The Gamecocks and the Partridge

A MAN had two Gamecocks in his poultry-yard.  One day by chance
he found a tame Partridge for sale.  He purchased it and brought
it home to be reared with his Gamecocks.  When the Partridge was
put into the poultry-yard, they struck at it and followed it
about, so that the Partridge became grievously troubled and
supposed that he was thus evilly treated because he was a
stranger.  Not long afterwards he saw the Cocks fighting together
and not separating before one had well beaten the other.  He then
said to himself, "I shall no longer distress¹ myself at being
struck at by these Gamecocks, when I see that they cannot even
refrain from quarreling with each other."
