  1'lhc A9ta7, con-ing out of thlle Hleart, A'as divided into three TrUncks.
'T'he
le ift IVdw the Aorta deJceWds whiclh made th Croire, l by turnin- towards
the
riglht fidc as in the Geiwrality of B3irds. The two other greatcr lTrunclks
were
tCic ;ii!lrcs, \v-hich hauing caft torth two fimall Branches, which wvere
the
tarotijes, w ere divided into f veral other great Branches, whichi were alnoflt
all c ployied and difributcd into the Muicles of the Wings. rhe Carotides
a Iittlu above their Origine, had each a Gland1, which was ilflned to them.
Thefe Glan,1ds wVerc two lines long, and a fintw thlick.
  In the lower Beak on both fides of the Tongue, under tle inward Tunicle
of the M0outh, there was found two Glandulous Bodies, from whence pro-
cccded flveral Lympbeducls which opened into the Mouth, and there ditlhlar-
ged, beinfr Iqueczed,a white and Vifcous humour. There were tvsro of theill
towards the upper part a great deal bigger than. the others. 'T'he Tongue
was
fleffi_ at top, and Cartilaginous underneath as in Hcds.
  TtI'e Tfnicle of the Palalte was rough, with a great number of little Nip-
pies, and of hard and Membranous points. It likewvife included a glandul-
lous Body, which 0hot forth two great Du5as's opening into the Mouth.
IT'here was difcovered a great quantity of other little glands at the fides
of the
Larynx, which had alfo obme Lymphedticls.
  The Cranium or Skull was above half a Line thick. The Brain was divi-
ded in two, as generally in Birds. Each part was eleven lines long, and fe-
ven broad. The Certellum was eight lines every way. Both together weiglhl-
cd but a Drachme and a half,                                    b
  The internal Eye-lid was large, and was eafily extended over the whole
Globe of the Eye.
  The Punt#an Lachrymale was double, round, and very large. It opened
as is ufual into the cleft of the hinder part of the Palate. The lower Glan-
dula Lachrymalis was coucht under the Globe of the Eye in the great Canthb.
It was ten.lines long and two broad. Its Dmuifts was great, and opened be-
tween the Eye and internal Eye-Lid. Having Syringed into this Dudits, the
Gland fwelled very much. The upper Glandula Lachrynali6 was very lmiall
not exceeding three Lines in length and two in breadth.
  The Sclerotica was Cartilaginous before, having as it were a harder Ring
than the relil, three lines broad. The Cornea had a border or vellow Circle
quite round, joyning the Conjunaiva. The Iris was of a dark red: the Ta-
petum of the fame colour; the reft of the Choroides was extraordinary black,
We found not that other black Membrane like a Sack, which proceeds from
the Optick Nerve, and which we have always found in the Birds that we have
diffeaed, without being able to conje&ure what its ufe may be. All that
we could furmife is, that this part has an Office like to that of the CIoroides,
in that the one and the other do, amongfc other things, ferve to prepare
the
Nouriffiment of the Humours of the Eye; which, by reafon of the tranipa-
rent purity that is requifite for them, muft have an Aliment very pure, and
wholly exempt from the grofs and Earthy parts, by which Bodies are ren-
dred Opake: for thefe parts, which may be called the Lees of the Blood,
are feparated therefronm  and retained in the Ch/xoides and Purfe of the
Optick
Nerve, which are fullied and blacked therewith; this being done almofi af-
ter the fame manner as the Choroides, Placenta, and Membrane of the Vterw
