tvc draws it in : B ff the Inferior par# it adheres to tbfc Pe- 
ritontnm, which is faftned tothe lower Shell f fo that by 
all thefe Ligaments the Pericardium is kept diftended fuf- 
ficiently, that the Heart hath an entire liberty in it. 
In this Pericardium there is found a good quantity of 
a very clear and iranfparent Water, which hath the 
fame ufe there, as that which- is found in the Pericar- 
dium of cither Animals.- 
Tis in the middle of this Pericardium that the Heart 
is fufpended } to wit, at its Bafs by the Arteries, and at 
its Inferior part by a little Tendon, or a very thin Li- 
gament, which from the Point or Cone of the Heart, 
afcendeth to iiifert it felf to that part of the Pericar- 
dium which adheres fo the Back. 
This little Ligament is very remarkable in this, that 
by its means the Point of the Heart is fufpended on the 
Level of its Bafts 5 without which ’tis vifible that the 
Point of the Heart would Tall lower, and bend the Vef- 
c fel^*>f which might have interrupted the free 
Circulation of the Blood, and by confequence would 
have endanger’d the Life of the Animal. 
e : The Pericardium being opened, the Heart appeareth 
if it was (landing by itfelf, being only fix’d to 
the Arteries which go out of it (fuppofing the Animal 
turned upon its Back) its Auricles being feparated and 
hid under ks Bafts and Arteries, towards the Back of 
the Animal j which is very different fiom the Sea Tor- 
toifes, where the Auricles are fituated on the Right and 
"Left Ar%ie of its Bafis, by which way they pufh the 
Blood into the Heart. 
The Figure of the Heart of this Animal is almoft 
lenticular 5 making neverthelefs three obtufe Angles, two 
on the Bafts, one to the Right, and the other to the 
Left } the third is at the Inferior part, where the little 
Tendon, which fufpendeth the Heart on the Level of its 
Bafs , is inferred.
