The paramagnetic susceptibilities of the salts of the rare earth elements Pr and Nd are considered on the assumption that it is permissible to represent the potential of the electric field of the atoms surrounding the metallic ion by a Taylor's expansion. This amounts to applying to the whole crystal the method of the…

The first part of this paper deals with a method for the accurate determination of the surface tension of liquids available in volumes of not more than one or two cubic millimetres. The method described does not involve any knowledge of the density of the liquid. The second part of the paper describes a series of meas…

The crystal lattice of germano sulphide, GeS, was examined by means of the Laue method, the powder method and the oscillating crystal method. The crystals are orthorhombic bipyramidal. The dimensions of the unit cell were found to be: $a=4.29\ifmmode\pm\else\textpm\fi{}0.01\mathrm{A}$, $b=10.42\ifmmode\pm\else\textpm\…
Abstract The investigation of the molecular structure of organic beryllium compounds is being studied by one of us (W. R. A.) from the standpoint of their infra-red absorption spectra. During a mechanical defect in the infra-red apparatus the diamagnetic susceptibilities of basic beryllium acetate, propionate, and piv…
Abstract It has long been known that certain crystal contacts will rectify alternating currents, but no entirely satisfactory theory has yet been given. The most generally accepted theory is that due to Schottky, which has recently been discussed by van Geel. If a metal, and a semi-conductor such as cuprous oxide or…

A treatment of the $N+1$ electron Schroedinger equation describing the elastic scattering of an electron beam by an atom with $N$ electrons in the outer shell which, in first approximation, leads to the equation $({\ensuremath{\nabla}}^{2}+{k}^{2}+U(r))f(x, y, z)=0,$ widely used for the computation of low velocity ela…

ABSTRACT By heating alkali silicates under CO 2 at high pressures, alkali carbonates are reformed to an extent depending upon temperature, pressure, and chemical affinity. The CO 2 thus existing homogeneously dissolved in the glass, and other anions and oxygen similarly dissolved and in chemical equilibrium are termed…
