ANIMAL REPRODUCTIONS. 363 
yeproduttion afcertained. In a fecond treatife, 
I proceed to relate recent experiments on the re« 
produétions of water newts ; and it will be feen 
that the renowned Reggian naturalift’s difcovery 
here, is no lefs certain than that of the head of 
the {nail. 
It is unneceflary, in this place, to defcribe the 
newts which were the fubjeét of my experiments;

M. de Bomare’s Dictionaire d’ Hiftoire Naturelle, 
which is in the hands of all the world. A newt of

newts are different, being of a yellowifh green 
colour, with light brown fpecks, or nunute lines. 
But I again repeat, that it is not meant to de- 
{cribe the animal, but only to give an idea of 
the wonderful reproductions which I have bee 
held. 
I. Method of preferving newts. —The newts are 
kept in large glafs veffels, full of frefh water, 
which is renewed at leaft twice a week; for it 
becomes turbid in a few days, and it feems inju- 
rious when too long of being changed. Only 
gne is put in each veffel. From time to time,
