Vol. 59.] ANNIVERSARY MEETING LYELL MEDAL. xli 



Caradoc area and elsewhere, but introduced into the geological 

 literature of our older rock-groups the names Uriconian, 

 Longmyndian, and Malvernian. 



Your researches also in the Malvern Hills, in Anglesey, and 

 in the complicated Assynt and other regions of the North-Western 

 Highlands were all of them most fruitful in discovery, and stimu- 

 lated the work of others in no ordinary degree. And of your 

 later researches into the obscure phenomena of the crystalline 

 and metamorphic rocks, the same may be said. As one of those 

 who have followed your track, to their pleasure and benefit; 

 and as one who has for more than thirty years been honoured 

 by your friendship, it is a great pleasure to me to be permitted 

 to hand you this Medal on behalf of the Council of the Geological 

 Society. 



Dr. Callaway replied as follows : — 



Mr. President, — 



I am deeply sensible of the honour conferred upon me by the 

 award of this Medal. It is to me a special gratification that it 

 bears the name of Murchison, for the greater part of my work has 

 been on ground rendered classic by his genius. We honour him as 

 one of the chief of those who laid the foundations of our knowledge 

 of the oldest rocks, and I am proud to have been able to add a few 

 stones to the superstructure. That I receive this distinction at 

 your hands is a peculiar pleasure. You also have laboured long in 

 the field of Archaean and Proterozoic geology. Your kind and 

 generous appreciation has, therefore, a personal, as well as an 

 official, value. 



Award oe the Lyell Medal. 



In presenting the Lyell Medal to Mr. Frederick William Rtjdler, 

 late Curator of the Museum of Practical Geology, Jermyn Street, 

 the President addressed him as follows : — 



Mr. Rudler, — 



Our science demands for its progress not only men who discover 

 new facts, but also men who will explain and illustrate its facts 

 and theories to those who are anxious to understand and to make
