Lacto-Phenol Preparations
More or less permanent mounts of fungi, algae, root tips, epidermis, germinating spores, and other small objects may be made readily by transferring the material to Amann's lacto-phenol containing anilin blue, W. S. or acid fuchsin, used singly or mixed. The addition of 20 to 25% of glacial acetic acid to these mixtur…

II, THE CORRELATION OF PHYSICAL PROPERTIES WITH ATOMIC ARRANGEMENT
A bstract Physical properties of lead oxide‐silica glasses were studied in an attempt to correlate these properties and explain the anomalies occurring in their temperature and time curves on the basis of the structure of glass as derived in Part I of this investigation. The transformation point is denned as a critica…
Ueber die Dispersion von nativer und Hydrat‐Cellulose
Abstract Die Methode der Brechungsindex‐Messung mit Licht von veränderlicher Wellenlänge wird zur Untersuchung der Lichtbrechung und der Dispersion von Fasern herangezogen. Es zeigt sich, dass der Faser kein genau definiertes Brechungsvermögen zukommt, sondern dass dieses von den verwendeten Messflüssigkeiten abhängig…
The Structure of Ice II
The stability of the high pressure ice forms discovered by Tammann and Bridgman at very low temperatures and atmospheric pressure has made it possible to obtain x-ray powder diffraction photographs of these forms. The experimental procedure is very briefly discussed. An analysis of the ice II diffraction patterns lead…
THE CONSTITUTION OF LEAD OXIDE‐SILICA GLASSES: I, ATOMIC ARRANGEMENT*
A bstract A series of lead oxide‐silica glasses varying in composition from 10 to 60 mol % of PbO was prepared and diffraction patterns were obtained. The observed intensity curves derived from these patterns were matched with curves calculated from assumed structures by means of the scattering equation of Zernicke an…
The Preparation and Properties of So‐Called “Beta Alumina”
There is given a complete review of the literature concerning the supposedly “allotropic modification” of fused alumina known as “Beta”. The results of experiments with Bayer and “Dry Ore Process” alumina are quoted to show the definite relation which exists between the alkali content of the fusion and the amount of “…
Magnetic Measurements at Low Flux Densities Using the Alternating Current Bridge
A resumé is given of the basic relations between the magnetic characteristics of the core of a coil and the inductance and resistance of the coil as measured on an alternating current bridge. Modifications of the simple relations to take account of the interactions of eddy currents and hysteresis in the core material…
X-ray spectrography of polymers and in particular those having a rubber-like extensibility
X-RAY SPECTROGRAPHY OF POLYMERS AND X-RAY SPECTROGRAPHY OF POLYMERS AND IN PARTICULAR THOSE HAVING A RUBBER- BY J. R. KATZ. Received I 3th August, 1935. 1. Introduction. For many years H. Staudinger defended the theory that polymers have-in the simplest case-a long chain form of molecules in which a certain

Sur l'élasticité de la cellulose. (Sur la constitution de la partie cristallisée de la cellulose IV)
Abstract 1. Le module d'élesticité de la cellulose et de quelques‐uns de ses dérivés a été étudié en fonction de l'humidité, de la température, de l'orientation et de la tension à laquelle l'objet a été soumis. Les mesures ont é effectuées à l'aide de la méthode statique et surtout à l'aide de la méthode acoustique.

Abstract Die Theorie von DK. und Lfk. der Mischkörper aus isotropen (amorphen oder regulären) Substanzen 5 ) wird hier ausgedehnt auf die nichtregulären Systeme, wo schon der Vielkristall einer einzigen reinen Substanz den Charakter eines Mischkörpers aufweist. Die Genauigkeit der alten Formeln von Voigt und Andrade‐C…

FOURIER ANALYSIS OF X‐RAY PATTERNS OF VITREOUS SiO 2 AND B 2 O 2 *
A bstract The X‐ray scattering curves for vitreous SiO 2 and B 2 O 2 are obtained in a vacuum camera, using monochromatic Mo and Cu radiation. A Fourier analysis of the scattering curve gives directly a curve representing the distribution of neighboring atoms about any one atom. For SiO 2 , the distribution curve esta…
The Copper Oxide Rectifier
The equilibrium diagram of the copper: copper oxide: oxygen system controls the conditions of formation of the cuprous oxide rectifier. The interface between the cuprous oxide and the copper from which it is formed can be studied with polarized light. Intimate contact exists for more than half the total area. The tech…
