Under the diaphragm

on the right-hand side lies the 'liver',
and on the left-hand side the 'spleen', alike in all animals that
are provided with these organs in an ordinary and not preternatural
way; for, be it observed, in some quadrupeds these organs have been
found in a transposed position. These organs are connected with the
stomach by the caul.

To outward view the spleen of man is narrow and long,
resembling the self-same organ in the pig. The liver in the great
majority of animals is not provided with a 'gall-bladder'; but the
latter is present in some.
