perfect Animals, as they are commonly called, fuch 
as Worms, where, on the Separation of the Body into 
two Parts, Life has continued feemingly in both, and 
with ftrong Signs of ir, longer than we have had the 
Patience to attend and examine. We have been, in- 
deed, quite uncertain, in which of the Parts this feem- 
ing Life has been mod confpicuous : and as both Parts 
have feemed to endeavour to get away, and have 
frequently foon after been found milling. Boys and 
ordinary People are generally polfelTed of an Opinion, 
that they unite and grow together again after their • 
Separation. 
Now, if it could once be allowed, that Animal 
Life and Senfationmight fubfiftbut anlnftant, in both 
Parts of the Creature, after its Sedion ; the whole 
remaining Difficulty would be only as to the Cure of 
the Wounds, and the Reprodudion of the necelfary 
Organs that are wanting. And, for the firft of thefe, 
we know very well, that the more imperfed Ani- 
mals are killed with much greater Difficulty than the 
more perfed, their Vitals being more diffufed, and 
their general Organization being, I fuppofe, far more 
Bmple than that of the higher Tribes: And as to the 
other, I think no one will fee any Impoffibility in 
the Reprodudion of certain Parts, after what we have 
feen and read of, in the Lobfter and Cray-fi[h Kinds, 
who when they chance by any Misfortune to lofe a 
Claw, reproduce it in a ffiort time, with all its Joints, 
and the proper Mufcles for moving them * all which 
appears as difficult as the regaining of a Mouth and a 
Tail to fome of the Worm-kind > whofe general Or- 
ganization being fimple, and confiding chiefly of only 
one ftrait Gut, or Pallage, from the Mouth to the 
Venr,
