ik. SEMINAL VERMICULL 7 
admitting they pafs from water to animated bo~ 
dies, they may poflibly undergo fome change or 
alteration, operated perhaps by the caufes the 
Genevefe philofopher details, which has been ren- 
dered probable by demonftrating, that animals 
which change their climate and aliment fuffer 
fuch mutations, ‘ Rane in Ebufum Infulam de- 
¢ late colores mutant; Oves in regione fepten- 
‘ trionali albefcunt, in meridionali nigrefcunt. 
Sic Vulpes, Urfi, Lepores mutato loco, colores 
¢ et quandoque mores mutant.’ I likewife ac- 
knowledge that the body of vermiculi may 
change its proportions; that the parts may be- 
come larger or {maller according as the new ele- 
ment agrees with their nature; as alfo happens 
in plants carried to a foreign foil; but I cannot 
-_ acy will lofe their priftine figure to af- 
fume 
oaly one, (which he calls Cercaria), refembling the feminal 
vermiculi of the ram. But this fpecies, which is the only 
one that has been obferved, and is very feldom found, (in 
infufione animali raro), would be far from being able to 
give exiftence to all the different {pecies of vermiculii—A. 
Muller makes this remark on the Cercaria Gyrinus, 
There are others of the fame genus that may refemble 
feminal vermiculi; and perhaps fome of the Trichodz. 
But of the many hundred figures in his Animalcula Infi- 
feria, 2 work that no animalculiff can want, certainly 
there are none that may be confounded with the vermicu- 
fi: Many, however, have tails unconnected with the mo- 
tions of the body.---T,
