In regard to the expression of emotion among these Monkeys, 

 Mr. Darwin has recorded of different species that when pleased 

 they draw back the corners of the mouth in a species of smile, 

 become red in the face when angry, and pale when afraid. 



The term Macaque was given to these monkeys by Buffon, 

 who took it, however, from what is supposed to have been 

 the native name of an African species of Monkey, and 

 misapplied it to this Indian group. Macacus is therefore the 

 Latinised form of that word, which has now been applied too 

 long to be changed.
