II. SEMINAL VERMICULt; ^8^ 



hended I might be deceived, and that any differ- 

 ence of fize might arife from portions of femen 

 attached to them ; but I was now convinced it 

 could not be the cafe ; becaufe when the feminal 

 fluid was completely diflblved, they retained the 

 fame fize, though tranfmitted through another 

 fluid. Fig. 2. pi. 2. Motion ceafed two hours 

 after taking the femen from the body. 



The feminal fluid of a man was like milk ready 

 to coagulate, March 8 (i). A fmall portion 

 taken for examination, prefented a fmgular phe- 

 nomenon. Four corpufcules were attached, by 

 the filaments, to a diffolving clot. They feemed 

 to make every effort to difengage themfelves from 

 this incumbrance, by many motions and contor- 

 fions ; afcending, defcending, now turning to ei- 

 ther fide, now remaining motionlefs ; the fila- 

 ment fometimes deicribing a curve, and fome- 

 times extending in a flraight line. Amidfi; the 

 ftruggles one difengaged itfelf, and began to 

 fwim like the reft, with an ofcillatory and pro- 

 greffive motion. The other three corpufcula, one 

 after another, did the fame, and the clot gradual- 

 ly diffolved. 



The novelty of the phenomenon made me de- 

 firous to examine whether other ovular corpuf- 

 cula could be found in fimilar fituations in 



molepules
