right ; and the vena cava fuperior, as well as inferior, were 
feen opening into their auricle on the left-fide of the fpine. 
There was nothing remarkable in the fize or general figure of 
the heart. 
On the outfide of the pericardium the tranfpofition of the 
larger vefiTels was very finking. The longer fub-clavian vein 
was palling from the left-fide obliquely to the right before the 
branches which are fent off from the arch of the aorta. The 
left carotid and fub-clavian arteries were found to arife from 
the arch of the aorta by one common trunk ; the right carotid 
and fub-clavian feparately. 
In the duplicature of the pleura behind, or what may be 
called the poferior mediaftinum, there was a change cor- 
refponding to what we have already defcribed. The defcend- 
ing aorta was found palling on the right fide of the fpine. The 
celophagus was before it, inclining more and more to the right 
towards its lower extremity, and it at length perforated the 
diaphragm fomewhat on the right-fide of the fpine*. The 
thoracic dudt was feen in the middle between the defcending 
aorta and the vena azygos in fome places forming a plexus of 
fmall branches, in another dividing itfelf into two branches, 
which afterw-ards re- united in a common trunk, and at length 
climbing up to terminate in the angle between the jugular and 
fub-clavian veins on the right-fide of the body. The recur- 
rent nerve of the parvagum on the right-fide pafifed round the 
beginning of the defcending aorta, and on the left palled round
