ces in other parts of the body : where he takes notice of a concretion 
fcen by himfelf grown to the Ceneoithc Hearty of nine ounces weight 
in an healthy Body, that died of a violent death s and of the like adhe- 
ring to the S[le(^y Kidneys^ Liver^ without any perceived trouble to 
the Animal yea, of fome found wtihh the heart it felf. 
He adds the Number^ Shafc^ and life of thefe Placenta's s and frfi 
obferves that thofe that are Ktrnd-bearing Animals, or chewing the 
Cud, have many h and . hofe that are C4i:^4^4ri;*^, have for the moft 
part^onc C^k for each Fcettis^^ hvx a woman commonly but ^^^^ though 
{liehappcnxo have many Embryo's. 
He annexes a particular dcfcription of the Platefstd of a Woman, 
as die moft confiderable, and teaches, how it may be moft convenient- 
ly fevered from the Veflcls, to render them confpicuous, which are a 
numerous off- fpring of ArterieSjVeins, and Fibres ; of the laft where- 
of he inquires, whether they be the capillaries of the Arteries^ and 
Veins, or nervous. v^u/;/ ^;'.ni 
The ^i^^f^ of that in a Woman is Orbicular, about a foot large, and 
two inches thick; one of its. Superficies's, convex, but uneven, the 
other concave ^and every where flicking clofe to ihtChcyiff». 
Tl tUj ' of the Placenta's is known to be, to ferve for conveighing 
the aliment to the Fc^ius. The difficulty is only about the manner. 
Here are examined three opinion?, of Curvey^ Everhard^ and Harvey . 
The two former do hold, that the f^r/^^ is nouriftied only from the 
jimnionh'j iht Mouch yet with this difference, that Ci^ri/fjf will have 
it fed by the Mouth when it isperfed, but, whilft it is yet imferfeft, 
by filtration only through the pores of the body,and by a kind'of juxta* 
pofition : hmBverhard^ fuppofing a fimultaneous formatK^n of all 
the inftruments of nutrition together at firft, and efteeming the Mafs 
of bloud by reafon of its afperity and eagernefs unfit for nutrition, and 
ratlier apt to prey upon than feed the parts^ maintains, that the liquor 
is fucked out of the Amnion by the mouth, concofted in the ftomachi 
and thence paffed into the Milky VelTels, even from the beginning. 
Mean time they both a^ree in this, that iht Ewbfyo doth breath,but not 
feed, through the Umbilical veiTels. 
This Gur ^^/W undertakes to difprove ^ and having afferted the 
miUncfsof, atleaft, many parts of the bloud, and confequently their 
fi.cncfs for nutrition, he defends the Harvey an do&vine^ of the Celliqua" 
it or. of the No^rifhing ^t^yct by the Arteries, and its conveyance to. the 
Fvcm by the veins* ^
