feminal vermiculi. That it is truly fo 
we may eafily determine, fince a fluid which af- 
fords a falutary dwelling to the one is fatal to the’ 
other. Putredinous feminal animalcula origi- 
nate and livein corrupted femen, but die in that 
which is recent and entire. On the other hand, 
vermiculi live with fafety in recent, but perifh when. 
put in corrupted, femen. The animalcula be- 
come more lively and active when water is mix- 
ed with the femen; the vermiculi, at leaft feveral — 
fpecies, become motionlefs and die. Of the 
whole of thefe facts I have often convinced my- 
felf: Whence, I conclude infufion animalcula 
and {permatic vermiculi to be two different fpecies 
of animals which we cannot confound: without 
outraging nature.
