from the heat of Animals: So that the greenefs which happens to Copper
in the Ventricle ofthe Ofirich, cannot proceed fi-orn a Diffolvent, that
it has
to Digeft Metals; but there is a probability, that the Diffolution is there
made, after the fame manner as if it mould have been done out of this Ven
tricle, if the Copper had been champed with Herbes, or forne acid or faline
Liquor, of what Nature fiever it were, and which fhould be very different
from this acid or falt ; or elfe from that general Diffolvent ( whatever
it be, )
of all that is capable of affording Nouriflnient: So that it is credible
that
the (JI rich being a Voracious Animal, which has need of Swallowing forne
hard thing, that is requisite, as has been faid, to break its Nouriffiment;
it
rnifufes the inflin& which Nature has given it for that end, when it
Swal-
lows Iron, and efpecially Copper, which is turned into Poifbn in its Sto-
mach, inlicad of turning into Nourifhment. And indeed, we were inforllb-
cd by thof& who look after thefe Animals in the Aviary of Verfilles,
that
the Oflriches which do Swallow much Iron, or Copper, do all Dye prelcntly
after.
  The Inteflines in our Subjeds were different in length, altho' the Animals
were almolt of the fame fize. III one they were fifty Foot, in another fOuL--
ty two, in a third thirty three, in a fourth twenty nine. The tIree finaller
Intef/ines, had fcarce more length than the Colon and RedtoH together. The
Cxectm was doubled, as in molt other Birds: each comprehending two Foot
in length, more or lefs, in proportion to the length of the other Intejlines.
  The External Surface of the Colon and CGcm were uneven, with fome ve-
ry regular Boffes, but different in each of thefe Intcjlines. Thefe Boffes
were formed by fome leaf-like Ligaments, which were on the infide, al-
moft the fame as they are feen in the third and fourth Ventricle of Animals
which chew the Cud. In the Colon thefe leaves were tranfverfely fituated,
each making more than half a Circle, and being alternately placed; 1o that
the ends of two Semicircles, did receive and include the extremity of ano-
ther Semi-circle, as if one did put the Teeth oftwo Combes within one an-
other. Thefe Semi-circles were half an Inch diftant from each other, and
wvere but three Lines broad in their middle, and went lelfing to nothing-
All along this I*teJline, in the Pofteriour Part, there was a Ligament two
Lines broad, which being in length a third lcfs than the lJitejt'ine, did
con-
traft it, and make the Interiour and Semi-circular Ligaments to Form thd
Folds and 13Bofes, which appeared flill more observable, when the Intefline
being blow n up, the whole Membrane, which was not retained and held
by the Ligaments, was extended by the impulfion of the Air. All the
Veffels entered at the fide of this Ligament, to diltribute themjelves into
the InteJtine, butparticularlyinto the Leaves. This Struature of Leaves
tranfverfely feated in the Colon hath already been obferved in rhe Ape,
where mention is made of the discovery that we have nTade, of fuch Leaves
in the ?Jejanum of Man; but we deferred to give the Figure thereof till we
came to the (ricbh.
   TI he Cecum was likewife furniflied with Leaves on the infide, or rather
with one tingle Leaf, which turned like a Screw from one end to the other,
almoft after the manner described in the Sea-Fox, and as it is in Hares,
and
Rabits.  l his Leaf was of the fame breadth, viz, five Lines every where
                                                                      It
