And there is
also a species of hare in what is named the Fig district, near Lake
Bolbe, and elsewhere, which animal might be taken to have two livers
owing to the length of the connecting ducts, similar to the
structure in the lung of birds.
The spleen in all cases, when normally placed, is on the
left-hand side, and the kidneys also lie in the same position in all
creatures that possess them. There have been known instances of
quadrupeds under dissection, where the spleen was on the right hand
and the liver on the left; but all such cases are regarded as
supernatural.
In all animals the wind-pipe extends to the lung, and the
manner how, we shall discuss hereafter; and the oesophagus, in all
that have the organ, extends through the midriff into the stomach.
For, by the way, as has been observed, most fishes have no oesophagus,
but the stomach is united directly with the mouth, so that in some
cases when big fish are pursuing little ones, the stomach tumbles
forward into the mouth.
All the afore-mentioned animals have a stomach, and one
similarly situated, that is to say, situated directly under the
midriff; and they have a gut connected therewith and closing at the
outlet of the residuum and at what is termed the 'rectum'.
