Abstract

IN NATURE, vol. xiii. p. 31, Dr. J. D. Hooker gives some notes of traces of ancient glaciers in Central, France, especially in the Mont Dore, and in a following short letter (p. 149 of the same volume), in reference to this notice of Dr. Hooker, the late Mr. G. Poulett Scrope, the celebrated describer of the volcanic regions of that country, calls in question the exactness of Dr. Hooker's observations. Dr. Hooker in a subsequent letter (p. 166) insists upon the correctness of his views, which he seems to believe original and never before advanced. Neither Dr. Hooker nor Mr. Poulett Scrope seem to have known that I have already, in a paper published in the Ausland (1872, Nos. 20 and 21, pp. 460 and 512) entitled, “Erosions und Gletscher wirkungen im Mont Dore, &c.” described the traces of glaciers to a still greater extent than even Dr. Hooker does. Not only did I name the place in question (which is situated just at the entry of the Gorge d'Enfer, upper valley of Mont Dore) and describe it as an ancient frontal moraine of a glacier, but I have also given the view of the late Prof. Lecoq (who was never an Abbé as Mr. Poulett Scrope seemed to believe), who says in reference to this locality, that if ever a glacier had existed in Mont Dore it must have been in this valley. But besides this point, which in itself is decisive, I noticed a great number of other localities affording examples of polished rocks, transported and rounded blocks, stone lines, and other evident traces of glaciers, which I will not re-enumerate, as they may be found in my above-mentioned paper.
