centa from Women (which is frequently fo great 

 as to coft them their Lives) is as plain a de« 

 monft ration to Rsafbn of the Continuity of the 

 Veffels, as Mr. Cowpers Experimens is to the 

 Eye. ' 



I have heard it obje6red by very Learned 

 Men, that if there were fuch a Continuity of Vef- 

 fels, and fuch Transfufion of Blood, the Fztus 

 muft neceffarily perifh through lots of Blood, 

 upon the feparation of the Placenta from the 

 Vterus ; but that, on the contrary, no vifible 

 Flux of Blood does follow while the Foetus con- 

 tinues wrapt in the Membrane, in which Con- 

 dition it-may be kept alive fbme Hours. To 

 this it may be anfwer d, that the Circulation in 

 the Foetus* being deriv'd from the Mother, may 

 be fappos'd wholly to ceafe upon the cutting 

 off the Communication between them, till it is 

 again renew'd more forcibly by Hefpiration, But 

 if we allow the motion already imprefs'd upon 

 the ; Blood to be fufficient to keep it going a 

 little while j yet it muft needs be fo exceeding 

 languid, that the meer refiftance of the Exter- v 

 nal Air muft be mpre than enough to hinder 

 any Efflux of Blood from a Fcetus before Re- 

 fpiration. How long Life may be prefer v'd 

 without an aSiual Circulation of the Blood, is a 

 Queftion not of this place. But we have been 

 convinced by many and notorious Obfervations 

 and Experiments, that Life has been recover'd 

 a long time after all tokens of Refpirarion, Cir- 

 culation, or even Life it felf, have difappear 1 d ; 

 fo that we can't think the firft Solution either 

 inipoffible or improbable,
