THE younger generation of Cambridge physicists and many others will have noticed with regret the announcement in last week's NATURE of the death of Prof. P. V. Bevan at the early age of thirty-eight. He had a distinguished scientific record, and his friends confidently expected for him a useful and fruitful career. Entering Cambridge University in 1896 he took up the study of mathematics, and in 1899 was fourth Wrangler. The following year he was placed in the first division of the first class in part ii. of the mathematical tripos. With this equipment he turned his attention to experimental physics, and commenced research in the Cavendish Laboratory under Sir J. J. Thomson. In 1901 he was appointed to a demonstratorship, to which lecturing duties were added in 1904, and in 1908 he became Professor of Physics at the Royal Holloway College, a post which he held till his death.
