My friend and colleague, Mr. Goodchild, has contributed to the Geol. Mag. for July, August and October last, articles on Glacial Erosion in the Yorkshire Dale District, in order to evoke criticism; and as no one who knows the ground has come forward to reply in detail to his arguments, I am induced to offer some notes of my own on the subject.
page 97 note 1 The author wishes to state, that, when this article was written, the January Number had not appeared, and he was unaware of the fact that his colleague, MrMiller, Hugh, had written upon the subject (see Geol. Mag. 01, 1876, p. 23).CrossRefGoogle Scholar

page 103 note 1 It is possible that a scar of limestone or sandstone, however first originated, may in certain situations accumulate débris faster than subaerial agencies can remove it, and that old pre-glacial scars were uncovered by glacial erosion. On the other hand, as one of the results of the Glacial Period, we have, as seen in railway cuttings, old scars covered up by glacial drift, and being gradually uncovered by rain and rivers.
