ABSTRACT Although the morphology of the radulae of molluscs have been extensively studied, but little is known of their composition ; it is generally stated to be of a chitinous nature. There are two exceptions to this statement: Troschel (1856) and Sollas (1907). The former reported that calcium, phosphorus and iron…

The equations of the individual processes of self nucleation are utilized through an electrical analogy to obtain the nucleation frequency. This process is shown to be shorter and less subject to error than that of previous investigators since the appearance of indeterminant integration constants is completely avoided…
Abstract Es werden verschiedene physikalische Konstanten heterogener Körper aus den Konstanten ihrer homogenen Bestandteile nach einer einheitlichen Methode berechnet. In dieser ersten Arbeit wird die Berechnung der Dielektrizitätskonstanten und der Leitfähigkeiten für Elektrizität und Wärme der Mischkörper aus isotro…
ABSTRACT In normal glassmaking processes not one of the alkaline carbonates is decomposed by heat alone, whereas at 800°C their reaction with silica proceeds rapidly. Calcium carbonate, on the other hand, decomposes completely at 610°C; hence it is almost entirely thermal and does not rise by interaction with silica.…
The chemical properties of sericin are reviewed. When alkalies or soap react upon sericin a progressive degradation of the sericin particle takes place in solution after the sericin leaves the silk. The grams of sericin combining with one gram equivalent of soap or alkali when a point of equivalence is attained in sol…
ABSTRACT Cylindrical test pieces, rammed under a pressure of 10,000 pounds per square inch, were heated to temperatures varying between 1300°C and 1500°C. The rate of inversion of quartz to cristobalite and the rate of spinel formation in mixtures of electrically fused magnesia and alumina were determined from the slo…

ABSTRACT A method has been developed for analyzing the X‐ray diffraction patterns of amorphous solids, and the atomic arrangement in two simple glasses has been completely worked out. In SO 2 , for example, each silicon is tetra‐hedrally surrounded by 4 oxygens at a distance 1.60 AIR, and each oxygen is shared between…
Abstract The subject of joint-formation, about which there has been much speculation and conflicting hypothesis, involves two main problems: (1) He question whether the characteristic shape of the articular surfaces is due to extrinsic or intrinsic factors. (2)The question how two opposing bone rudiments developing fr…
The thermal and electrical conductivities of two specimens of Bi single crystals were determined as a function of temperature and orientation of magnetic field relative to their crystallographic axes. These effects were observed at temperatures ranging from -170\ifmmode^\circ\else\textdegree\fi{}C to -50\ifmmode^\circ…

Abstract Hitherto it has generally been assumed that the catalytic hydrogenation of ethylene linkages in organic compounds at surfaces such as nickel or platinum involves merely the direct addition of a molecule of hydrogen across the double bond. In view of the fact that chemi-adsorbed hydrogen on catalytically activ…
