ANIMAL REPRODUCTIONS. 401 
ExperimMENT IV. The limbs of a newt cut 
Jongitudinally through the middle.-—\ divided the 
right hand and foot of a newt longitudinally, 16 
June 1778. Ina few days, the wounds were 
covered with whitifh mould, which grew-rapidly. 
It gradually became thicker and longer, and, 
as I forefaw, announced the lofs of the limbs. 
I .removed it feveral times with a pencil, 
but it conftantly returned. This fingular pro- 
duction requires more profound inveftigation 
than I was able to beftow on it. It evidently 
confifted of extremely delicate filaments, fimilar 
to what charatterife the mould originating on 
humid animal and vegetable fubftances. Some- 
times the filaments grew half an inch long, and 
even more. Something fimilar occurred in the 
frefh water worms, multiplied by fections, in 
1741, 17423; and I then confidered the mould 
as a precurfor of gangrene.’ While obferving it 
on the newts, the fame idea recurred; and I 
thought of anointing the wounds with a pencil 
dipped in a folution of bark, but I cannot affirm 
that this was more efhcacious than the former 
plan reforted to. Whatever was the cafe,-notwith- 
ftanding all my care, the third toe and fecond 
finger fell off about the end of June. Longitu- 
dinal divifions certainly occafion the greateft dif- 
order in the parts, and particularly in the veffels ;
