During a stormy night the cattle all mingle together; but the next morning the tropillas separate as before; so that each animal must know its fellow out of ten thousand others.
On two occasions I met with in this province some oxen of a very curious breed, called nata or niata.

They appear externally to hold nearly the same relation to other cattle, which bull or pug dogs do to other dogs.

Their forehead is very short and broad, with the nasal end turned up, and the upper lip much drawn back; their lower jaws project beyond the upper, and have a corresponding upward curve; hence their teeth are always exposed.

Their nostrils are seated high up and are very open; their eyes project outwards.

When walking they carry their heads low, on a short neck; and their hinder legs are rather longer compared with the front legs than is usual.
