with a small quantity of salt. As soon as he has shot a monkey, he
follows it through the forest, till, the poison beginning to take
effect, it falls exhausted into his arms. He then immediately puts a
pinch of salt in its mouth, and in a short time the creature revives,
and is led away captive. If old, however, when thus caught, it appears
to be discontented in confinement, and, seldom becoming tame, in a short
time pines away and dies. When a young one is thus caught, it
frequently becomes a playful and interesting pet, and is highly valued
by the Brazilians.

Further to the west, an allied species of this monkey is found, clothed
with red instead of white hair; while, at a still greater distance, a
black-faced and grey-haired species takes the place of the two former.

ALOUATTES, OR HOWLERS.

The voyager up the Amazon, or one of its numerous tributaries, when his
montaria has been moored to the banks, a fire lighted to keep prowling
jaguars or pumas at a respectful distance, his hammock hung up in his
temporary hut, and he is expecting to enjoy a quiet night's rest, is,
ere long, often awoke by the sound of the most fearful howling
proceeding from the recesses of the forest. Now it sounds like the
dreadful roar of the jaguar as it springs on its prey. Now it changes
to the terrible and deep-toned growlings of the wild beast as he is
pressed on all sides by his foes, and now it seems like his last dying
moan beneath a mortal wound. Nothing can be more dismal or dispiriting
than the fearful uproar. Hour after hour it goes on during the night,
increasing as the dawn approaches. Now the howls come from one
direction, now from another, and in far-off parts of the forest. Yet,
terrific as they appear, they are produced by animals not much larger
than a full-grown fox. It is the mycetes, or ursine howler--the largest
monkey of South America.

On advancing into the forest in the morning, three or four may be seen
seated on the upper branches of a tree--shaggy-haired animals, with long
prehensile tails like those of the spider-monkeys--hideous-looking
creatures, with pyramidical heads, the upper jaw descending much below
the cranium, while the branches of the lower one ascend very high, for
the purpose of containing a bony, drum-shaped expansion of the larynx,
which gives to its voice that prodigious volume of sound which makes
night hideous.

They differ somewhat in colour. Some are entirely black, ot
