270 ANIMAL REPRODUCTIONS: 
Both the pomatia and nemoralis he found inept 
for reproduction, but it was otherwife with a va- 
riety of the latter. On the 19 of July 1768, 
one was decapitated, and part of the neck, along 
with the anterior portion of the foot, likewife cut 
off. It was long before reproduction commen: 
ced. The foot, however, was repaired on the 
16 of September ; but the head did not appear 
before {pring 1769: and in fummer, the whole 
was complete, except the mouth, lips, and fmall- 
er horns. ; 
In another fnail, decollated 14 September 
1768, the upper lip was already formed, March 
1769, and the opening of the mouth had become 
vifible. A third, decapitated 14 September, had 
repaired moft part of the head during the follow- 
ing fummer. : 
Muller terminates his memoir with obferving, 
that a fubfequent journey had prevented further 
examination of the reproducing heads; but that 
the reftitution of feparated parts had been indif- 
putably proved. 
The Padré Scarella of Brefcia repeated my ex-

cated the refult in the following letter: ‘ After
