Seven of the better known specific-refraction ratios were examined for their comparative appl,icability to glass. It is shown by a comprehensive statistical treatment of available data (including many new data) that, of these ratios, only the Gladstone-Dale possesses to a satisfactory degree each of the following desi…

Abstract In considering existing information on the mechanical properties of raw rubber, it is not generally possible to distinguish between the effects of elastic and of plastic deformation. In the experiments described great care was taken to secure the complete removal of elastic strain, after stretching to various…
THE object of this study is the development of a quantitative theory of hysteresis-motor torque, especially in relation to magnetic properties and dimensions. The theory is interpreted physically in an idealized case, and applied to a particular motor to verify the result experimentally.

The magnetic susceptibility of the anhydrous chlorides of the iron group have been studied as a function of field strength up to 32,000 gauss and as a function of temperature down to 13.9\ifmmode^\circ\else\textdegree\fi{}K. Those compounds whose room temperature susceptibility characteristic indicates a positive Curi…

The mineral compositions of the clays from a red earth and a black cotton soil from Hyderabad, Deccan State, India, occurring in close proximity in the field are determined. Both soils are derived from the same or from very similar parent rocks, a coarsely crystalline granite or gneiss. For both soils there is practic…

The refraction per gram atom of oxygen, defined by a formula of either the Gladstone-Dale, the Newton, or the Lorentz-Lorenz type, equals the sum of terms characteristic of the component “metallic” elements, each of these terms being proportional to the number of atoms of that element per atom of oxygen. This is shown…
Ninety pages are devoted to the study of the error in volumetric titration, and can be of interest only to an occasional professional analyst. The apparatus, principles and practice of microdiffusion analysis are discussed for 186 pages; these will be of interest to the biochemist, but the methods will probably not su…
Three specimens of rutile were prepared and the dielectric properties studied over a range of frequency and temperature. A dielectric constant of approximately 100 was found which remained substantially constant through the highest radiofrequencies, falling off only in the infra-red region. The dielectric losses are l…
A bstract An attempt is made to apply the ideas of crystal chemistry to the problem of immiscibility in glass systems. Miscibility is favored by the tendency of the networkforming cations, Si, B, and P, to bond with all available oxygens in the melt. Immiscibility is favored in compositions which do not allow the othe…
The interaction theory of Rochelle salt is extended by supplementing the expression for the free energy of the deformed and polarized crystal by a term proportional to the fourth power of the polarization in the $a$ direction. This second approximation explains the dielectric and elastic saturation phenomena above the…
