 and likewise when pleased. But neither the degree of 

 protrusion nor the shape of the month is exactly the

 drawing represents a chimpanzee made sulky by an 

 orange having been offered him, and then taken away. 

 A similar protrusion or pouting of the lips, though 

 to a much slighter degree, may be seen in sulky chil-
