the common trunk of the carotid and fub-clavian arteries. The 
large intercoftal nerves being exactly under the fame circum- 
stances on each fide, it was impoflible there could be any tranf- 
poiltion in them. It appears then, from the foregoing descrip- 
tion, that every thing admitting of fuch a change was com- 
pletely tran fpofed in the thorax.

The liver was fituated in the left hypochondriac region, the 
fmall lobe being towards the right, and the great lobe in the 
left-fule. The ligaments uniting it to the diaphragm cor- 
refponded to this change, the right tranfverfe ligament being 
longer, and the left being fhorter, than ufual. The fufpen- 
fory ligament could undergo little change, except being pufhed 
to the left-fide along with the liver. On prefling upwards the 
liver, fo as to exhibit its poflerior and under furface, the gall 
bladder was feen on the left-f.de preferving its proper relative 
fituation to the great lobe of the liver, and the velfels of the 
portae were found upon difle&ion to be tranfpofed correfpond- 
ing to the change of circumftances. The hepatic artery was 
found climbing up obliquely from the right towards the left, 
before the lobuius fpigelii, and entered at the ports into the 
fubftance of the liver by two or three branches on the right of 
the other veffels. The ductus communis cholidochus was on 
the left of the other veflels, being formed from the ductus 
hepaticus and ductus cyfticus in the common way, and it palled 
obliquely downwards on the lefr, to terminate in the duode- 
num. What was mod remarkable, of which indeed I never faw 
or heard of any inftance before, it terminated in the fore- part of 
the duodenum. The vena portarum palled behind the hepatic
