This prospectus gives, for the first time, information as to the 
different forms in which the map was published. Although the pros- 
pectus begins " This day," it is not dated, not even the year being 
given, but presumably it should bear the same date as the map, viz., 
August 1, 1815. 
My second copy is evidently one of those described as " Price, in 
Sheets, with the Memoir, £5 5s. Od. It is in fifteen sheets, each measur- 
ing 23Jins. by 20 ins." The " Sketch of the Relative Succession of 
Strata and their Relative Altitudes," as in the previous map, bears 
the autograph signature of Wm. Smith ; in this case, however, with 
" No. 78 " added. Mr. C. Davies Sherborn informs me that the copy 
in the Natural History Museum, South Kensington, is signed, and with 
"a 61," and a further example just obtained from Messrs. Wesley 
& Sons, is numbered 96, so that it would seem that Smith autographed 
a number of his maps, but not all ; as a nearly complete copy of the 
map in the London Geological Society's library (which map is intact 
so far as this Section is concerned), contains neither signature nor 
number. A map recently for sale by Messrs. Wheldon is neither 
signed nor numbered. Another map, recently purchased by the 
National. Museum of Wales, is signed, and numbered b. 72. 
The fifteen sheets in this second map {i.e. No. 78), are carefully 
mounted on guards, and bound up in a contemporary half-leather 
cover. But it contains a map or an extra sheet, which I had not seen 
before.* This is headed ** General Map " and is a reduced facsimile 
of the large map, without the geological colours. It covers precisely 
the same area as the large map, and is divided into fifteen rectangles, 
I have since obtained a second copy of this " General Map.'*
