ENVIRONMENT AMONG MEN 355 



the results of selection under the heading of the influence of the 

 environment is somewhat misleading. Selection is a wholly 

 different matter and, unless it is carefully distinguished from 

 other factors, confusion of thought results. The effects which 

 follow from elimination owing to climate and food should not 

 be summed up under the heading of the influence of the environ- 

 ment ; in this book they are considered in Chapters XVII and 

 XVIII.
