remarkable f’rarfpofition of the Vfcera. ^53 
Paper lefs luited to the Society, would not convey more infor- 
mation to perfons thoroughly acquainted with anatomy, and 
would rather tend to obfcure what is more important to thofe 
who have not given lo much attention to fubjecls of this na- 
ture. It may not be improper to obferve, that, befides the 
tranfpofition in the vifcera of this perfon, there are fcveral 
peculiarities which fometimes occur. I have taken notice of 
them in my defcription, although they are entirely indepen- 
dent of the tranfpofition. 
Defcription of the thorax. 
The mediaftinum, or anterior duplicature of the pleura fe- 
parating the two cavities of the cheft from each other, was 
found to incline obliquely downwards to the right fide fully 
as much as it does commonly to the left- fide of the cheft. 
The pericardium too inclined obliquely to the right-fide. On 
preffing it gently away from the lungs the phrenic nerves came 
diftin&ly into view, in their common fituation ; but the right 
phrenic nerve ran more obliquely, and was longer than the 
left. The lung upon the right-fide was divided by a fingle 
oblique fifture into two lobes, having at the fame time a defi- 
ciency oppofite to the apex of the heart ; and the lung on the 
left-fide was divided into three lobes, exactly contrary to what 
is found in ordinary cafes. 
On opening the pericardium the apex of the heart was found 
to point to the right-fide nearly oppofite to the fixth rib, and 
its cavities as well as large veflels were completely tranfpofed. 
What are commonly called the right auricle and ventricle were 
fituated on the left-fide, and the left auricle and ventricle on 
the
