Many persons knew that great blunders had been perpetrated, and it was notorious that even Mont Blanc itself was represented in a ludicrously incorrect manner on all sides excepting the north; but there was not, perhaps, a single individual who knew, at the time to which I refer, that errors of no less than 1000 feet had been committed in the determination of heights at each end of the chain; that some glaciers were represented of double their real dimensions; and that ridges and mountains were laid down which actually had no existence.
