PREFACE 
Tue essays included in this volume are a selection of 
occasional addresses which have been given during the 
last fifteen years on some of the topics that confront a 
man of science engaged in a modern university. They 
may be of interest in showing one aspect of the educa- 
_ tional campaign that is being carried on in these newer 
centres of learning. Like any collection of addresses, 
this one may weary by its repetitions and reiterations ; 
but on consideration it seemed better, and it has 
certainly been easier, to reprint the essays individually 
without alteration, than to attempt to combine them 
into a more systematic treatise on science and educa- 
tion. The concern of the author, it will be seen, has 
been to raise his voice equally against pedantry and 
Philistinism, the Scylla and Charybdis through which 
our Universities need to-day such careful steering.
