g of both species. If further
evidence was wanted, the skulls will fully prove the distinction of
species; for the skulls of two adult animals compared will show a
difference in size alone which must preclude all supposition of their
being one species. Mr. Owen's remarks are, however, so conclusive,
that I need not dwell on this point; and with a suite of skulls,
male and female, from the adult to the infant, of the Mias kassar,
which I shall have the pleasure to forward, there can remain, I should
think, little further room for discussion. I may mention, however,
that two young animals I had in my possession alive, one a kassar,
the other a pappan, fully bore out these remarks by their proportionate
size. The pappan, with two molars, showed the callosities distinctly,
and was as tall and far stouter than the kassar with three molars,
while the kassar had no vestige of the callosities. Their mode of
progression likewise was different, as the kassar doubled his fists
and dragged his hind quarters after him, while the pappan supported
himself on the open hands sideways placed on the ground, and moved one
leg before the other in the erect sitting attitude; but this was only
observed in the two young ones, and cannot be considered as certainly
applicable to all.

On the habits of the ourangs, as far as I have been able to observe
them, I may remark, that they are as dull and as slothful as can
well be conceived, and on no occasion when pursuing them did they
move so fast as to preclude my keeping pace with them easily through
a moderately clear forest; and even when obstructions below (such
as wading up to the neck) allowed them to get way some distance,
they were sure to stop and allow us to come up. I never observed the
slightest attempt at defence; and the wood, which sometimes rattled
about our ears, was broken by their weight, and not thrown, as some
persons represent. If pushed to extremity, however, the pappan could
not be otherwise than formidable; and one unfortunate man, who with a
party was trying to catch a large one alive, lost two of his fingers,
beside being severely bitten on the face, while the animal finally
beat off his pursuers and escaped. When they wish to catch an adult,
they cut down a circle of trees round the one on which he is seated,
and then fell that also, and close before he can recover himself,
and endeavor to bind him.
