The minerals in the clay fractions of a black cotton soil and a red earth from Hyderabad, Deccan State, India
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 Refractive Index of Silicate Glasses as a Function of Composition*
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…
Micro-Diffusion Analysis and Volumetric Error.
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…
The Dielectric Properties of the Rutile Form of TiO2
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…
ATOMIC CONSIDERATION OF IMMISCIBILITY IN GLASS SYSTEMS*
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…
Properties of Rochelle Salt. III
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…

TheK-Absorption Edges andKβ2,5-Emission Lines of Two Zn-Ni Alloys
A double crystal spectrometer has been used to measure the shapes of the $K{\ensuremath{\beta}}_{2,5}$-emission lines and the $K$-absorption edges of zinc and nickel in two zinc-nickel alloys containing 17 percent zinc and 30 percent zinc by weight, respectively. These lines arise from transitions of valence and 3d el…

Melting and crystal structure
Abstract The role of various types of lattice flaws is discussed in their bearing on melting and crystal structure. Freezing-point determinations on lattices of a single molecule indicate the presence of such flaws in the crystals of polymethylene compounds. Freezing-point determinations on composite lattices of keton…
Temperature Dependence of Young's Modulus of Beta-Brass Single Crystals
Young's modulus of seven single crystals of beta-brass has been measured as a function of temperature from 25\ifmmode^\circ\else\textdegree\fi{}C to 505\ifmmode^\circ\else\textdegree\fi{}C for the purpose of studying the order-disorder phenomenon. The method used is that of the composite piezoelectric oscillator. The…
X. Finite complexes in crystals: a classification and review
Summary In crystals throughout which the interatomie binding is not uniformly of one type we may distinguish aggregates of atoms within which the binding is of one kind whereas that between one aggregate and the next is of a different nature. Such groups of atoms may be finite (molecules and complex ions) or they may…
