The following subjects were set at the Washington meeting in 1939 for papers to be read at Oslo in 1947 before the International Commission of Snow and Glaciers, one of the Commissions of the International Association of Hydrology. The Association is one of the component bodies of the Union.

• 1. The origin, drift and ablation of icebergs as aids in forecasting their seasonal appearance.

• 2. The physical changes in the snow conducive to run-off and particularly to flooding.

• 3. The study of the crystal structure of a glacier and its influence upon glacier movement.

Mr. G. Seligman, who has been appointed Chairman of the British Group of the Commission of Snow and Glaciers, will be glad to hear from any member who can make a contribution to these subjects by writing a paper or taking part in the discussions.

The following four special subjects have been assigned for action to temporary committees:

• (a) Standardization of maps of snow-cover and ice-cover for the world.

• (b) Uniform classification of different types of snow and snow-cover, and uniform nomenclature for the same.

• (c) A system of classification for the international bibliography of snow and ice.

• (d) Standardization of methods of snow-surveying and forecasting run-off from snow.
