diflocate the limbs, I did not fail to make this 
experiment. But it is much more difficult to 
diflocate a limb than to amputate it; for the 
pliancy and lubricity of the members contributes 
to render the experimentalift’s exertions abor- 
tive. 
On the 13 of July, I performed this new ope- 
ration on two large newts, at half paft two, 
It is of fome confequence to attend to the 
exaét hour. Both arms of the one and both 
thighs of the other were diflocated. The opera- 
tion was indubitably complete ; for, befides the 
fenfation felt in performing it, which convinced 
me of the fact, the members immediately after. 
wards were pendent, as if dead, and the animal 
had no longer any power over them, which was- 
an unequivocal proof. 
At fix in the morning, on the 4, it was im- 
poflible to recognife any fymptom of diflocation, 
In the evening, each newt moved the disjointed 
limbs with a liberty and facility which announ-

This and the preceding experiment are cruel in- 
deed ; and fenfible minds will hardly pardon the 
gbferver’s cruelty, though it arifes from an evi-
