Abstract
OF the new series one-inch map of England and Wales, few sheets are of greater interest than No. 352 (colour-printed, price 1s. 6d.), which represents that portion of western Cornwall that contains the oldest and richest mines in the county; and the value of the map is greatly enhanced by the admirable explanatory memoir, which contains a description of the older slaty rocks, the granites, elvans, and greenstones of this area, together with particulars of the metalliferous veins. Attention is given to the genesis of the ores, and to their mode of occurrence, to the methods of dressing the tin ore, and to the mineral output. In short, the description is much more detailed than is usual in a Geological Survey sheet explanation.
