from Tree to Tree over my Head ; chattering and making a 

 terrible Noise; and a great many grim Faces, and shewing 

 antick Gestures. Some broke down dry Sticks and threw at 

 me; ... at last one bigger than the rest came to a 

 small Limb just over my Head ; and leaping directly at me 

 made me start back, but the Monkey caught hold of the Bough 

 with the tip of his tail ; and there continued swinging to and 

 fro, and making mouths at me. . . . The Tails of these 

 Monkeys are as good to them as one of their hands ; and they 

 will hold as fast by them. . . . The Females with their 

 young ones are much troubled to leap after the Males ; for 

 they have commonly two : one she carries under one of her 

 Arms, the other sits on her Back, and clasps her two Fore-Paws 

 about her Neck. These Monkeys are the most sullen I ever 

 met with, for all the Art we could use would never tame them. 

 . . . These Monkeys are very rarely or (as some say) never 

 on the Ground."
