sign them any high rank as instruments of human 

 progress. And those who beheve in the creation of 

 man by a personal God have been slow to believe 

 that He who took the bow in the clouds existing 

 from the creation, as the appointed symbol of his 

 promise to the race, has also taken animal powers 

 in man and put them to a higher and nobler use 

 than in any of the tribes below him. They need to 

 study the great plan of God's economy in creation 

 to learn that in each new form of life, nothing new 

 is introduced until the possibiHties of the old forms 

 have been exhausted. The hand of man is no less 

 wonderful or noble because it is foreshadowed in ; 

 the fin of the fossil fish of the Silurian age. 



As in the body of man we find the same sort of . 

 organs as in the lower tribes but fashioned for a 

 higher use than such animals can need, so in his 

 supersensual nature, we find the animal powers 

 ministering to a higher life than those tribes ever 

 possess. If there is a Comparative Anatomy there 

 is also a Comparative Psychology. It is only when 

 the comparison between men and animals is ex- 

 haustively made that we can reach that which is 

 distinctive of man. If we can find nothing distinc- 

 tive, then must we acknowledge him to be an ani- 

 mal in kind differing from the others only in degree. 

 If we would escape from this admission, we must 

 begin by granting to his animal nature all that be- 

 longs to it. When this is fairly done, what re-

 some hope of making good our claim.
