part 2] ANNIVERSARY MEETING MURCHISON MEDAL. xlv 



Looking back over many years' work at Geology, I am glad to 

 bear witness to the great advantage that I have reaped from the 

 work of those who have gone before me, and to acknowledge 

 the great help that I have received from the many living workers 

 in the various branches of our science, among whom I have spent 

 the greater part of my life. Old and young, I thank them all. 



Should what work I have done be of like service to those who 

 follow me, I shall not have lived in vain. 



It is one of the most pleasing prospects of old age to see that 

 there are younger men able and willing to take up the work which 

 we older men have to drop, and, looking around me, I salute the 

 Medallists of the future. 



Since my retirement from the Geological Survey, more than 

 a quarter of a century ago, my work has, of necessity, been largely 

 limited to applications of our science to more or less practical 

 purposes. In this I have been associated with chemists, engineers, 

 and others, from whom I have learnt much as to the bearings of 

 various sciences on each other, and whose help I am glad to 

 acknowledge. To the continuance of this help I am still looking 

 forward. 



I thank the Council for this, the third Medal which it has 

 awarded to me. I thank you, Sir, for the very kind words with 

 which you have given me the Medal, and I thank all my friends 

 for the way in which they have marked their approval of the 

 award. 



Award op the Murchison Medal. 



The President then presented the Murchison Medal to^ 

 Prof. John Joly, F.R.S., addressing him as follows : — 



Dr. Jolt, — 



It is with peculiar pleasure that I hand the Murchison Medal 

 to a Professor and Fellow of Trinity College, Dublin — a foundation 

 for which, not only as in private duty bound as an honorary 

 graduate, but also on other grounds, I have an affection. Your 

 contributions to science have been many and varied : at once a 

 physicist and a geologist, you have by your researches happily 

 united the two sciences, and in so doing you have displayed un- 

 ceasing industry, remarkable fertility for invention, elegance in
