Dr. Vaughan Cornish, who died in the spring of 1948, was perhaps best known for his writings on waves. This led him to the study of the phenomena of sand dunes and later to an investigation of snow waves and snow drifts, and finally to his valuable work Waves of Sand and Snow and the Eddies which make them (London, 1914).

Dr. Oscar Edward Meinzer, President of the American Geophysical Union, died suddenly in June 1948. Of his many important works perhaps that best known to glaciologists was his editorship of Physics of the Earth—IX. Hydrology (New York, 1942).

An appreciation of François E. Matthes, who died on 21 June 1948, and whose death was briefly announced in the last number of this Journal, will be found on p. 295 of the present issue.
