54 Geological Survey of the United Kingdom. [January, 
with two assistants, have the naming and arranging in the 
museum at Jermyn Street of the fossils collected on the 
Geological Survey of Eagland and Wales. 
The results of the Survey operations will be learnt from 
the published maps, memoirs, and sections. ‘The following 
statistics show the present state of the progress of the 
Geological Survey. 
The whole of Wales has been completed on the one-inch 
scale, while in England twenty-five counties have been 
finished. The area which remains to be surveyed comprises 
portions of Northumberland, Cumberland, Westmoreland, 
Durham, Yorkshire, Lancashire, the Isle of Man, Lincoln- 
shire, Nottinghamshire, Leicestershire, Cambridgeshire, 
Huntingdonshire, Norfolk, Suffolk, and Essex. In England 
and Wales, which comprise 110 sheets, 80 complete sheets 
have been published on the one-inch scale ; while numerous 
maps on the scale of six inches to one mile have been pub- 
lished to illustrate the coal-fields of Yorkshire, Northumber- 
land, Durham, and Lancashire. A number of sheets adja- 
cent to the Yorkshire coal-field, and not intended for 
publication, are deposited for reference at the Geological 
Survey Office, where they can be seen, and (under certain
