VIII UNIVERSITIES : ACTUAL AND IDEAL 227 



The obligation to produce results for the in- 

 struction of others, seems to me to be a more 

 effectual check on these tendencies than even the 

 love of usefulness or the ambition for fame. 



But supposing the Professorial forces of our

 the wants of learners ? In answering this ques- 

 tion, I confine myself to my own province, and I

 and undoubtedly, No. As I have already intimated, 

 practical work in the Laboratory is absolutely 

 indispensable, and that practical work must be 

 guided and superintended by a sufficient staff of 

 Bsmonstrators. who are for Science what Tutors 

 are for other branches of study. And there must 

 be a good supply of such Demonstrators. I doubt 

 if the practical work of more than twenty students 

 can be properly superintended by one Demon- 

 strator. If we take the working day at six hours, 

 that is less than twenty minutes apiece not a

 of a proper amount of this tutorial, practical
