are thefe. Alihough I ufed more force, with equal 
^care, to feparate the AlUntois from the Amnios in this 
place than in any other i^where neverthelefs the reparati-

not take it to be the eiFeft of Chance, or my Separati6n.

had the Amnios been ftill joyned to the AlUntois (as thefe 
Objeftcrs fuppof.^ ) the AlUntois hdow this Line muft 
have appeared ihicker than that part above it, fince the 
Amnios alone much thicker than the AlUntois. Tis 
eafie indeed to conceive the Amnios running an entire 
Bladder^
