Abstract
During last August the writers made a short stay in Switzerland and the Savoy, with a view to examine the structure of the ice of several of the larger glaciers. For this purpose a rough polariscope was used. It was so designed that a sheet of ice about two inches square, made very thin by cutting and melting, could be placed between the polarizer and analyzer. Notwithstanding that the thin slide so prepared, and held between glass plates, melted away rather rapidly, we succeeded in making a number of drawings of sections cut from the ice at different parts of the glacier, and at various angles with the line of motion. In some cases, however, where the structure was very fine-grained, the samples melted away before they could be sketched.
