CHAPTER III. 



1834-1849. 



GEOLOGY OF COALBROOK DALE AND GAMRIE 

 TERTIARY MEMOIRS. 



THE early part of 1834 was spent in Ireland, and the 

 later spring months in Scotland. The result of the 

 northern journey was a paper read in 1835 before the 

 Geological Society, " On the Ich thy elites of Gamrie in 

 Banffshire," which, though written subsequently to the 

 Goalbrook Dale Memoir, was yet his first published 

 work, as it appeared in an abridged form in 1835. 

 This paper was supplemented by another in 1837, in 

 which was first noticed the occurrence of shells in the 

 Till at high levels and separate from raised beaches. 

 The two papers were published in full in 1840. 



We are unable to ascertain to whom the following 

 letter was addressed. It is quoted merely to show 

 the care which the young geologist evinced in replying 

 to any inquiry :
