from them in having neither tail nor cheek pouches. They are
true bipeds on the ground, applying the sole of the foot flatly, not,
as Cuvier and others have remarked of the Ourangs, with the outer
edge of the sole only, but flat down, as Blyth, who first mentions
it, noticed it, with the thumb or big toe widely separated.

I think of all the monkey family this Gibbon makes one of the most
interesting pets. It is mild and most docile, and capable of great
attachment. Even the adult male has been caught, and within the short
space of a month so completely tamed that he would follow and come
to a call. One I had for a time, some years ago, was a most engaging
little creature. Nothing contented him so much as being allowed to
sit by my side with his arm linked through mine, and he would resist
any attempt I made to go away. He was extremely clean in his habits,
which cannot be said of all the monkey tribe. Soon after he came to
me I gave him a piece of blanket to sleep on in his box, but the next
morning I found he had rolled it up and made a sort of pillow for
his head, so a second piece was given him. He was destined for the
Queen's Gardens at Delhi, but unfortunately on his way up he got a
chill, and contracted a disease akin to consumption. During his
illness he was most carefully tended by my brother, who had a little
bed made for him, and the doctor came daily to see the little patient,
who gratefully accepted his attentions; but, to their disappointment,
he died. The only objection to these monkeys as pets is the power
they have of howling, or rather whooping, a piercing and somewhat
hysterical "Whoop-poo! whoop-poo! whoop-poo!" for several minutes,
till fairly exhausted.

They are very fond of swinging by their long arms, and walk something
like a tipsy sailor. A friend, resident on the frontiers of Assam,
tells me that the full-grown adult pines
