CATALOGUE OF THE GOVEENMENT SURVEY MAPS AND 
SECTIONS. 
The following list cannot fail to be of utility to every practical geologist as a 
table of reference, and its usefulness wUl be felt by others, who are, perhaps, in 
ignorance, as many undoubtedly are, of even the existence of these valuable 
geological maps and sections. 
The reason of such ignorance is, probably, that Her Majesty's Government do 
not allow usual trade-commission to the booksellers, who wiU not, therefore, obtain 
them, except for such good customers as they cannot refuse, as these publications 
bring to them no profit, and often incur actual expense. 
Provincial geologists, moreover, find it no easy matter to ascertain what 
portions of the country have been examined, and plotted, and coloured upon the 
ordnance maps, by the Government ofiicers, and it is still more difficult to obtain 
information of the sections, and of the " decades " of fossils. 
The publications enumerated below are not only of geological, but of great 
national value, and it is therefore very desirable to make knowni to our readers 
that they can be obtained in London, of Mr. Stanford, mapseller and publisher. 
Charing Cross ; of Messrs. Longman, the Government publishers. Paternoster 
Row; and of Messrs. Letts and Son, Royal Exchange. 
By the courtesy of Mr. Stanford we are enabled to append to this paper a 
reduced index map of the divisional portions of the survey, which will greatly 
facilitate the object of this catalogue. 
THE GEOLOGICAL MAP AND SECTIONS OF ENGLAND AND 
WALES. 
The maps are on the scale of one inch to a mile. They are the Ordnance maps, 
specially adapted and coloured geologically, imder the superintendence of the 
Director- General of the Survey. 
The longitudinal or horizontal sections are on separate sheets, on a scale of 6 
inches to a mile. 
The vertical sections are on a scale of 40 feet to an inch. 
The map is divided into 110 divisions or sheets, about 50 of which are published, 
and 20 in progress of survey. 
Some of the maps are printed in a single sheet, 27 inches by 40 — others in 
quarter sheets. 
The price of the Geological Maps is 2s. 6d. per quarter sheet, and 6s. per sheet 
except where the sheet is chiefly occupied by sea, when it is Is. per sheet.
