Crystallization of Rochelle salt from heavy water raises the upper Curie point of the material by 11\ifmmode^\circ\else\textdegree\fi{}C and lowers the lower point by 5\ifmmode^\circ\else\textdegree\fi{}C, but leaves the other properties substantially unchanged.

The Fourier transform of a crystal is a representation which, if fully known, would be equivalent to, and give the same information as, the usual description of a crystal. At the same time the Fourier transform is very closely related to the diffraction properties and it offers the best survey of the diffraction data…
X-ray diffraction patterns of plastic sulphur at room temperature and of liquid sulphur at several temperatures ranging from 124°C to 340°C have been obtained. The position of the main peak in terms of (sin θ)/λ is 0.140 at 124°C, 0.138 at 147°C, 0.138 at 151°C, 0.139 at 157°C, 0.127 at 166°C, 0.127 at 175°C, 0.125 at…
THE PROBLEM OF STRESSES IN CONCRETE RUNWAYS OF AIRPORTS IS ESSENTIALLY THE SAME AS THE PROBLEM OF STRESSES IN CONCRETE PAVEMENTS OF HIGHWAYS, EXCEPT THAT BOTH THE WHEEL LOADS THAT MUST BE CONTEMPLATED AND THE AREAS OF CONTRACT BETWEEN TIRE AND CONCRETE ARE GREATER FOR RUNWAYS THAN FOR HIGHWAYS. THESE DIFFERENCES, ESPE…

An estimate is given of the way in which the strain energy associated with a particle of precipitate depends upon the shape of the particle. It is shown that the energy can only be reduced if the precipitate forms in flat plates, and then only in the case of particles which have broken away from the lattice of the mat…
The various causes of internal friction in solids are discussed. Internal friction depends in general on thermal currents which occur owing both to the inhomogeneous strains set up by the vibrations in the solid, and to the variations in the elastic constants from point to point in polycrystalline materials. The influ…
A theoretical treatment of multiple Rutherford scattering is given which is exact if one considers electrons with the same total path length in the scatterer. The approximations necessary for the actual solution of the problem for a thin scatterer can be shown to have little effect on the results for small angle scatt…
The ferromagnetic anisotropy constant ${K}_{1}$ has been accurately measured by the magnetic torque method for a group of iron alloys containing up to 13.7 atomic percent silicon. The points fall on two intersecting straight lines given by the equations: ${{K}_{1}\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5…
It has long been the opinion of many textile technolo gists that some precise and easily duplicated means of determining the index of refraction would be of paramount value in investigating the structure of textile fibres as well as assisting in their positive identification. Such other phenomena as the effect of mois…

A bstract A careful study of the viscosities of glasses composed of silica and between 22 and 40% soda shows that viscosity‐composition isotherms are smooth curves. The sharp minima at about 34% Na 2 O (and possibly at about 26% Na 2 O) observed by Preston 1 are found to be entirely absent. Neither time nor shearing s…
A bstract An apparatus is described for studying clay minerals by the differential thermal method, which has some advantages over previous types of apparatus. Thermal curves are given for many of the pure clay minerals for use as standards of identification. The use of this method quantitatively for the determination…
