dance of Urine in the Allantoides ; fo that the 

 Fcetus in the Womb doth live, as it were, the 

 Life of a Fifh. Laftly, Why clfe fhould there 

 be fuch an inftant Neceffity of Refpiration fo 

 foon as ever the Fatus is fallen off from the 

 Womb. 



I know that if the Fcetm be taken out of the 

 Womb inclos'd in the Secundines, it will con- 

 tiniji^ to Hve, and the Blood to circulate for a 

 considerable Time, as Dr. Harvey obferves. 

 The Reafon whereof I conceive to be, becaufc 

 the Blood ftill circulates through the Cotyledons^ 

 or Place72ta^ which are now exposed to the open 

 Air, and fo from thence receives fufHcient Sup- 

 plies thereof, to continue its gentle Motion, 

 arKi feed the vital Flame. But when, upon Ex- 

 clulion of the Young, the Umbilical Veffels are 

 broken, and no more Air is receiv'd that Way, 

 the Plaftick Nature, to preferve the Life of 

 the Animal, fpeedily raifes the Lungs, and 

 draws into them Air in great abundance, which 

 caufes a fudden and mighty Accenfion in the 

 Blood* ^ to the Maintenance whereof a far 

 greater Quantity of Air is requifite, than would 

 fervc to feed the mild and languid Flame be- 

 fore. 



This Way we may give a facile and very 

 probable Account of it, to wit, becaufe recei- 

 ving no more Communications of Air from its 

 Dam, or Mother, it muft needs have a fpeedy 

 Supply from without, or elfe extinguifh and 

 die for Want of it j being not able to live longer 



without
