T His Learned Author^a worthy Member of the i?. Society jin difcour- 
fing upon this no lefs difficult than important fubjeftjObfcrves this 
Method; 
Firfi^ he lays for a ground,that there is and needs muft be Motion in the 
Bloud, iSfrW^, he declares; what kind of Motion, and how various thac 
is,(hcwing aIfo,that all thbfe motions are to be adfcribed to the Vital 
Bloud.^ndtobc prefcrved therein. T/?/W-!)',hemaketh it his bufinefsto 
prove ( which is his main dcfign) that thofe Motions are both continually 
produced,and maintained by the means of i?f/5'^V4^'*(?»,premifjng fomething 
about the Nature and Properties of the ^i^-jand the Fahricl^ and Motion 
of the PneHmatick^ parts. 
This done, he (hewcth the probability of his Hjfpothep,^s being intelli- 
gible,and able to folvc innumerable queftions, and among them fuch , as 
have been efteemed almoft infoluble. And^r/?,he teaches,how Refpira- 
rion maintains that Trogreffive Motion, which he alfo cals the Motion of 
Rivers and then,how it preferreth the Motions of F/mdit j^^nd prarmth^ 
by the Airs fubduing,comminuting,and dilating thjC Blood. Where he 
digrefleth to give an Anfwer to thofe,that will not allow the Air to have 
?iny ingrefs into the Bloud; as alfo to explain the caafe of Sanguification^ 
adfcribing it neither to the Heart nor the Liver , but principally to 
the Lmgs in thpfe thit are borne ; but in FaM's^to the maternal Bloud, 
and the Vmbilical veffels. 
iV^m,heproceeds to explicate the many Prohkms of Refpiration by 
the delivered Hjpothefis: And chiefly why Refpiration is fo abfolute- 
ly ncceffary to Life,viz.becaufe Life principally confifts in the motion of 
the Bloud;which foon ceafeth, when Refpiration is ftopp*d. Upon which 
Queftion thus refolved,depends alfo the folution of divers others, to be 
found in this Book. 
To all which he adds the reafon of the Difference, there isj asto RefpIratioHj between 
the Borne and Vn-borne I folvingthat knmty Hervean Problem » vix* Why a Ftetus, 
being divefted of the S'econdine , and having once breathed in the open Airjcannot liye 
afterwards without it , but dyes prefently ? Which he imputes to the hindred Motion of 
the Bloud > entertained by Refpiration. 
But why, after that Refpiration hath once begun , the Bloud will not , when th*re is 
Rcedjreturn to its former paflage through the formtn OvAlt $ we refer to the Author 
liimfclf for an Anfwer: as we alfo do for other «onfidcrablc^plutiofls of m8Dy other 
difficulties occurring inthis Learned Treatilc»
