1. Cows pasture in herds, and in companies, and if one of them wanders
to a distance, all the rest follow, so that the herdsmen, if they do
not find her, immediately examine all the herds. Mares in herds, if
one of them happens to die, will bring up her foal among them, and the
whole race of horses appears to have warm natural affections, of which
the following is a proof: the barren mares will take away the foals
from their mothers, and treat them with affection, though they soon die
for want of milk.
