“Experiment VI. The tail of a newt ampu~ 
tated tranfverfely—Something important would 
have been wanting, had I negle€ted amputation 
of the tail, which is a very intricate great organic 
fubftance. It is formed of a feries of minute 
vertebra, with arteries, veins, and nerves, and it 
is covered with mufcles and fléfh. 
‘The tail of a large newt is more than two 
imches long, and about half an inch thick, form+ 
ed like an oar, and terminated by a foft point 
Much might be faid of the figure, proportions, 
and pofition of this organ, and with refpect to 
the funétions it has to exercife ; but thefe would 
be details foreign to my purpofe; I only mean 
‘to confirm what Sig. Spallanzani has advanced 
concerning the admirable reproduction of the 
members. 
When the tails of large newts were amputated 
near the origin, I never fucceeded in obtaining 
reproduétion ; the whole died in a certain time; 
and, for feveral weeks preceding death, a kind of 
-whitifh cotton mould grew on the wounds, the 
filaments of which were feveral lines in length. 
Neverthelefs, I cannot think that this affe&ted 
the animal’s life, for I had feen fimilar mould, or 
cottony filaments, on wounds occafioned by ami 
putating the arms and legs. Thefe filaments 
gradually difappeared, and: unequivocal figns of 
reproduction
