In our work on the nerve components we have endeavored 
to live up to these ideals. In so far only as we succeed in ef- 
fecting wide and stable correlations from both the anatomical 
and the physiological side can we hope to be able to build a 
structure which shall endure as a secure foundation for an ulti- 
mately complete functional subdivision of the nervous system.
