141. Spallanzani showed that in several European aquatic salamanders 
the eggs are internally fertilized; and as there was no direct contact of the 
cloace in the sexes he supposed the zoosperms became diffuse in the 
water and ultimately found their way into the cloaca and oviducts of the 
female.
