Extract

In May last I visited the Preston Hill Quarry, near Maidstone, in the company of the “Geological Field Class,” conducted by Professor Seeley, F.R.S., and took from it the specimen, the analysis of which is given below. In appearance the rock was a hard, grey, sandstone, containing fine quartz grains disseminated throughout its mass; its sp. gr. ═ 2.685; on the addition of an acid sulphuretted hydrogen was evolved, from the decomposition of calcium sulphide.
