^{page 44 note 1} For remarks on the difference between valley-glacier moraines in which polished and striated stones very seldom occur, and boulder-drifts in which the proportion of such stones, though very variable, is generally considerable, and often very great, see works and papers by Forbes and Lyell (Alps), Close (Ireland), and Jamieaon and Milne-Home (Scotland).

^{page 45 note 1} Professor Harkness, in the last number of the Quart. Journ. Geol. Soc, submerges the Lake District to a greater height than 700 feet above the level of Dunmail Raise, and brings np false-bedded marine drift to 1,100 feet above the present sea-level, or 100 feet higher than I have ventured to assert.
