Waves of ice on the Gorner Glacier (Switzerland) are described. These finally assume an appearance very similar to the ice pyramids of the Himalaya. The author shows that the former originate as avalanche snow which remains above the general surface of the glacier through its lightness and greater resistance to ablation than the denser glacier ice, and suggests, as do Visser and others, that some Himalayan ice pyramids also originate as avalanche snow.

Shortly before the war this new word for the study of glaciology was coined in Central Europe. The Greek noun κρύος means “cold.” It is not clear why this word should be applied exclusively to cooled water; it could equally well be used for any cooled substance, for example carbon dioxide or ice cream.

Most astronomical hypotheses on the causes of ice ages are dynamically untenable. Alterations in the amount of solar radiation, however, have long been recognized as a possible cause, but only with recent progress in the theory of stellar evolution has it become clear that such changes must occur. At irregular intervals the sun will pass, and will have passed, with low relative speeds through interstellar hydrogen clouds, and the gravitational action of the sun leads to an increase in the quantity of material falling to the surface with high velocity. The conversion of the kinetic energy of fall of this material results in an increase of emission at the solar surface. Increases of order up to about 10 per cent of the present total radiation could occur, and the process is such that the extra energy would be located mainly in the shorter wavelengths.
