With the model proposed in an earlier paper, the temperature variation of the ferromagnetism of nickel is discussed. By application of Fermi statistics to the electrons in the $d$ bands, the free energy is computed as a function of temperature and magnetic moment. At each temperature, the value of magnetic moment for…
X-ray (Hull-Debye-Scherrer) diffraction patterns were obtained for cobalt in a camera designed for high temperature work. No crystallographic change for this metal has been observed in the region about 850\ifmmode^\circ\else\textdegree\fi{}C at which the change in the photoelectric emission has been reported. The $\en…
Abstract The best method for obtaining the free energy of formation of rubber is by making use of the third law of thermodynamics. This makes necessary the determination of heat-capacity values of rubber from room temperature down to temperatures sufficiently low to apply an empirical formula for obtaining the values…
It is shown that the three-dimensional Patterson method can be so simplified by the use of the symmetry properties of the crystal under consideration that its use in determining the positions of atoms in crystals is practicable. This method is then used to determine the positions of the heavy atoms in proustite, Ag3As…
The double refraction of the chitinous hair of the crayfish is positive with respect to the axis of the hair, and is largely caused by the arrangement of submicroscopic, elongated chitin particles parallel to this axis (form birefringence). Using a series of relatively unreactive liquids and fluid mixtures which perme…
The present paper considers the possibility that screening by the atomic electrons has an appreciable effect on the energy distribution of $\ensuremath{\beta}$-particles emitted by heavy nuclei. A general formula is derived from which it is possible to conclude that the effect of screening is negligible. This result i…

A new value for the oxygen parameter in the structure of silver phosphate has been determined which gives the P–O separation in the phosphate group as 1.61A±0.03A. The value found here is slightly larger than that determined from an analysis of the crystal KH2PO4. The slight increase in P–O distance is explained on th…

Abstract Recently, Bragg and Williams have given an explanation of the variation of the degree of order in an alloy with temperature. According to this explanation it is essential to consider the ordering as a co-operative phenomenon characteristic for large assemblies of atoms. The force, V, tending to produce order,…

I. Introduction The study of the Calymenidæ was begun with the re-examination of the figured specimens and described types of the British species, and the results of this work have already been published (Shirley, 1931, 1933). An extensive series of British and foreign specimens has been examined. It is believed that…

Among the mechanical features the author discusses and compares the design and assembly of the principal parts of new- and old-type machines and gives the relation between printing speeds a…
