V.—Mr. Harkee and Mr. Debley on the Scandinavian Ice-Sheet
Mr. Deeley tells your readers that he has recently been to the summit of Mont Blanc, and has been studying the difference between névé and glacier ice. This is interesting; but we thought that a great many people had done the same thing during the last hundred years, and we thought that one of them,...
