South Lancashire and Cheshire . The occurrence of glacial striæ in the neighbourhood of Liverpool was first recorded by Mr. G. H. Morton, F.G.S., in 1859, though they had been previously noticed by Mr. J. Cunningham, F.G.S. In 1862 Mr. Morton described before this Society and the Liverpool Geological Society striæ on both sides of the river Mersey. Prof. Hull in 1864 § recorded the strim of Bidston Hill, pointed out to him by Mr. Cunningham, remarking that they point in the same direction as those of Liverpool. These had been previously noticed by Mr. Morton as having the precise direction N. 30° W. In consequence of his discovery of striee on both sides of, but at no great distance from, the Mersey, Mr. Morton in 1866∥ advocated the hypothesis of a glacier having descended the valley of the river; but in 1870 ¶ having discovered similar markings away from the river, adopted the theory of an ice-sheet having passed over this part of the country from S.E. to N.W. In the same year Dr. Ricketts, F.G.S., recorded striæ at Thatto Heath, and stated that the moving power which produced them had taken a course from south-east to north-west, the evidence of this being that grooves larger and deeper than others passed away from small indentations, which may have been the impressions of pebbles, in a north-west direction. In 1872 Mr. Mellard Reade, C.E., F.G.S., described cross striæ at Bootle, running E.N.E. and N. 22° W., and advocated the hypothesis of
