Appointed at first to judge of and to fix the classification-scliedules, 

 the Provisional International Committee has at the same time been 

 invested with the extensive power of taking resolutions on different 

 questions left undecided by the conference, regarding the construction 

 of the catalogue. This committee will have to frame a report, not 

 later than July 31^* 1899; which will be incorporated in the deci- 

 sions of the conference. 



It cannot be denied that llie task of this International Committee 

 is a heavy one. In order to render it somewhat easier and to give 

 to all opinions an opportunity of making themselves heard, the de- 

 legates have been charged with the formation of local committees, 

 each in his own country, to consider the questions left undecided 

 and to report there on to the International Committee within six 

 months. 



In my opinion these committees will indeed be able to do useful 

 work. For if it might appear that there was but little difterence of 

 opinion on matters of importance, the decisions of the International 

 Committee would certainly be facilitated. The clear exposition of the 

 different questions in the report of the Royal Society-Committee raises 

 a well founded expectation that such concordances will take place. 



I venture to express the hope, that the Committee of our Academy, 

 which has already formerly occupied itself with the International 

 Catalogue, will by its cooperation enable me to fulfil this part of 

 my charge. 



Conformable to the above the President pi'omises again to con- 

 vocate the Committee which has on former occasions given advice 

 on the International Cataloeue.

§ 1. Introduction. 



The present physiology of the cortex of the brain justly attaches 

 great importance to the idea of association. Since it has been proved 

 that different functions may be ascribed to different parts of the 

 cortex of the brain, it has become necessary on anatomical grounds 

 to suppose connections between those parts, moreover to assume on 

 clinical grounds, that in psychical processes these connections are used.
