teachers and investigators or as industrial chemists, 

 and who, one and all, will, I know, acknowledge that 

 the first and most important step in that career was 

 the original work done for the Dalton Scholarship. 



The stimulus to original work must be given by the 

 teacher, and it is he only whose head, hand, and heart 

 are thus occupied who can induce others to follow the 

 same difficult though delightful path. In short, the 

 spirit of research must be felt in the atmosphere of the 

 laboratory, and in this respect there ought to be no 

 difference between pure science and its applications. 

 To prosecute either one or the other with success the 

 methods of research must be learnt and followed. 



This training in one science, however complete in 

 itself, is insufficient to educate a chemist whether for 

 theory or practice. For each of these branches of the 

 science a much fuller training and a much wider 

 scientific outlook are nowadays indispensable. The 

 chemist must know his mathematics ; his acquaintance 

 with physics must be sound and extensive ; engineering 

 in some of its branches must be studied, whilst a 

 knowledge of French and German is now absolutely 

 necessary to follow the progress of science abroad. At 

 every turn in his chemical work he meets with points 

 for the decision of which it is necessary for him to be 

 well versed in subjects which some years ago were 

 considered quite foreign to his scientific outfit. Thus, 

 if the new and important subjects of physiological and 

 pathological chemistry are to be followed, a study of 

 the biological sciences is necessary. Hence it is that 

 colleges and universities which set out to train men in 

 science have formulated a strict and properly graduated 

 series of courses, giving the student an opportunity of 

 acquiring a knowledge of the collateral subjects with 

 which he may afterwards be called upon to deal.
