 pursued, and the limited time and opportunities he has had at his 

 command. 



Prof. Kamsay thanked the President and Council in the name of 

 Mr. Croll for the honour bestowed on him. He remarked that Mr. 

 CroU's merits as an original thinker are of a very high kind ; and 

 that he is all the more deserving of this honour from the circum- 

 stance that he has risen to have a well-recognized place among men 

 of science without any of the advantages of early scientific training ; 

 and the position he now occupies has been won by his own unassisted 

 exertions. 



The President then proceeded to read his Aniversary Address, in 

 which he discussed the bearings upon theoretical Geology of the 

 results obtained by the Eoyal Commission on Water- Supply and the 

 Eoyal Coal Commission. The Address was prefaced by biographical 

 notices of deceased Fellows, including Sir Roderick I. Murchison, 

 Mr. William Lonsdale, Sir Thomas Acland, Sir John Herschel, Mr. 

 George Grote, Mr. Eobert Chambers, Mr. C. B. Rose, and M. Lartet.
