THIS Catalogue contains a list of geological photographs taken during the past twenty years as a part of the work of the Geological Survey of . Negatives, prints, lantern-slides, and bromide-enlargements of any of these can be obtained at a fixed tariff on application to the Director, Geological Survey, either at 33 George Square, Edinburgh, or at 28 J ermyn Street, London, S. \V. The subjects range from general landscapes illustrating the types of scenery characteristic of various geological formations, to near views exhibiting the details of rock structure. ~~mongst the photographs of special interest lllay be lllentioned those which illustrate the region of the great thrusts in the north-west of Scotland, the gabbro and granite areas of Skye, the granite area and the dykes of Arran, the pillow-Iavas of Knapdale and Ayrshire, the Carboniferous volcanic rocks of the Fife and Haddington coasts, the Lower Old Red Sandstone volcanic rocks of Glen Coe, and the glacial phenomena of various parts of Scotland. The negatives are of two sizes: whole-plate (8~ inches by 6t inches) and half-plate (6t inches by 4i inches). Prints from the original neg­ atives may be seen in the Offices of the Geological Survey, Edinburgh, or III the Library of the Geological Survey, London. The original negatives were taken by Mr. Lunn. A Catalogue of English and Welsh !Jhotographs has been issued. J. J. H. TEALL, Di1'eetor.
