1 845 REORGANISATION OF THE SERVICE 67 



Survey ever possessed, had joined as far back as the 

 summer of 1843. Charles R. Bone was employed as 

 artist to draw fossils described by the palaeontologist. 



With this augmentation of the staff, other addi- 

 tional duties were undertaken by the Survey. Of 

 these perhaps the most important was the preparation 

 and publication of Memoirs illustrative of various 

 districts that had been mapped, and containing a 

 discussion of subjects connected with general views 

 of geology and its applications. The first volume of 

 this series was soon planned. The Director-General 

 undertook to contribute an essay ' On the Formation 

 of the Rocks of South Wales and South -Western 

 England.' Edward Forbes supplied his famous and 

 classic paper * On the connection between the dis- 

 tribution of the existing fauna and flora of the 

 British Isles, and the geological changes which have 

 affected their area, especially during the epoch of the 

 Northern Drift.' Ramsay's contribution consisted of 

 his essay * On the Denudation of South Wales and 

 the adjacent counties of England.' The volume con- 

 taining these various papers appeared in 1846, and 

 the preparation of the material occupied much of the 

 time spent indoors in the previous year. 



The general bearing of the scientific organisation 

 planned by De la Beche upon the progress of geo- 

 logical investigation was well expressed by Leonard 

 Horner 1 in his address as President of the Geological 

 Society. * With scarcely any exceptions,' he said, 

 ' all geological inquiries have [hitherto] been the 



that he was eventually attached to the staff of the Survey. A large part of the 

 fossil collections in the Museum of Practical Geology was originally collected by 

 him. His name will frequently occur in the subsequent pages of this Memoir. 

 He retired from the service on a pension in 1872, and died in 1878.
