SAGACITY OF THE TITI MONKEY. 199 



till after a long period. It has been supposed that 

 this usage prevents the Indians from being stung by 

 insects ; but this was found to be incorrect. The 

 preference given by the American tribes to the red 

 colour, Humboldt supposes to be owing to the tend- 

 ency which nations feel to attribute the idea of 

 beauty to whatever characterizes their national

The encampment of Pararuma also afforded the

 Humboldt. He mentions a very interesting fact 

 illustrative of the sagacity of this creature. One 

 which he had purchased of the natives distinguished 

 the different plates of a work on natural history so 

 well, that when an engraving which contained zoo- 

 logical representations was placedbefore it, it rapidly 

 advanced its little hand to catch a grasshopper or a

 to form part of the crew were chained during the 

 night to prevent their escape ; and on the morning
