8 ANIMALS IN MENAGERIES. 



motions^ and the incessant iteration of their a-ies ; while 

 their amazing agility is well calculated to excite his 

 wonder. This celerity of motion is even conspicuous 

 under confinement : they are said^ even then^ to shoot 

 forward with such sustained vigour, as to make several 

 turnings in their course as if flying, sustained in the 

 air only by the impulse which they may receive from 

 striking the walls of their cage. This assertion, however, 

 may be reasonably doubted. When in captivity, their 

 voice is seldom heard, and then only in a dull feeble 

 sort of grunt. When young, they are docile, particularly 

 the females ; but in adult age they becom.e excessively 

 malicious : this extreme irritability prevents the species 

 from ever being completely tamed : gentleness fails, and, 

 if treated with violence or unkindness, he becomes 

 melancholy and soon dies. The extraordinary dexterity 

 of this species is shown in the use of their hands. If 

 a man, by any accident, loses his thumb, we see that the 

 main power of the hand is gone ; yet, notwithstanding 

 the extreme shortness of this member in the Malbrouc^ 

 it can seize, between the thumb and the fore-finger, the 

 smallest object with the most wonderful facility. In eat- 

 ing fruits or roots, these monkeys pull them with their 

 teeth, and smell every article of food before it is devoured; 

 in drinking, they suck : their senses, in all respects, are 

 extremely good, without being remarkably delicate, and 

 theyare evidently gifted with great powers of sight. 



The colour of the upper parts of the Malbrouc is olive 

 brown ; and of the under, including the throat, chest, 

 body, and internal parts of the limbs, dull white : there 

 is also a whitish band over the eyes. ^ The buttocks 

 have very large callosities : the tail is longer than the 

 body, and the cheek pouches are distinct.

Of this monkey there appears to be two races, or 

 possibly (according to Geoffroy) two species. Their
