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…

The theory of the kinetics of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment. The density of germ nuclei diminishes through activation of some of them to b…
Abstract 1. Die Hydrosulfide und Hydroselenide von Natrium, Kalium, Rubidium und Cäsium wurden analysenrein dargestellt.
This paper represents the first step in an extended program whose aim is the investigation of solid solutions with special reference to the structures that may be formed by heat treatment and plastic deformation. It is hoped to include eventually observations in high fields (100,000 gauss) and at low temperatures. The…
The problem of the diffraction of x-rays by small crystalline particles is discussed by the methods of Fourier analysis, and the calculation of the intensity of the x-ray scattering from a single particle is reduced to the evaluation of a simple Fourier transform. This approach leads immediately to the interference fu…
Abstract The intensities of the rings formed when a beam of fast electrons is sent through a poly crystalline film were first studied by G. P. Thomson (1929) in the case of thin films of gold. The intensities were found to fit very well (Mott 1929) with those calculated theoretically on the assumption that the Laue th…

S ummary Various textile fabrics were exposed to a wide range of climatic conditions. Those exposed to waterlogged conditions were destroyed rapidly. In the case of cellulose fabrics this destruction was due solely to bacteria, and not to fungi or actinomycetes. In the case of wool, the evidence of microbiological act…
