Five years ago, Mr. Bartholomew, who had with great labour constructed from the sheets of theO rdnance Survey a general topographical map of England and Wales on the scale of ten miles to an inch, expressed to me his willingness to employ the same plates for the production of a geological map of the country, if I would superintend the reduction from the published maps of the Geological Survey. His map is so good as a general topographical representation of the country, that it appeared to me likely to prove convenient and useful if the geology were inserted on it. A ccordingly, his proposal was eventually carried into effect, and the map so prepared is now issued to the public. While the reduction has been made by Mr. Bartholomew sable assistant, Mr. Bosse, it has been repeatedly revised by some of my colleagues in the Geological Survey, as well as by myself. The late Mr. W. Topley, F.R.S., took a large share in the early stages of this labour, and since his death the task has been carried on by Mr. H. B. Woodward, F.R.S., Mr. W. Gibson, and Mr. W. W. Watts. I have drawn theS ections which are placed round the borders of the map to explain the geological structure of the country. The following brief Notes are intended merely for the general reader or traveller who may have no special geological knowledge, but may be induced to take the map with him as a convenient guide in journeying across the country. The meaning of the various colours and the nature of the rocks they represent are here briefly explained. A cursory glance at a geological map of England and Wales reveals some of the fundamental features in the geology of the country. In the first place, it shows that a line drawn in a nearly north and south direction from the coast of Durham, about the mouth of the Tees, to that of Devon, at the mouth of theE xe, divides the region into two parts.
