1883. Nature, 4 Jan., 235/2. Researches on the duration of solidification of surfused substances. Ibid. (1898), 27 Oct., 620/1. A very minute quantity of a solid will cause a mass of the same substance to pass from the surfused to the solid state. Ibid., 620/2. Surfusion, moreover, is not confined to pure metals, and he showed in 1893, that the eutectic alloy in the bismuth-copper series presents a marked case of surfusion.
