genious philosopher who propoimds an entirely faulty system may 

 be an important factor in.the advance of truth through the sharpening 



of the mental faculties of his critics by analyzing his system, pointing 

 out its defects, ami cither correcting his results, or putting them into 

 proper shape. Since the time of the schoolmen it has beer recognized 

 that the analysis of fallacies is one of the best methods of discipline in 

 the art of correct reasoning. 



The arrangements made by the authorities of the fair for enabling 

 the scientific men of our country to avail themselves of the advantages 

 of this remarkahle assemblage and to listen to its discussions have been 

 of the most liberal kind. Noiadmission fee is required other than that 

 to the fair itself, and the meetings are open to all known to be inter- 

 ested, so far as room can be found. The attendance of members of 

 national scientific societies and professors in colleges and universities 

 and scientific men generally is especially desired. Whether room can 

 be found for all who wish to attend can not be known until the wishes 

 of more are heard from. Subject to this condition, every professional 

 scholar and scientific teacher or investigator is welcome to avail him- 

 self of an opportunity which may not recur in a lifetime.
