it. A week or two afterwards it was again taken ill, and this time more seriously. The symptoms 
were exactly those of intermittent fever, accompanied by watery swellings on the feet and head. It 
lost all appetite for its food, and after lingering for a week, a most pitiable object, died, after being in 
my possession nearly three months. 1 much regretted the loss of my little pet, which I had at one 
time looked forward to bringing up to years of maturity, and taking home to England. For several 
months it had afforded me daily amusement by its curious ways and the inimitably ludicrous expression 
of its little countenance. Its weight was three pounds nine ounces, its height fourteen inches, and the 
spread of its arms twenty-three inches. I preserved its skin and skeleton, and in doing so found that, 
when it fell from the tree, it must have broken an arm and a leg, which had, however, united so 
rapidly, that I only noticed the hard swellings on the limbs where the irregular junction of the bones 
had taken place.” 
There is evidently much intelligence in the young Orang, when brought in contact with man, 
but probably in its native woods it leads a very quiet and almost mechanical life, there being nothing 
to develop extra instincts, thought, or unusual intelligence. Of course, some are more active than 
others, and many have to use greater exertion than others to obtain food. Hence, whilst there is no

THE BRAIN OF ORANG.

increased growth of the mental organ after Orang childhood, there may be great increase of the mus- 
cular structures. In the first instance, the brain case does not enlarge internally, and the old ones 
have no more brains than the young ; and in the second, the ridges on the skull, the spines of the 
neck, and the markings on the bones generally do grow immensely, so as to give attachment to 
extra muscular fibres. 
Moreover, besides these causes of growth there are those hidden ones which refer to sex, the old 
males acquiring a hideous aspect in our eyes, but lovely in those of the more comely female Miases, 
fi\ m the growth of long head ridges and the curious face pads. The bulk of the brain of an Orang is 
about one-half of that of a man of ordinary mind ; and the brain itself, whilst it is higher in measure- 
ment than that of any of the Apes already mentioned, is long and flat in comparison with that of man. 
In front it tapers off slightly, and is not flat in front and below, for there the eye-cases or orbits, by 
projecting upwards, render the brain in their neighbourhood, as it were, excavated. As in the other 
Apes, the back of the brain is well developed, and the several parts distinguishable in man exist. 
One of the furrows so visible in the Troglodytes, which marks the side of the brain towards the back 
(the occipito temporal) is scarcely in existence in the Orang. 
There is something very human in the appearance of the brain case in the young of both species 
of Orang, The back and sides have the peculiar “ bumpy” look of those of the child; there are then 
no crests, and the brow ridges, extremely small, merge into a straiglitish forehead. The face looks long 
in front of the eyes, or orbits, and these are elliptical or oval, and approaching the circular in outline.
