It is suggested that sodium atoms in the high atmosphere may have a long, though intermittent, free life, despite frequent combination with oxygen atoms to form IVaO, through the reaction NaO + 0 = Na + 02. The source of energy of the light emitted by sodium at night is ascribed to the dissociation energy of oxygen. T…
An experiment has been designed to detect the contribution of intercrystalline thermal currents to the internal friction of polycrystalline metals. In accordance with a theory developed by one of the writers (C.Z.), the internal friction is a maximum when the vibration is partly isothermal and partly adiabatic with re…
A micro-electrophoretic technique was used to determine the characteristic pH-mobility curves for fibroin and for sericin and to ascertain the extent of removal of the latter during degumming by the soap and enzyme processes. The data suggest that sericin contains a much greater proportion of reactive groups than fibr…
ABSTRACT Explanations of origin are reviewed and environments in which black muds are in process of deposition are considered. The causes of blackness are examined and attention is given to diagenetic processes that take place in black muds. It is concluded that colors of black muds are due to several components, of w…

In the determination of the structure of a crystal with x-rays, it is essential that a reliable set of diffraction intensity data be obtained. During its passage through the crystal, the x-ray beam suffers a diminution in intensity due to absorption by the crystal itself, and the \nextent of this absorption will i…

Abstract The iron-nickel-aluminium ternary system has been brought into prominence in recent years on account of its application in the permanent magnet industry. A study of some magnetic properties of this system has been made by Köster (1932-3), but his work is largely concerned with features other than those dealt…
This paper deals with the variation of a-c conductivity with frequency and with that of apparent d-c conductivity with charging time for dielectrics exhibiting anomalous dispersion (i.e., having dielectric constants which decrease with increasing frequency). The a-c conductivity of a dielectric exhibiting simple anoma…
The self-diffusion of copper has been measured with a radioactive isotope prepared by neutron bombardment of zinc. The isotope is electroplated in a thin layer upon the surface of a copper disk. By measuring the decrease in $\ensuremath{\beta}$-ray emission from the sample due to the penetration of the radioactive cop…

Abstract (1) Maleic anhydride is known to react ( a ) with conjugated compounds, e.g. , butadiene, usually producing simple cyclic systems, and ( b ) with unsaturated olefinic substances like styrene and vinyl acetate, producing long-chain heteropolymers. It is now demonstrated that maleic anhydride, under the influen…

An edge correction is often required in determining the dielectric constant of an insulating material by the capacitance method. Theoretical formulas by which the edge correction may be computed have been considered for a number of electrode arrangements. Some of these apply to circular electrodes and some to rectangu…
