of the Tolk into the Guts for a fecund coiaion^ thcrfe made by the ?4^. 
creatick Juyce, acknowledged to be excellently handled by the LQavti" 
cdSyhm, and his ingenious Scholar, De Graeffy from the former of 
whom our Autkr yet diffcnts, about the mixture of the Gall with the 
faid juyce in the Heart refuting it by feveral Experiments. 
The //^f/'.explains the Communion of Veffels in Embryo's: Ifrwhom? 
he faith, three AmPomofes are ufualiy obferved, which, as foon as the 
Fietas is born, arc clofed. They are called Foramen Ovak^ Canalis Ar^ 
I teriefm^ and Venofus. The two former to be met with about the Hem*y 
li the laft in the Liwr. All three here defcribed by the Author:, who al- 
fo compares, as Harvey does, the Fcetus yet in the Womb with the 
mannerofoperaiionofthofc Animals, ifcat are provided but with one 
cavity in the Heart^arad with no Lungs 3 the bloud of the Fruh^as long 
as it is unborn, paffing neither through the Parenchyma of the Lungs, 
nor that of the Liver. Laftly, the necelfity of Rtf^iratim is explicated^ 
and how the defe^ of the Lungs, and of one of the Ventricles of the 
Heartgis fupplied in JFi/J^/^W;c.by comminuting and mixing the bloud 
in the GiUs. To which is annexed the manner of Refplration in Am-^ 
fhibia^Sy which ^re furnifht with Lungs and two Ventricles of the 
Heart, and ytt^i{ Bartholin mifinfotmsus not, keep the Ovale 
all their lite time open 5 which yet otir Author calls in qucftion, ailed- 
ging, to have feen no Diving Animals,whichhad not the faid Foramtn 
clofed after their being bornl 
The Sixth makes a digrelfion, to difcourfe of the Biolychniumy and 
thelngrefs of the Air into the Bloud? for the Generation of Spirits^and 
the pretended kindling of avital Flame. But our Author can fee no- 
thing that may prove either the exiftence^ or the necepty of fuch a 
Flame .• On the contrary, he finds the Bloud unfit for taking Fire.and 
judgeth it very difficult to affign either the place or the manner of this 
accenfion 3 which is not made in the Lungs, nor in the Heart, which 
he holds to bcdeftitute of all ferment. To which he adds^frfi, that the 
Heat of the Bloud is not fufficient to caufe fach an inflammation, fee- 
ing how much even good Spirit of Wine muft be heated, before it will 
flame, which it doth not without the aftual application of fire. Nexty 
That Examples are very rare of Liquors kindled by venciiation. Fur-- 
ther^ That Fifhes and Frogs ^ which yet have life, modon, and fenfe, 
are not thought to have this flame, as being aftually cold. Be fides ^ 
That the Animal Spirits are not found in the form of flame 5 which he 
endeavours to prove from ihe WiBf^An doftrine of the manner,in which
