The Difpofition of the Arteries which go out of the 
Heart being examined, there remains only the Veins 
which bring the Blood into it from all the Parts of the 
Animal : But firft one muft obferve, that there is no 
Veins which terminate in the Heart 5 for all the Veins 
open themfelves into the Auricles, which are, as hath 
been faid, feparated from the Heart. 
There are two ways to fhow thefe Veins without 
Difledion : The firft is to fill them with Wax, by Syrin- 
ging it into them by their Orifices in the Auricles 5 for if 
one fyringeth by the oblong Orifice in he Auricula dextra y 
all the Yeins of the Body (except thofe of the Lungs) 
will be entirely fill’d j and afterward by Syringing into 
the Oval Orifice in the Auricula, pniftra, the two Veins of 
the Lungs will be full at once thro’ the whole extent of 
Trachea Arteria in the Lungs. 
The other way is toyait till the Animal is expired $ 
becaufe the Heart lofing infenfibly its Vigour, (it beat- 
ing for the fpace of 24 hours,) it has not then the 
force to difeharge itfelf of the Blood which comes from 
all Parts into thefe Veins, which then grow very turgid 
by the coagulated Blood colleded in them : Then you 
need only to turn over the Heart towards the Neck, 
cutting only the little Cororary Vein which comes out 
of the Subfiance of the Heart, for to obferve all the 
great Veins without Difledion ; becaufe they all come 
and end in a common Refervatory, ficuated acrofs in the 
capacity of the Pericardium, joining to the Auricles. And- 
here one may obferve a great Vein, or an Irregular 
Refervatory : In the Tortojfes I have diffeded of 18 
and 20 Inches long, this Refervatory was 10 Inches 
broad, and 18 Inches long. In this Refervatory the two 
Axillary Veins which come from the upper Parts of the 
Body, joyn one another, after having pierced thePerww- 
cUum, one on the Right fide, and the other on the Left. 
From the Inferior Parts there joyn two large Veins, one
