32 ON- THE RELATION OF NATURAL SCIENCE. 



most intimately connected with psychology, inasmuch as 

 physiology traces in our sensations the results of mental 

 processes which do not fall within the sphere of con- 

 ciousness, and must therefore have remained inaccessible 

 to us. 



I have been able to quote only some of the most 

 striking instances of this interdependence of different 

 sciences, and such as could be explained in a few words. 

 Naturally, too, I have tried to choose them from the most 

 widely-separated sciences. But far wider is of course the 

 influence which allied sciences exert upon each other. 

 Of that I need not speak, for each of you knows it from 

 his own experience. 



In conclusion, I would say, let each of us think of him- 

 self, not as a man seeking to gratify his own thirst for 

 knowledge, or to promote his own private advantage, or 

 to shine by his own abilities, but rather as a fellow- 

 labourer in one great common work bearing upon the 

 highest interests of humanity. Then assuredly we shall 

 not fail of our reward in the approval of our own con- 

 science and the esteem of our fellow-citizens. To keep 

 up these relations between all searchers after truth and 

 all branches of kno"wledge, to animate them all to vigo- 

 rous co-operation towards their common end, is the great 

 office of the Universities. Therefore is it necessary that 

 the four Faculties should ever go hand in hand, and in 

 this conviction will we strive, so far as in us lies, to press 

 onward to the fulfilment of our great mission.
