Plasmodia of Labyrinthula almost invariably appear in the diatom cultures and other small marine aquaria which I have kept during the last several years for a variety of purposes in Glasgow. These aquaria are stocked with material from Millport, I. of Cumbrae, and I think it quite certain that the Labyrinthula is impo…

Magnetic noise in synchronous machines is shown to be of two principal kinds. One is a vibration in the tooth frequency range which usually occurs whether load is present or not; the other has twice line frequency and is dependent on load current. The vibrating part of the structure is usually the stator but may be th…
Abstract Introduction.—For X-rays passing through matter, theory and experiment give a refractive index μ slightly less than unity, so that if a beam of X-rays falls on the plane surface of a solid at a small glancing angle less than the critical glancing angle, it is totally reflected. Determinations of the refractiv…
Summary Correlated data prove the approximate constancy of the number of oxygen atoms in the unit cells of several nepheline and elaeolite specimens. Thence the number of atoms of each kind per unit cell have been counted. The cell-volumes and optical properties have slso been correlated with the chemical composition.…
Article Geometrische Beziehungen unter den Strukturen der Modifikationen einer Substanz was published on September 1, 1931 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 77, issue 1-6).

The method for preparing an alkyl acetylene by the action of an alkyl halide on sodium dissolved in liquid ammonia was modified in certain details. Ethyl and methyl acetylene were prepared and purified and their melting and boiling points determined. Vapor pressures, densities and surface tensions were measured over a…
Abstract The object of this communication is to extend our knowledge of the relation between the interfacial tension of long chain carbon compounds dissolved in benzene and the hydrogen-ion concentration of the aqueous phase with which they may be placed in contact. To this extent, it forms an extension of earlier wor…
The structure of NaN${\mathrm{O}}_{2}$ was determined in order to test W. H. Zachariasen's prediction (J. Am. Chem. Soc. 53, 2123 (1931)) that the ${(\mathrm{N}{\mathrm{O}}_{2})}^{\ensuremath{-}}$ group would be angular with 120\ifmmode^\circ\else\textdegree\fi{} between the N\ensuremath{\bigominus}O bonds. Powdered c…
The magnetic susceptibility of alloys of copper and nickel in proportions ranging from 0.1 to 70 percent nickel have been studied. X-ray photographs of the alloys show that they are a homogeneous mixture of the copper and nickel crystals. Although copper is only weakly diamagnetic it requires 0.8 or 0.9 percent nickel…
Article Die elektrolytische Dissoziation von Säuren in Salzlösungen. I. Die Dissoziationakonstante der Essigsäure und die Aktivitäts Verhältnisse ihrer Ionen in den Lösungen einiger Alkali- und Erdalkalichloride. was published on August 1, 1931 in the journal Zeitschrift für Physikalische Chemie (volume 156A, issue 1).
Abstract In a recent paper Gerlach and Schneiderhan have described a series of experiments on the resistance of nickel considered both as a function of the temperature and as a function of an external field applied parallel to the wire. In the absence of an external field the change of resistance with temperature can…

IN the following I propose to give a general account of the present position of our knowledge as regards the algal ecology of static fresh-waters. A good deal of attention is now being paid to flowing waters in this country in relation to pollution and, since it became necessary to narrow down the field of these consi…

Two samples of a standard gelatin were studied, both prepared according to published specifications and washed free from diffusible electrolytes. The isoelectric point of this material was determined in four ways. 1. The pH values of solutions of gelatin in water approached the limit 4.86 +/- 0.01 as the concentration…
ABSTRACT Twenty‐one soda‐silica and twenty‐one soda‐lime‐silica glasses were made in platinum crucibles and the index of refraction and chemical compositioii of each glass were determined. From the data obtained equations were derived and a diagram was prepared showing the relations between index of refraction and com…
