382 FRAGMENTS OF SCIENCE. 



knowledge, as a tiling good in itself, anj.1 without regard 

 to its practical application, which animates the hearers of 

 these lectures. 



It is also my privilege to lecture to another audience in 

 London, composed in part of the aristocracy of rank, while 

 the audience just referred to is composed wholly of the 

 aristocracy of labor. As regards attention and courtesy to 

 the lecturer, neither of these audiences has anything to 

 learn of the other; neither can claim superiority over the 

 other. It would not, perhaps, be quite correct to take 

 those persons who flock to the School of Mines as average 

 samples of their class; they are probably picked men

 at Nottingham, last year, where the workingmen, at 

 their own request, were addressed by our late president, 

 Mr. Grove, and by my excellent friend, Professor Huxley,

 town in which the meeting is held. A resolution to that 

 effect was sent to the Committee of Recommendations; 

 the Committee supported the resolution; the Council of 

 the Association ratified the decision of the Committee; 

 and here I am to carry out to the best of my ability their 

 united wishes. 



Whether it be a consequence of long-continued develop- 

 ment, or an endowment conferred once for all on man at 

 his creation, we find him here gifted with a mind curious
