Evidences of Ancient Glaciers in Central France

WERE this a question concerning volcanic phenomena, with which Mr. Scrope is as familiar as I am with glacial ones, I might be disposed to defer to his opinion. As it is, having only his assertion that I have mistaken the results of a recent landslip (i.e. a spot where there are no traces of landslip, and to which no landslip could have reached) for time-worn and weathered glacier-transported blocks, I ask the readers of NATURE to pause before disposing of my powers of observation as summarily as Mr. Scrope does; remembering that the history of all glacial phenomena, from scratched boulders to lake-basins, has been successively overlooked, denied, and misinterpreted, before being understood and accepted.
