t we here trench on the subjects of sympathy and
fidelity to which I shall recur. Some of Brehm's monkeys took much
delight in teasing a certain old dog whom they disliked, as well as
other animals, in various ingenious ways.

Most of the more complex emotions are common to the higher animals and
ourselves. Every one has seen how jealous a dog is of his master's
affections if lavished on any other creature; and I have observed the
same fact with monkeys. This shows that animals not only love, but have
a desire to be loved. Animals manifestly feel emulation. They love
approbation or praise; and a dog carrying a basket for his master
exhibits in a high degree self-complacency or pride. There can, I think,
be no doubt that a dog feels shame, as distinct from fear, and something
very like modesty when begging too often for food. A great dog scorns
the snarling of a little dog, and this may be called magnanimity.
Several observers have stated that monkeys certainly dislike being
laughed at; and they sometimes invent imaginary offenses. In the
Zoological Gardens I saw a baboon who always got into a furious rage
when his keeper took out a letter or book and read it aloud to him; and
his rage was so violent that, as I witnessed on one occasion, he bit his
own leg till the blood flowed. Dogs show what may be fairly called a
sense of humour as distinct from mere play; if a bit of stick or other
such object be thrown to one, he will often carry it away for a short
distance; and then squatting down with it on the ground close before
him, will wait until his master comes quite close to take it away. The
dog will then seize it and rush away in triumph, repeating the same
maneuver, and evidently enjoying the practical joke.

We will now turn to the more intellectual emotions and faculties, which
are very important, as forming the basis for the development of the
higher mental powers. Animals manifestly enjoy excitement, and suffer
from ennui, as may be seen with dogs, and, according to Rengger, with
monkeys. All animals feel _Wonder_ and many exhibit _Curiosity_. They
sometimes suffer from this latter quality, as when the hunter plays
antics and thus attracts them; I have witnessed this with deer, and so
it is with the wary chamois, and with some kinds of wild ducks. Brehm
gives a curious account of the instinctive dread, which his monkeys
exhibited, for snakes; but their curiosity was so great that they could
not desist from occasio
