196 The Evolution of Mind. 



est manifestation of mental life. The mind tlironghout its 

 whole developmental career has been reaching toward it 

 and longing for it. All progress is and always has been in 

 its direction. The gentle mother of all sings to us its 

 lullal)y, and our nervous systems are steadily being attuned 

 to the refrain. 



The following apostrophe was written many years ago, 

 but has not before been published. It accords with the 

 line of thought which properly terminates my discussion 

 of this topic. 



Thrill on, O mystic neural threads ! 



Your sym])athetic jiulse is heaven 

 When wave with wave enraptured weds 



And hearts attractive bonds are given. 



Attuned to God's divinest notes, 



Yon stars such symijhonies are sounding ; 



And atom unto atom quotes 



This rhythmic cadence when rebounding. 



Y'our quivering structures tell of love. — 

 The highest, purest, grandest motion ; 



Your psychic transports soar above 

 Into the great supernal ocean. 



Yes, throb in unison with all, 



To form a perfect diapason. 

 That echoing concords may recall 



Thy tender, sanctified sensation.
