and the Grivet ; and frequently the companion of the 

 organ-grinder will be found to be one of the three. 



GREEN MONKEY (Cercopithecus sabceus). 

 Coloured Plate III. Fig. 2. 



The Green Monkey, a native of Western Africa, is one 

 of the commonest of imported monkeys. It is a handsome 

 species, in colour a general olive-green, as its name denotes, 

 with black hands and face ; the hairy fringe at the sides of 

 the face is almost a golden yellow. The greenish tinge is 

 particularly noticeable when the sun shines on it. Under 

 the microscope a single hair is seen to be really yellow with 

 bluish black bands at intervals ; and thus the green is but 

 the optical blending of two separate colours ; and by means 

 of coloured liquids a child can easily demonstrate that blue 

 and yellow, when mixed, produce green. 



PIG-TAILED MACAQUE (Macacus nemestrinus). 

 Plate II. Fig. i. 



The Macaques are tolerably well known animals, various 

 species of which are plentiful in the lands which they 

 inhabit, and they lend themselves with considerable readi- 

 ness to domestication. Being hardy of constitution, they 

 are often seen in our own country, and share with the Green 

 Monkey and its kin the doubtful privilege of being exhibited 

 and taught to perform various tricks. Two of the best 

 known are the Rhesus or Bhunder Monkey (Macacus rhesus) 

 and the Bonnet Monkey (Macacus radiatus). 



The Pig-tailed Macaque is trained by the natives of the 

 Far East not only to climb cocoanut trees, but also to select 

 with great care the ripest fruit and throw it to the ground 

 below, where it is collected and stored by the animal's 

 trainer and owner. The animal receives its name from the 

 fact that its tail is short and slender and bears more than 

 a little resemblance to that of a pig.
