Abstract
THE issue of the Revue scientifique for September 22 contains a notice of the death of Jules Violle, professor of physics at the Conservatoire des Arts et Metiers, which occurred at Fixin, near Dijon, on September 12. Violle was born in the same district on November 16, 1841. After obtaining his doctorate in 1870, he was in succession professor of physics at Grenoble, at Lyons, and at the Ecole Normale. In 1897 he was elected a member of the Paris Academy of Sciences in succession to Fizeau. He was president of the French Physical Society, of the Society of Electricians and of the Committee of Inventions for National Defence. His earliest research was a determination of the mechanical equivalent of heat by means of the Foucault currents in a disc rotating in a magnetic field. His result, about 4 per cent. too high, was published in 1870. His work on the temperature of the sun appeared in 1877, and in 1884 he proposed as a standard of light, that radiated normally by a sq. cm. of molten platinum at its freezing-point. From 1886 to 1905 he published in conjunction with Vautier a number of memoirs on the speed of sound particularly in tubes. His “Cours de physique,” which began to appear in 1883, was never completed.
