teen did not show uniform elimination, i.e., fourteen per cent 

 were progressive, nine per cent possibly progressive and seventy- 

 seven per cent not progressive. 



There were three cases where IV and V were eliminated before 

 II and III or fourteen per cent. 



The averages do not show progressive elimination nor were 

 IV and V eliminated before II and III. 



We do find, however, in every group that alley II is nearly 

 always the last to be eliminated. A possible explanation of this 

 has already been offered on page 67. The results in alleys III, 

 IV and V are so nearly identical that the three may be con- 

 sidered as eliminated at practically the same time. 



From these experiments it seems fairly probable that the rapid- 

 ity with which a given co-ordination in a complex habit is formed 

 is not proportional to the distance from the point at which 

 the co-ordination takes place to the point at which food is to 

 be obtained.
