A View of tie ouljide of the forepart of the womb, as it appear-
J i ed when quite cby; exhibiting a fpecimen of the uterine vejels, at
the part where the -plzccnt^i adhered. ..
The veins were filled with yellow wax, and are readily difimguijhed
by the largenefs, light'colour, and frequent anallomofes,/rem ifc
teries, which are here fmaller, kfs numerous, ferpentine. and oj a darker
• colour. The arteries were all convoluted; but they did not appear to be
fo numerous, becaufe many of the branches were filed with the yellow
•wax, which had been thrown into the veins. This isfeen, tn one inflance,
at the letter A. ' ', , j • ,
The deeperfeated veins could not be difinllly feen through the dried
. fubflance <^Jhe womb, and are therefore reprefenled with the Jame obfcurily
and 'confufion which appeared in the objeSl itjelf.

The infide^ of the placenta,' íw/hc/í was injeâed by the umbilical nef
[els after it ivas taken out of the womb.
• A Abrafs-pipe tied into one of the umbilical arteries, by which the two
arteries xuire filed with green wax.
• B A pipe in the vein, by which it was filed with blue wax.
C C The amnion left loofe upon one part of the placenta.
D D The internal fuiface of the placenta, xuhere the amnion was "moved
covered by a continuation of the chorion: upon this are feen the fir t
branches of the umbilical veffels. ' The arteries are fiifjiciently diftinginjliable
by their lighter colour.
They appeared fo from being filled with a lighter coloured green wax,
and from the tranfparency of their coats: biifon the navel-flring it was
the contrary; becaufe the vein, being the mofi central, was covered with
a greater thicknefs of the gelatinous fubflanceof the firing, and therefore
did not allow the darker-coloured Mue wax to befo xoeRfeen.
E Part of the decidua left at'the edge, and turned over the infide of the
placenta, > as to fimo ils outer fuiface (whieh had adhered to the immbj
full offmali vejfels, iufeaed xvith yellow wax from the uterine veins.
The body of the placenta was uniformly filkd xmth theyellow wax.
Thü had fo compleatly filled all the cellular fubflance of the placenta
that upon the infide it appeared every where through the chorion. And
the wax xuas every where mamfefily granulated; fo thai Ü had plainly
filled natural cavities : for if it had filled the fubfiance of the placenta by
common extravafation, it would have formed itfelf into irregular and large
maffes. From this injeñion of the Jpungy or cellular part, the placenta
had acquired at leafi double its natural thicknefs.

Aportion of the internal furface of the womb, from 1 who died
two days after delivery. , ,rn.j
When thefe ten plates were finifhed, I intended to have publijhed
them immediately; and this third figure was added, as the only fupplement
which I could give at thai lime. Itfiews the difference between
the furface of the immb (A, B, C,) where the membranes had adhered, and
that furface (D, E, F,) to which the placenta had been fixed. Thefirfi
was much morefmooth and uniform; the latter was full of large venous orifices.
At the firfi examination, all thefe orifices were found filled up with
plugs of coagulated blood, which profeSledfome way into the cavity of the
womb. The pari beingfieepedfome time in water, they became whiter
and many of them fell out, or xuere pulled out, to fliew the orifices of
the veins more clearly. In this fate the drawitig was rhade.
