fecure from any Confufion, or any preternatural 
Digredions from their due Forms, is moft compa- 
tible with that gracious Dcfign, that all fhould be 
good: For every animal and vegetable Body is daily 
fecn to be conftant to its own Kind, and can be 
'fubjedt to no Accident but one to render it mon< 
ftrous in its Accretion, and that in general is Coni- 
preflion : For all animal and vegetable Ova are 
mod; certainly perfect in their firft Formation, as 
the Seeds of the latter plainly fhew, and in a State 
of Red, until they are depofited in their natural 
Matrix , be it fooncr or later ; the Ova of Females 
in the Ovaria during Life, and the Seeds of Vege- 
tables in our Repofitories for any Number of Years; 
and, after that, would certainly, without Accidents 
or Interruption, continue their perfect Form to their 
utmod: Growth. 
From hence it will be eafy to account for the 
preternatural Adhefton of thefe two Children, and 
the Confufion of their Vifcera , upon the mod; eafy 
Plan, and moft dmple and perfuafivc Reafoning

to account for every other Monftrofity that can at-

We have obferved before, that each Seed and 
Ovum contains the Animal and Vegetable proper 
to its Species. Now, when two or more of thefe 
animal Ova are fecundated, and come into the 
IJtenis , the Sides of the Ova (which are the Mem- 
brances that contain the Fluids in which the little 
Organizations fwim) muft inevitably come into 
Contaft } and if the Membranes of each continue 
in a good State, the Foetus s will be free in their
