Hours of Exercise in the Alps

Alpine climbing by the physicist who explained why the sky is blue - the Weisshorn, the Matterhorn attempts, and glacier work done with instruments between ascents. Tyndall climbed to measure things and stayed to climb. This edition is bound with a gallery of 60 plates of mountain painting, among them works by J. M. W. Turner, Caspar David Friedrich and Giovanni Segantini, and includes 7 restored and coloured illustrations.
