212 Zoology as Related to Evolution. 



" 'Tis not in the high stars alone, 



Nor in the cups of budding flowers, 



Nor in the redbreast's mellow tone, 



Nor in the bow that smiles thro' showers, 



But in the mud and scum of things 

 That alway, alway something sings ! " 



II. Passing now from what zoology has-been historically 

 as an embodiment of evolution to what it is scientifically as 

 a field for it, how widely already has it opened its gate for 

 its entrance ! It is not indeed the whole of its sphere. The 

 starry heavens, the rock-ribbed earth, the chemical elements, 

 the vast realm of botany, and who shall say how largely the 

 kingdom of mind, are other rooms in its great house. But 

 it is one of its most important departments one that, with 

 the great mystery of life already its occupant, it seemed be- 

 forehand almost impossible for it to enter. All its great 

 fundamental principles homogeneousness at the start, dif- 

 ferentiation, rhythmic movement, the multiplication of 

 effects, integration, and then dissolution and the use of its 

 materials over again in a new series all these, with some 

 others, as natural selection, peculiar to its own realm, it 

 illustrates with marvelous beauty alike in the individual 

 and the race, evinces it as holding good in the realms of' 

 flesh and life as well as in those of matter and force, shows 

 that what made the star made the soul, that what or- 

 ganized the earth organized its inhabitants, and that the 

 highway of creation trod out of primal fire-mist over whirl- 

 ing atom, tenuous nebula and blazing sun, over cooling 

 planet, heaving continent and quaking rock, was not ended 

 or interrupted when it came to man and mind. It is not 

 strange that to the world at large Darwinism means the 

 same thing as evolution. Without the Origin of Species to 

 lead the way it is doubtful whether The First Principles of 

 a New Philosophy would have ever got beyond the scholar's 

 study. It was its victory on the field of zoology that 

 forced it into the ears and faith of the general public. 

 With the citadel of life carried by its logic and the myriad 

 armies of the animal world made its captives, it was felt 

 that the whole vast fort of the universe might as well be 

 surrendered to it at once as wait for an assault it now be- 

 came certain nothing could resist. And so, if Spencer is to 

 be regarded as the Messiah of evolution, Darwin must be 

 set down as at least its Apostle Paul. 



What a field, too, it affords for its further progress ! Dar-
