Chap. II.] MENTAL POWERS. 61

 more than once daring the interval of five years. This 

 dog might have brought forward the argument lately ad- 

 vanced to crush all evolutionists, and said, " I abide amid 

 all mental moods and all material changes. . . . The

 other atoms falling into the places they have vacated is 

 contradictory of the utterance of consciousness, and is

 gayly-colored objects, as do certain humming-birds their 

 nests, offer additional evidence that they possess a sense
