It may be worth while to record the occurrence of phosphatised carbonate of lime in Cave Ha, near Giggleswick, which has been explored by Prof. Hughes (see Journal of the Anthropological Institute for December, 1873, vol. iii.). The phosphatised material, which forms stalagmitic layers at the side of and interstratified with the other deposits, is leaden-grey in colour, weathering light brown outside, friable, and full of small holes. Portions of it yielded, on analysis, a large per-centage of phosphate of lime.
