This slab was found lying on the sand about 150 yards within high-water mark, a little northward of the projecting headland called Whitberry Point, on the coast of East Lothian. The head-land is of trap, which rests on a red sandstone, similar to that of the slab. The sandstone covers some acres northward of the headland at low water, running out in a succession of ridges in a north-east direction, and dipping to the south-east. The slab is of a triangular form; its length is 17 inches, greatest breadth 9, and the thickness varies from 1½ to 2 inches.
