Nickel‐tungsten alloys have been electrodeposited from the Watts type nickel plating bath which was modified by the addition of small amounts of sodium tungstate. Alloy composition and current efficiencies were studied at various cathode current densities, bath pH's and bath temperatures. Many of the cathode deposits…
The rate of mechanical deterioration of cellulose insulation is dependent on the conditions of its use. Those factors of major importance are the temperature applied and the presence of oxygen and moisture. Moisture even in small amounts greatly affects the mechanical stability of the cellulose insulation. In general,…
Abstract A new structure of carbon is proposed in order to account for the occurrence of extra lines on X-ray powder photographs of graphite. It has hexagonal layers similar to those of graphite, but arranged in a different sequence. About 14 % of the new structure is present in the samples examined.

Results are given which indicate that the ability of a textile fabric to withstand repeated flexing depends upon the struct ure of the fabric, the position and structure of the yarn in the fabric, and t h e kind of fib er from which the fabric is made.
For high accuracy in commercial refractometry, refractometers should be used more strictly as comparison instruments and series of standard samples with known refractivities over a range of room temperatures should be available for frequent check measurements. Tests for various mechanical and optical defects are neces…

It is shown that, for crystals of the cubic system, the reciprocal of the integral breadth of a Debye-Scherrer line is cos θ/λ times the volume average of the thickness of the crystal measured at right angles to the reflecting plane. The result is applied to calculate the integral breadths of reflexions from crystals…
Abstract The close-packed structures are made by piling up close-packed planes of atoms in three different relative positions. In proper hexagonal closepacking only two of the positions are used. The intensity of reflexion of X-rays is calculated for a structure which usually follows the hexagonal scheme, but has occa…
Abstract A new method for determining the surface tension of liquids has been derived. This involves the consideration of the advancing and receding contact angles of a liquid drop on a tilted solid surface. The theory has been tested by an improved optical projection technique for a variety of liquid/ solid systems a…
Abstract The need for a simple method of determining brittle points which would be adaptable to a large number of materials led the writers to develop the apparatus described below. There is presented here, for the first time, brittle point data on certain natural and synthetic rubber compositions. The study of the va…
During the last few years large collections of rock specimens from the Toro-Ankole volcanic fields, east and south-east of Ruwenzori, have been sent to Durham by the Geological Survey of Uganda for petrological investigation. The specimens recently studied include representatives of a suite of highly potassic ultrabas…
