into the Lungs, whether it may not eaffly, and without 
Inconvenience be difcharged thence, during that 
State of Life the Foetus leads in the Womb: AU 
thefe Doubts I muft confefs my felf unable to deter- 
mine. But however thus much favouring ray Opi^ 
nion, may be obferved in the Sea-Calf, and lucli 
other Animals as have the Foramen Ovale, That the 
Circulation of their Blood is continued, notwith-

As to the Feeping of Chich^ns in the Fgg, about 
which EW/«r bath the fame doubt, as ot ciie Vagitut

more liberty ; or elfe it lies nneafily, or is offended 
with (baking, and therefore Peepeth and Cryeth, as 
when uneafy out of the Shell . i „ -.t. 
And after fome fuch manner I take it to be with 
an Humane Feetus ; that it is sn fome Diforder, and 
uneafy in the Womb, and therefore Cryeth as well
