at the offenders, uttering hollow barks at intervals. This sound seemed 

 to be used for the purpose of expressing irritation. Anger was expressed 

 by the shrieking "Ra! ra!" and pleasure by a kind of mixture between 

 a squeak and a chirp. 



Wallace had a Siamang that used to play with liis native servant. 

 Hence we may conclude that this genus does not deserve the charactei 

 given it by some authors who describe it as a dull and stupid animal, 

 that does not care to distinguish between friend and foes, that will not 

 move till forced to do so, hardly even taking the trouble to put its food 

 into its mouth. 



Mr. Bennett the English naturalist confirms Wallace's account of the 

 gentleness of this species. He writes : " Going into the courtyard where 

 Ungka was tied up one morning, I was sorry to see it occupied in trying 

 to get rid of its waist-belt and rope, while at the same time it uttered a 

 sharp, plaintive cry. When unfastened, it went towards a group of 

 Malays, and after catching hold of the legs of some of them, it ap- 

 proached one who was lying down, jumped on him, and closely embraced 

 him witli an expression of recognition. I learned that this man in whose 

 arms the Monkey showed so much pleasure, was its first master." 



Mr. Bennett adds that Ungka preferred vegetables, such as rice and 

 onions, to flesh. She drank tea, coffee, and chocolate, but never wine or 

 spirituous liquors.
