A determination of the magnetic saturation induction of iron at r00111 temperature has been made, using a modification of the Ewing isthmus method. Specimens were taken from several ingots of iron of exceptional purity prepared at th e National Bureau of Standards. Corrections were made for the effect of the small amo…
Abstract The crystal structure of the γ‐modification of sulphur trioxide has been completely determined. The cell is orthohombic, with cell constants a = 12.3 Å, b = 10.7 Å and c = 5.3 Å and contains 12 units of SO 3 ; the X‐ray density is 2.29. The structure is a molecule lattice built up of molecules S 3 O 9 ; a [00…

Abstract By polarimetric observations with regard to the effects of H3BO3, Na2B4O7 and KBO2 on various polyoxy compounds the following results and conclusion were obtained. Boric acid has a very feeble ability for complex formation with non-ionizable polyoxy compounds, such as mannit and glucose, while alkali borates…

A method is described for obtaining a quantitative measure of crystalline hydrocarbon present in stretched rubber samples by comparing the intensities of the diffraction spots and the amorphous halo appearing in the x-ray diagrams. This method has been applied in studying the crystallinity of stretched vulcanized rubb…

Potassium dihydrogen phosphate contains phosphate groups connected by hydrogen bonds. Different possible arrangements of the hydrogens result effectively in different orientations of the (H2PO4)— dipoles. Since these have the lowest energy when pointing along the axis of the crystal, there is a tendency toward spontan…
Abstract A survey has been made of the X-ray crystallography of some eighty sterol derivatives belonging mainly to the cholesterol and ergosterol series but including also calciferol and other photoderivatives of ergosterol and some higher plant and animal sterols. The measurements are recorded in four tables and incl…
Abstract Metal films of high and reproducible catalytic activity were obtained by condensation of their vapours on glass at any desired temperature. The catalytic activity was measured by the hydrogenation of ethylene. The crystal structure of these films was investigated by electron diffraction. By controlling the pr…
The method of complex eigenvalues is generalized to many dimensional problems by means of the scattering matrix. It is essential to allow for the existence of a background matrix on which the resonance is superposed. The "radioactive state" (i.e., the state with complex energy for which waves in all disintegration cha…

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…
