Experimental observations are reported on the magnetic properties of thin evaporated films of nickel. The saturation magnetization follows the general prediction of Klein and Smith after somewhat arbitrary modifications on the basis of fitting the Weiss curve for bulk specimens, as suggested by Drigo. Qualitatively ob…
This paper is intended to supplement the review articles published by Stoner in 1948 and 1951, firstly by considering in greater detail the quantum-mechanical and statistical-mechanical foundations of the collective electron theory and secondly by considering briefly a wider range of relevant experimental results.In S…

Plankton samples of Tabellaria from all the lakes of the English Lake District have been examined and evidence of morphologically distinct populations has been found in samples from (a) a single lake at one time, (b) different lakes, and (c) a single lake at different times. Clone cultures have been used to study the…
The addition of calcium hydroxide to expansive clays results in beneficial reductions in the swelling characteristics and in increased resistance of the material to deformation under load. In this study, improvements in clay properties corresponded generally to the amount of calcium hydroxide addition. For two clays,…

A description is given of the progress over the past few years of neutron diffraction, with particular reference to its applications, often alongside complementary x-ray studies, to investigations in structural crystallography and the physics of the solid state. This outlines the relevant principles of neutron scatter…

A method was devised for preparing massive metallic yttrium, terbium, dysprosium, holmium, erbium, and thulium in high purity and high yields by reducing the rare earth chloride or fluoride with calcium metal in tantalum containers in an inert atmosphere. Ytterbium fluoride could be reduced only to the divalent state…

Tin and nickel can be codeposited in approximately equi‐atomic proportions from solutions containing stannous chloride, nickel chloride, and fluorides. The alloy deposits thus obtained are almost fully bright and are single phase, having a nickel arsenide type of structure. Below 300°C the deposits are quite stable, b…
Experiments with a composite anode having projections and recesses on its surface insulated from each other showed that the current distribution between projections and recesses underwent very little change when the total current fell and polishing conditions were established. This called for a radical revision of pre…

A DESCRIPTION IS GIVEN OF THE APPARATUS FOR MAKING HIGH-PRECISION MEASUREMENTS OF THE VELOCITY OF AN ULTRASONIC PULSE IN CONCRETE. THE USE OF THIS VELOCITY (THE LONGITUDINAL-WAVE VELOCITY) AS A CRITERION OF QUALITY IS DISCUSSED WITH REFERENCE TO SUCH CONVENTIONAL CRITERIA AS THE MODULUS OF RUPTURE, COMPRESSIVE STRENGT…
