12 SEMINAL VERMICULI. lL. 
femained long entire; the body and tail were 
complete for a month. In fourteen hours, 
the femen began to exhibit fymptoms of © 
putridity, and then were infufion animalcula 
vifible ; they increafed; and on the fifth day, 
there were many fpecies. One particularly des 
mands our notice: not only did it multiply by 
longitudinal divifion, but the fize and figure’ 
changed every moment. Sometimes the animalcu- 
la contracted and became round ;” fometimes they 
dilated and became elliptical, as 7 have remarked 
“in feveral fpecies of infufion animalcula. 
When this experiment on the femen of the 
horfe was made, one fimilar was made on that of 
the rabbit. The vermiculi perifhed in four hours, 
and fell to the bottom ; animalcula appeared im 
fifteen. Two fpecies multiplied by divifion; and 
one exhibited the contractions and inflations al. 
ready defcribed. 
The fame experiments were made on the fe- 
minal fluid of the ram, dog, and bull; on that 
of frogs and newts, with analogous refults. In 
the beginning, and during the progrefs of putre- 
faction, each produced different animalcula, and 
ail difplayed numerous and different fingularities. 
Their number increafed ; it diminifhed, and be- 
came very fmall. The animalcula were different 
in figure and fize, and fome fpecies multiplied 
by divifion; which proved that animal femen re- 
fenibled
