which was that I put in water, for he came out 
of his (hell, and carried it on his back about the 
bafin. The reft, I fuppofe, died by being kept too 
long in water ; for, on the firft difcovery, I let 
them remain in the water until the Monday fol- 
lowing, when I poured off the water, the fnails 
being ftill out of their (hells, and feemingly dead. 
They lay in that ftate until Tuefday night, when 
I found they had all withdrawn into their (hells ; 
and, though I feveral times fince put them into 
water, they (hewed no (igns of life. Dr. Quin 
and Dr. Rutty did me the favour, at different 
times, to examine the fnail that is living; and 
were greatly pleafed to fee him come out of his fo- 
litary habitation in which he has been confined up- 
wards of fifteen years, for fo long I can with truth 
declare he has been in my pofleflion ; as my father 
died in January 1758, in whofe collection of 
foffils thofe fnails were, and for what I know 
they might have been many years in his poftef- 
(ion before they came into my hands. The (hells 
are fmall, and of one kind; white, ftriped with 
brown. Since this difcovery, I have kept 
this fnail in a fmall phial, with a cover with 
holes, to let in air; and he feems at prefent 
very ftrong, and in health. I (hall be extremely 
glad, if this plain account I have given you would 
induce gentlemen to make fome further experi- 
ments on this fubjeCt. I am, Sir, 
Your mod obedient, 
humble fervant,
