1841 DUTIES OF GEOLOGISTS 43 



wards into Pembrokeshire, and was at work at Tenby, 

 and St. David's, and the neighbourhood. There 

 were then four assistants besides myself.' 1 



Over and above the ordinary assistants, however, 

 the Survey was aided in the palaeontological depart- 

 ment by Professor John Phillips a name affectionately 

 remembered by those who knew him, and honoured 

 by all to whom the history of British geology is 

 familiar. 2 Phillips had previously been employed to 

 examine, figure, and describe the organic remains in 

 the older rocks met with in the course of the survey of 

 Cornwall, Devon, and West Somerset, and an im- 

 portant monograph giving the results of his labours 

 appeared in 1841 as a sequel to the Report of De la 

 Beche. 3 Before the publication of this work, however, 

 the field-operations of the Survey had extended into 

 South Wales, and Phillips in 1840 received an 

 appointment to extend his task into East Somerset, 

 Gloucester, Monmouth, and South Wales. He was 

 in Pembrokeshire when Ramsay joined the staff, and 

 they had some excursions together. 



The duties of the geologists in the Geological 

 Survey were to trace on the one-inch maps of the 

 Ordnance Survey the boundaries, structure, and 

 relations of the various geological formations, to 

 collect as much information as possible regarding the 

 nature of the rocks and minerals, to mark where any 

 substances of economic value might be found, to follow

 Apparatus, South Kensington Museum, 1876, p. 364. The four assistants 

 referred to above were W. T. Aveline, who joined the service the year before 

 Ramsay, retired from it the year after him, and now lives in Somerset ; Trevor 

 E. James, D. H. Williams, and J. Rees.
