The final object of the Geological Survey is to arrange, in a 
form easily accessible to the public, a complete body of informa- 
tion respecting the true geological structure of the British islands 
and the disposition and the extent of their mineral wealth ; 
such information, as it is obtained, has been and will continue 
to be, incorporated in the publications of the Survey, which 
consist of : — 
1. Geological Maps based upon those prepared by the Ordnance 
Survey, and exhibiting the distribution of the strata. 
2. Geological Sections exhibiting the order and mode of 
superposition of those strata, along particular lines of the districts 
surveyed. 
3. Explanatory Descriptions accompanying and elucidating 
the maps and sections. 
4. Memoirs , which comprise : 
a. Detailed geological, mineralogical, and metallur- 
gical essays upon questions of importance connected 
with the structure or the mineral products of the 
country. 
b. Illustrated monographs and decades descriptive 
of new, or otherwise important, fossil remains which
