generated : the opening was complete ; and the 
new lips, very diftinct, were of the figure and pro- 
portions which they ought to be. In a word,

fame f{pecies, which had not been mutilated, that I 
could diftinguifh it only by the tranfparence and 
diminution of fize. It is reprefented fig. ro. as 
drawn from the life: and the plane of the ante- 
rior part, fig. 11. where the new mouth and its 
lips are diftinétly feen. Above. it, the tranfpa- 
rence of the fleth fhews an oblong fpot ¢, which 
is the teeth. of the fnail: the lips can approach 
io it or recede. ‘Thefe.two figures were not de- 
figned till towards the middle of f{ummer. From 
the 23 of June, I began.to fupply the fnail with 
young vine and. lettuce leaves: but it would not 
touch them. After traverfing the leaves and the 
fides of the veflels, it commonly fixed. to the 
covering, and remained. there during complete 
weeks. Notwithftanding its. abftinence more 
than two months. in fummer, it always feemed in 
good health, and is {till in the fame ftate while i 
write this, 21 July. 
I have already obferved, that the eyes appear, 
although the large horns are but beginning to be 
repaired. This was evident in a fnail. decapitat-
