EDINBURGH. 4 1 



one day have been thus honoured, I declare that I 

 should have thought it as ridiculous and improbable, 

 as if I had been told that I should be elected King 

 of England. 



During my second year at Edinburgh I attended 



's lectures on Geology and Zoology, but they 



were incredibly dull. The sole effect they produced 

 on me was the determination never as long as I lived

 it now lay. This produced a deep impression on me, 

 and I meditated over this wonderful stone. So that 

 I felt the keenest delight when I first read of the 

 action of icebergs in transporting boulders, and I

 is the fact that I, though now only sixty-seven 

 years old, heard the Professor, in a field lecture at 

 Salisbury Craigs, discoursing on a trap-dyke, with 

 amygdaloidal margins and the strata indurated on 

 each side, with volcanic rocks all around us, say 

 that it was a fissure filled with sediment from above, 

 adding with a sneer that there were men who main-
