the animals of the refurgent property for ever, or 
if there was any reafon to hope that it might be 
recovered. In a being like the wheel animal, this 
hope did not feem chimerical, nor would it have 
been wonderful to fee it recover the faculty which 
it naturally poflefles. I have preferved fand that 
had been expofed to heat, and from time to. time 
wet it with pure water, and. often obferved it. 
The fame has been done with fand expofed to 
liquids and odours, keeping it in the air and 
weting it with frefh water, that the noxious qua- 
lities which injured the wheel. animals might be 
deftroyed. But the numerous dead bodies have 
never been re-animated by thefe methods. 
The wheel animals, which fuggefted the opi- 
nion I have laid down, were for the greater part 
found in fewers and the hollows of tiles, among 
a fubftance which, for brevity, has been. called 
fand, though, to {peak more properly, it is a mix- 
ture of earth, fand, and the fragments of tiles. 
This fand, for I fhall continue to call it fo, 
is the abode of wheel animals, but in fome 
kinds they are much more numerous than in 
others. It is fingular, that if the fand is reddifh, 
it is almoft a certain indication, according to 
Baker, of their prefence. They are always in- 
animate when the fand is dry. By ‘one- accuf- 
tomed to obferve wheel animals in the dry ftate 
fram evaporation, of the water, they are eafily 
recognized
