Constants in the Born and Mayer exponential expression for the repulsion between two ions have been recalculated. Using these, the lattice energies and equilibrium distances between ions have been recomputed, for alkali halide crystals. Expressions have been derived and tested for the calculation of the compressibilit…
Single crystals of ternary alloys of nickel, cobalt and iron with forty percent nickel or more have been examined, with a pendulum magnetometer, for ferromagnetic anisotropy. All alloys in this region have face-centered cubic structures, like that of nickel. A region of low anisotropy, for nearly equal cobalt and iron…
The equili-brium of the system Cobalt-Silicon is thoroughly investigated by means of thermal, microscopic, X-ray, dilatometric and magnetic analyses, and a new equilibrium diagram is proposed. In this system there exist four compounds, i.e., Co2Si(ε), CoSi(η), CoSi2 and Co3Si(γ); the first three melt without decomposi…
Twenty-one bands degraded to the red and associated with GeO have been observed in the region $\ensuremath{\lambda}2500$ to $\ensuremath{\lambda}2900$ The wave numbers of the band heads are expressed by the equation $\ensuremath{\nu}=37763.7+649.4 ({v}^{\ensuremath{'}}+\frac{1}{2})\ensuremath{-}3.81 {({v}^{\ensuremath…

A bstract Measurements have been made on “stabilized” glass fibers of five compositions in the system soda‐silica, at several temperatures in the annealing range, to obtain the viscosity, Young's modulus for instantaneous and total elasticity, and the. rate of delayed elastic distortion for each glass. Values for the…
Abstract The high boiling amines, obtained by the interaction of 1: 3‐dibromo‐propane and 1: 2‐diamino‐ethane hydrate, have been investigated. The lower terms contain straight chains of dimethylene and trimethylene groups separated by nitrogen atoms but in the higher boiling fractions cyclic amines are present.
A bstract Surface‐tension measurements were made on a series of molten glasses at 1200° and 1350°C, using the maximum bubble‐pressure method. A base glass was chosen with the composition of 17.4% Na 2 O, 10.1% CaO, 72.5% SiO 2 , or 1.4 Na 2 O: 0.9 CaO:6.0 SiO 2 , to which 0.030 gram‐atom of various elements in the for…
A new two-stage electron microscope has been designed and made for the express object of the microscopy of small objects by means of electron beams. The apparatus includes an optical microscope, and means are provided to bring any required object detail from the optical to the electron system. The focusing coils are m…

A bstract In this investigation there is carried out the carefully controlled heat treatment of a single crystalline glaze in which both the crystallizing and growth velocity were determined for the four types of crystal produced. It was found possible to produce crystals at any desired location by seeding; their size…
The effects of additional elements on the allotropic transformation point of cobalt can not be expected, as they are not attributed to a single factor. Although the simple conclusion from the results of this work can not be given, the following matters may be said to be cleared out. 1. Elements with body-centered cubi…

The magnetic and electric properties of the binary and ternary alloys involving iron, silicon and aluminium have been measured, and the relations of these properties to their respective concentrations have also been investigated. Those alloys containing 6_??_11 per cent of Si, 4_??_8 per cent of Al show specially exce…
