becaue that thcy could not be touched and rubbed like tie others.  Th'llere
was not likewif& feen any mark or fign of Corrofion in thefu part>
bein nlei-
ther ruffy, roughl, nor uneven.  In one of the Subje~ts the / emtricle was
found filled with a great quantity of Hay. Athenciss fay's that JB;l.irds
do
chew the Cud. In a Parrot, which is a Bird that is obfcrvcd to Chew o-
ver again what it has already fwallowed, we have remarked two Ventricles
feparated one from the other by a long Dilt us or Paffage; which feems to
be made for the ufe of Rumination: But we have found no fuch thinl
in the Buytwrd.
  The Inte/gines meafared four Foot in length, without reckoning the ran
ow
CacUMs, of which the right was a Foot, and the left cleaven Inches; wVhiIlf
is no great lengl for an Animal that eats Hay. The two C'x ums proceeded
as uually from the place where the Colon is joyned to the J.1iam, fLavcii
Inches diflant from the Anas. They tended not from the top down wards,
as Arantius reports le obferved it; but from the bottom upwards, as it is
found in other Birds. The internal Tunicle of the Ilium was folded length-
wife, after the manner of the laft Ventricle of Animals which chew the Cud:
towards the extremity of this Inteftine it had fome crofs wrinkles which
fup-
ply'd the place of the Valve of the Colon.
  About an Inch diftant from the Anus, the InteJ'Zin was contiaded, and
afterwards dilated, making a Pouch capable of containing an Egg. The
two vreters were inferted into this Pouch, Towards its middie there was
difcovered a little hole, which led into a Sack which was as it were a third
Cxaum- which is vulgarly called the Purfe of Fabritius, from the name of
him
who firft defcribed it. This PJrfe or Sack was two Inches long, and three
Lines broad at its beginning, where it was a little firaiter than towards
its
extremitie. Over the hole, whith from the middle of the Pouch penetrat-
ed into the third C'cum, there was a fold of the internal Membrane of the
Pouch, which ferved apparently for a Valve capable of hindering the reflux
towards the top of the Rectum, and of favouring the entrance into the
third Cocks.
  This obfervation of a third Cxcurr, is contrary to what Arifjotle has re-
mark'd in the Inteftines of the Buji-ard, which he reports to have lefs Appen-
dices at their lower extremity, than other Birds ufe to have.
  The Kidneys were three Inches long: They were very deeply cut in three
Lobes, after the manner of Birds. Their Veffels were likewife difpofed as
in other Fowl, except the two Crural Arteries, which are generally double,
and which commonly pafs underneath the Kidneys: For in our Sub-
jeds there was one which paffed over, and another which paffed under, to
go into the Thigh.
   Each TeJlicle was fix Lines long and two broad, being of the fhape of
a
fmall Almond, of a Subftance very firm, and white, The Epididymis, which
was perfeafly black, and of the fame Figure of the Teflidc, contained four
Lines in length and two in breadth. Befides the two Teflicles, in one of
our
Subjeacs there was found a Glandulous Body, which feem'd to be a third. It
was nine Inches long, and fix broad, of an Olive Colour. The Duelus Dc-
