Z. UNCLASSED RESIDUUM. 



We now come to the final group, namely, 

 those influences which cannot be sorted into any 

 of the 8 groups with definite titles, which we 

 have already examined. At the outset I spoke 

 of these unclassed conditions as forming a class 

 by themselves, of no great importance, and 

 which might be indefinitely reduced in pro- 

 portion as we chose to pursue our analysis. I 

 estimate that the 91 replies which I have re- 

 ceived and analysed assign a total of 191 causes. 

 It now appears that no less than 188 of these 

 fall into one or other of 8 definite groups, and 

 that there remahi only 3 on our hands for the 

 unclassed residuum. Even these are apparently 

 due to aggregates of conditions, the more im- 

 portant of which would probably find their place 

 among the 8 groups, leaving a still minuter 

 residue.. We may lightly dismiss them as of 

 inappreciably small importance in our present 

 inquiry.
