toe ANIMALS KILLED IV, 
hermaphrodite without fex: it multiplies both 
by divifion and fhoots. The puceron of plants 
is lefs an hermaphrodite ; it has a fexual diftinc- 
tion; and although it propagates without copula- 
tion during fummer, at the end of autumn it is 
obferved to copulate. Earth worms, fhell fnails, 
naked {nails and many {pecies of fhell fith are lefs 
hermaphrodites: each is at the fame time male 
and female, but infufficient alone for generation. 
They give and receive ; they fertilize and are fe« 
cundated. 
The difcovery of refurgent animals is far from 
being as extenfive as that of reproduction or her- 
maphrodifm ; but this arifes lefs from the fear- 
city of fuch beings than the rarenefs of the phi 
lofophers who have entered on this branch of na- 
tural philofophy. Leeuwenhoeck was the firft 
who, by his reviving wheel animal, drew the 
curtain from before thefe obje&ts: and feems 
furprifed at a fa&t which was unique and unexam- 
pled in nature: and, indeed, no one thought 
there was another creature in all the animated 
world poflefled of this prodigy. But fince the 
profound refearch of more modern naturalifts 
has difcovered others, I doubt not that the num- 
ber of thefe wonderful beings will increafe as: 
the ftudy is cultivated. 
The fame gradations perceptible in hermaphro- 
dites and in reproducing animals cannot be expec- 
ted in the refufcitant. There may be a greater or
