IV. Reproduction of newts.—It is long before 
I arrive at that part of the hiftory which is moft 
interefting, namely, the reproduction of the mem- 
bers of newts. My experiments began 5 June 
1777; and, in the courfe of that and the follow- 
ing month, fifteen newts were mutilated, fome 
very young, and the reft full grown. All the 
former died, and feveral whofe increment was 
complete. As this treatife is limited to the 
fuccefsful experiments, thofe that were fruitlefs 
thall be fuppreffed. 
I fhall denominate the anterior extremities, 
arms and hands ; and the pofterior, ¢egs and feet : 
circuitous expreflions will thus be avoided. 
On the hand are only four fingers, but there are 
five toes on the feet. It has already been remark- 
ed that they are well articulated, and nearly refem- 
ble our own. ‘They neither have nails, nor are 
they connected by intermediate membranes ; but 
I repeat, that my purpofe is to avoid defcriptions.
