ture influenced the refurre€tion of animals, the 
arm-polypus would certainly be one; and it feems 
fo much the better adapted for refurreétion, as it 
continues-ative notwithftanding every method has 
been taken:to deftroy animation. It is demonftrat- 
ed, that thefe polypi fuftain no injury by being 
turned feveral times outfide in, like a glove, or by 
being cut afunder.. If the head is cut off, a fort 
of hydra with many heads arifes, each of which 
receives food by a different mouth. If thefe new 
heads are cut off, new hydras. fpring up; and 
each head creates a polypus fit for the formation. 
of more hydras. In fhort, every particle, even the 
{malleft fragment of a polypus, unfolds and be- 
comes a new polypus.. If an animal fo mangled. 
and lacerated does not die, will it not be very 
credible that, only being allowed to remain dry, 
it may ftill retain the faculty of refurre€tion ? But 
fasts prove the reverfe. The arm-polypus al- 
ways dies when the water evaporates ; and this- 
happens equally whether it is immediately expof- 
ed to the air, or lies concealed among its native 
fub-aquatic herbs. When the water is almoft. 
exhaufted, the arms are retracted into the ani- 
mal; it contracts within itfelf, and dies. It never 
recovers, though water is copioufly fupplied. I 
{peak of the arm-polypus, for it is the only fpecies. 
I have been able to find, and is the fimalleft of 
Trembley’ s arm-polypi.
