A Week or two spent last month at Llandudno has given me the opportunity of examining the deposits on the Great Orme's Head, described by the Rev. T. G. Bonney in the August number of the Geological Magazine, and supposed by him to be the remains of a Kitchen Midden. The present communication is intended merely as a supplementary note to his paper. It appears that the beds, containing recent shells and bones, had been previously observed, and their true character ascertained, since the Rev. W. S. Symonds remarks, in some notes on the Geology of the district, “The beds of mussels and other shells on the Great Orme, which, at one time I imagined to have been elevated in raised beaches, Mr. Darbishire believes to be derived from old shell-heaps the accumulations of former inhabitants.”
