340 INDUCTION. 



What more may usefully be said 011 the subject of Colliga 

 tion, or of the correlative expression invented by Dr. Whewell, 

 the Explication of Conceptions, and generally on the subject 

 of ideas and mental representations as connected with the study 

 of facts, will find a more appropriate place in the Fourth Book, 

 on the Operations Subsidiary to Induction : to which I must 

 refer the reader for the removal of any difficulty which the 

 present discussion may have left.
