There was a pretty large paffage into the Arteria Jorta, 
the contrivance of which was very fingukr. For above 
this heart it was made like an Arch of a Circle, into 
which there was a dired paffage from the heart for the 
blood. When I further examin d this Artery I found 
that it went down on each fide on the Vertebrcz of the 
backs between the Kidneys and divided it felf on each 
fide after the ufuall manner after it had lent each Kid» 
ney a branch, the Liver in the right fide one, and the 
Liver in the left fide two. 
The 7th Figure exprefles this, as by the explicatioa 
of it fhail appear. 
Below the former a little towards the left fide of it 
there was another half heart, having only one Auricle 
and one Ventricle like the former. This received little 
blood but what was tranfmitted from the large Liver 
in the left fide by that that is called the Truncus Afcendens 
of the Vena cava. 
The Artery carrying the blood from this heart was in- 
ferted intothe Artery lately defcrib'd as well as that of 
the other -heart. 
So that if the blood circulated through either of them 
the whole Animal muft neceffarily be lupplyed with 
blood; a contrivance not unlike that of the Arterys un- 
der the brain, where the ^r/^^n^ carotides znA Vertebra^ 
les doe empty them(elves into one common channell 
from which all parts of the brain may eafily be fupplyd 
with blood. This is partly expreffed by Fig, 8th but 
not fo clearly as I could wifli. 
How far itisreprefented we fhall fee when we come 
to the explications of the Figures. 
The head was joind to two necks about the -proceffus 
Mamillares. Fig, 9th reprefents the holes through 
which the Medulla Oblongata was continu d into the6'^/- 
nalis. 
There were four orders of ribs, though the body w^as
