gree forms one of the difficulties of statuaiy, and 

 requires, on the part of the artist, a constant at- 

 tention to this property of his work, distinct from 

 every other. 



It is the most difficult thing that can be to get 

 a wig made even ; yet how seldom is the face 

 awiy ! And what care is taken that it should not

This regularity of the animal structure is ren-
