d not meet for months, yet they never
forgot each other, and their friendship continued for several years.

I have had many friends among the lower animals, but have always gained
and retained their good-will through their appetite. Some of these
creatures will be considered queer pets, for instance, grasshoppers,
spiders, and crickets, yet they were very interesting and often showed
much intelligence. The lower animals, with the single exception of the
dog (I do not include the cat, for I doubt her friendship), rarely
accept man as a companion and friend spontaneously. Their appetites or
the exigencies of their surroundings very frequently occasion them to
act in a friendly manner towards man, simply in order to induce him to
befriend them. It is the rarest thing in the world for them to
experience disinterested friendship for him. As I have said elsewhere in
this paper, a few instances of disinterested and spontaneous affection
of animals, other than dogs, for human beings are, however, on record,
and I am happy in being able to record another.

In 1882 there was received at the Fair Grounds in St. Louis, Missouri, a
consignment of South American monkeys. Among the lot were several large
individuals of a species then unknown to me, and which remain unknown to
me to this day. When I entered the monkey house I went at once to the
cage of the newcomers. One of the creatures, after examining me very
carefully, uttered a peculiar cry, and then leaped to the bars and began
jabbering at a great rate. I told the keeper that I believed that the
monkey wished to make friends with me; that the tones of its voice were
decidedly pacific. He laughed at the idea, and declared that this same
animal had bitten him severely when he was removing it from the box in
which it had been shipped to the cage in which it was then confined. I
said nothing more, but, going behind the rail, inserted my hand between
the bars of the cage. The monkey immediately seized it with its paws,
kissed it, and then licked it with its tongue. It then drew its head
down beside it, murmuring all the while in low tones. It showed great
pleasure when I scratched its head and body, and, in fact, seemed to
regard me with the greatest affection. When the keeper, in his
astonishment, drew near, the monkey bounded toward him, chattering and
showing every indication of great anger. This animal never forgot me,
but always recognized me the very moment I entered the mon
