render oneself liked, to earn the half-contemptuously endearing 

 title — "a good fellow; " and if a man should give his mind to it, 

 it might not prove hard, say hy a course of consistent sternness, to 

 make himself feared; but what is difficult, and consequently an 

 attainment very rare, is so to enlist the sympathies of pupils as to 

 awaken an affection tempered with respect — a respect softened with 

 affection. To those who do this for us no tribute of gratitude can 

 be too great ; they satisfy a desire deeply implanted in our being, 

 of having someone to whom we can look up, whose blame we fear, 

 whose approval is labour's best reward. 



Mr. Teall has said that Professor Bonney made of him a geologist; 

 and as I reflect on this it seems to me that scarcely any living 

 teacher has made so many geologists as Professor Bonney : at 

 Cambridge he used to manufacture on an average about one 

 a year; sometimes, indeed, it was more, for I remember Jukes- 

 Browne went out in the same year that I did : and as some 

 of us have taken to producing geologists ourselves, the rate of 

 increase of Professor Bonney's students and their descendants 

 becomes a problem like the old question of the peopling of the world 

 by Adam and Eve. It is not surprising then to find Professor 

 Bonney's students in all quarters of the habitable — and not 

 everywhere habitable — globe. As I left Dublin I encountered 

 one — La Touche — who had just returned from unravelling the 

 difficult structure of Scinde. Professor Bonney's students are not 

 only to be found in different regions of this terrestrial sphere, but in 

 various provinces of thought : some who walked with him for a 

 while in Geology, studying the wholesome rocks, have deviated into 

 Zoology, and devote themselves to the lower animals and the ways, 

 not always wholesome, of mankind ; but these still remember, 

 perhaps sadly, their days of grace, and are proud to recall that they 

 too were once students of Professor Bonney's. I cite as an example 

 Professor Haddon, and would add as an instance of a strayed 

 botanist. Professor Hartog, were he not a man too various to be so 

 epitomised : he too left Cambridge in the same year with me, and 

 that perhaj)s is the reason he did not become a geologist, for it 

 would be beyond nature to make three geologists in one year. 

 And while talking of the making of geologists, it is fitting to
