       ________ of Six~              L PORCUPINES.
viz. the one flefhie and rcd, as in the true Kidney; the other glandulous
whitiflh; therm two Subliances were mixeLd together, fo that this Kidney
being cut, did flewas it were feveral rays which went from the Circuinfc-
rence to the Center, almoli after the fame manner as it is fcen in the Cerebel-
4m of Man. At the Center of this Kidney there was a Cavity capable of
containing aimidling Bean. The Jvafg LErmlgentia made an acute Angle with
the Truncks of the (>ava and UAorA, lavingtheir Origines much hligiler
the Kidneys, which feemed drawn downwards.
  .The Bladder was very large and thick; being comypofd of two Cooats,
which included between them afubftance fpongious and fornewhat flethie.
In one of the Sub~eds, as it has been already declared, all the back part
of it
adhered to the ilnteioir par-t ofthe Epiploonson which it was laid. the fare-
part, which. touched the Persincxjm, was lefs fleihie. It was loofe rin this
place without being joynned to the Peritonxim.
  The TeJticlek of the Males were long 4nd narrow, containing only four
lines in breadth and an inch and half jn length. The Vafa Pr&eparantia
faftied to the inferiour part of the Tef'riclc, and did form an lpidiyrnis
rated from the Tefficle. This Epi didrnis was fafined to a Ligament, which.
pafling into the. 'l7ltighs, did f&em to be mnadg to itrengthlen the
Teticle, and
perform the Office attributed to the round Ligament of the -tertu.
  The .ParaJ~et mwero extraordinary great.: they were two inches and a half
long, and feparated into thref branches; and in fome of our Subjefts into
like branches od 4oral. At the end of the w  there was a bone of an inch
lkng.         ..-                              ,..-
  In the Females the broad Liment of the Matrix was hirongly fafened
to: the Kidnys, at .the baftard-ibs.  The Teflicles were of a Gland ulous
Subfance, without any appearance of Bladders or Eggs.
  The Nervous Center of the Diaphragmc was fo thin and transparent, that
the Lungs were feen through. There were five principal Lobes, which
were each divided into two. The Rings of the AJpera Arteria were not in-
tire. The Trunck of the Arter'a 'Venofa and its chief branches were of an
extraordinary length. Having tied the Azygos in one of our Subjeds, and
put a fmnall pipe underneath the Ligature, when it was blown, the Vena C-
va fwelled, beginning to fwell through the Iliaca, by reafon of the Commu-
nication of one branch of the Azygos, which palling beyond the Ciaphragrne
went to make an Anajtomofis with one of the the branches of the I/jack.
  The Heart was two inches in length from the Bafts to the point, and four-
teen lines in breadth through its middle between the point and the Bafts,
ing fomewhat larger in this place than at the Bafts: it was blunt at the
and the flefh of the left Ventricle wv as firm and hard. It had an Eminence
which made it to appear winding like a Screw. The right Auricle teemed to
be only a dilatation of the Cava. In one of the Subjedts the two Auricles
the Heart were filled with a flimy, white, and very folid Subfrance, and
Ventricles with a black and congealed blood.
   The Brain was almoft like that of the Hov. There was no bone between
 the Cerebrum and Cerebellum
   The Globe of the Elye exceeded not four inches Diameter: it was almoft
 Splxrical. The Cornea was elevated like ademi-globe on another Globe
