218 MAMMALIAN DESCENT. [LECT. IX. 



When the dust of controversy ' shall have subsided, 

 when those who have to receive new ideas as if by a 

 surgical operation begin to feel the stirrings of these 

 new conceptions thus let into them^the " new leaven " 

 of nobler thoughts about nature, and of the great First 

 Cause of nature then all who can think will find that 

 they are colonising a " new Atlantis." 



The "old song" of the creation puts it thus, 

 " Evening was morning was, day one." 



Thus the shadows of evening come first, and the rosy 

 light of dawn afterwards. Now, in science, even in 

 biological science, the "morning is spread upon the 

 mountains," and soaring birds are singing at heaven's 

 gate ; so that the drowsiest folk are beginning to stir 

 themselves, " ere well awake."
