or pumping noise, very similar to that which is made by the adult animal. If no one was in the house, or its cries were not attended to, it would be quiet after a little while, but the moment it heard a footstep would begin again harder than ever. After five weeks it cut its two upper front teeth, but in all this time it had not grown the least bit, remaining, both in size and weight, the same as when I first procured it. This was, no doubt, owing to the want of milk or other equally nourishing food. Rice-water, rice, and biscuits were but a poor substitute, and the expressed milk of the cocoa-nut, which I sometimes gave it, did not quite agree with its stomach. To this I imputed an attack of diarrhœa, from which the poor little creature suffered greatly, but a small dose of castor-oil operated well, and cured 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. I 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 increased growth of the mental organ after Orang childhood, there may be great increase of the muscular 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.
