When left dirty or hungry, it would scream violently till attended to, 

 varied by a kind of pumping noise very similar to that which is made 

 by the adult animal. If its cries were taken no notice of, or no one 

 was in the house, it would lie quiet, but as soon as it heard a footstep 

 near it would recommence with great violence. In five weeks it cut 

 its two upper front teeth, but all this time it had not grown in the 

 least, remaining, both in dimensions and weight, the same as when I 

 first procured it. This was no doubt owing to want of milk or other 

 equally nourishing food. Rice water was a miserable substitute, and 

 cocoa-nut milk, which I sometimes gave it, did not quite agree with 

 its stomach. To this I imputed an attack of diarrhoea which the 

 poor little animal suffered, for which I gave it a small dose of castor- 

 oil, which operated very well, and it afterwards soon became better. 

 It was however again taken ill, and this time more seriously. The 

 symptoms were all those of intermittent fever accompanied with 

 watery swellings of 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." — P. 386. 



Mr. Wallace arrives at the following conclusions respecting the 

 orangs of Borneo : — 



"1. That two species of orang have been ascertained to exist in 

 Borneo. 



" 2. The difference between them are well marked in the males, but 

 much less distinct in the females. 



" 3. That all the females are characterized by the small-sized skull 

 without prominent ridges and by their subtruncated dilated canine 

 teeth. 



" 4. The males of both species possess large conical canines. 



" 5. That the form, size and proportions of the crania, and the size 

 and position of the teeth, vary in each individual to such an extent, 

 that these variations alone cannot be taken to mark distinct species. 



"Most of these conclusions are fully supported by Prof. Tem- 

 minck, from an examination of the very extensive series of specimens 

 in the Leyden Museum, though, from not possessing specimens of the 

 smaller male, he was unable to detect any specific difference in the 

 females."— P. 475.
