Abstract
Atterton and Hoar's1 communication recalls two papers recently published on this subject. Schytil2 has shown that the surface-tension σ is related to the melting point Tm and the atomic volume V by where K1 is a constant. The other paper, due to Auerbach3, contains data to show that, for a considerable number of substances, including metals and even liquid helium, where ρ is the density of, and ν the velocity of sound in, the substance, K2 being another constant. As Schytil points out, expression (1) can be converted to one similar to that due to Wen Po4: where A is the atomic weight, νD the Debyo frequency, and K3 another constant.
