Using the mass spectrometer as an analytical tool and as a means of rate measurement, the rates of helium diffusion through nine types of glass were measured. The temperature range covered was from –80° to 600°C. The highest rates were for fused silica and Vycor brand glass; the lowest were for the lead glasses. The r…

A simplified procedure is given for determining the 5 magnetostriction constants of a single crystal of a ferromagnetic cubic crystal. The crystal is cut as a disk parallel to a (110) plane, and strain gauges are cemented to the surfaces to measure strains in [001] and [$1\overline{1}1$] directions. A magnetic field s…
The thermal conductivity, electrical resistivity, and thermoelectric power have been measured in the temperature range from 20\ifmmode^\circ\else\textdegree\fi{}K to 300\ifmmode^\circ\else\textdegree\fi{}K for samples of artificial extruded graphite, natural molded graphite, and lampblack graphite. Experimental result…
Abstract A discussion is given of the advantages of the thermodynamic approach in the study of clay-ion-water systems. Generally valid equations for the description of the systems are given, and the relative significance of the osmotic terms is roughly assessed. The principal theoretical and experimental problem is th…
Abstract The clay minerals in a soil developed from Lenoir limestone (Ordovician) in Augusta County, Va., are kaolinite and chlorite. The Lenoir limestone contains clay partings consisting of hydrous mica, and the clay in the soil is considered to be residual from that in the parent limestone and modified by soil-form…

Abstract A series of clay minerals with a 7A series of reflections has been shown to exist in the MgO-Al 2 O 3 -SiO 2 -H 2 O system. It has been demonstrated both on synthetic and natural samples that these minerals are polymorphous with the 14A-series chlorite minerals. Widespread occurrence of these minerals in natu…

Experiments have been made with the marine diatom Nitzschia closterium grown in artificial light with different nitrogen sources. After the nitrogen source in the medium was exhausted, photosynthesis and cell division continued, the cells becoming nitrogen- and chlorophylldeficient. On adding a nitrogen source to defi…

The study of the dielectric, piezoelectric and elastic properties of KH2PO4 has been extended into the ferroelectric range of temperatures, and should permit further theoretical consideration of the behaviour of this group of crystals. In addition to the main transition, the treatment of which is still inadequate, the…
