The Diatom Genus Tabellaria
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…
Some Effects of Treating Expansive Clays with Calcium Hydroxide
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,…

Neutron diffraction
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…

Preparation of Yttrium and Some Heavy Rare Earth Metals
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…

Electrodeposition of Tin-Nickel Alloy Plate from Chloride-Fluoride Electrolytes
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…
The Mechanism of Electropolishing of Copper in Phosphoric Acid Solutions
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…

Experimental Study of the Coercive Force of Fine Particles
The experiments described test the theory of fine-particle magnets. Particles of Fe, Co, and Ni, of size 100-2000A, were prepared by electrodeposition into a mercury cathode. Their sizes and shapes were determined with an electron microscope. Experiments on coercive force $\mathrm{vs}$ particle size show, in general a…

The Low Temperature Transformation in Ferrites
The general behavior of magnetite (iron ferrite) at its low temperature transformation ($\mathrm{ca}$ 118\ifmmode^\circ\else\textdegree\fi{}K) is reviewed. One of the properties which undergoes a large change is the magnetocrystalline anisotropy, which is larger in magnitude and has a lower symmetry below the transfor…
VI. A theoretical examination of the plastic deformation of crystals by glide
Summary Proofs are given of theorems stated in the Bishop-Hill theory of crystal distortion. Mathematical relations are established for the deformation of crystals by simultaneous shears, and the possibility of enforcing an arbitrary strain by glide is examined. The uniform stress states not exceeding the critical she…
