 refined and, delicate taste and feelings, yet genial, courtly, 

 lavishly hospitable, always prone to look at the kindly and 

 humorous aspect of things. Those who knew him best now 

 feel that his loss has made in their lives a lasting void.

Introduction. 



Much of the work of modern geology consists in the filling- 

 in of outlines. The day is almost past, in Britain at least, 

 for happy generalisations from rapid surveys. The generali- 

 sations of the future are to be the ^vork of men who have 

 mastered with minute fidelity the alphabet and dictionary of 

 the science. The every-day w^ork of geologists is to be a 

 modest elaboration of detail upon a ground-work of outline 

 long ago drawn out by the master-hands of the past.
