which are manifestly of a lighter hue than the rest of the 

 body, and assume more of a pale coffee colour. The face is 

 completely surrounded by a circle of white hair, narrow across 

 the forehead, but expanded over the cheeks in the form of 

 large bushy whiskers, and extending beneath the chin so as to

Monkeys have cheek -pouches, callosities, and very long mus-

 Waterton says, of the American monkeys, that " those with 

 hairy and bushy tails climb just like the squirrel, and make no 

 use of the tail to help them from branch to branch. Those 

 which have the tail bare underneath, towards the end, find it of
