The brains of animals supplied with fat are oily, as in the pig;
of animals supplied with suet, parched and dry. But it is about the
kidneys more than any other viscera that animals are inclined to
take on fat; and the right kidney is always less supplied with fat
than the left kidney, and, be the two kidneys ever so fat, there is
always a space devoid of fat in between the two. Animals supplied with
suet are specially apt to have it about the kidneys, and especially
the sheep; for this animal is apt to die from its kidneys being
entirely enveloped. Fat or suet about the kidney is superinduced by
overfeeding, as is found at Leontini in Sicily; and consequently in
this district they defer driving out sheep to pasture until the day is
well on, with the view of limiting their food by curtailment of the
hours of pasture.
