In an effort to clarify the confusion that has existed during past years regarding the flashover strength of insulators, the A.I.E.E. lightning and insulator subcommittee <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∗</sup> has been engaged, jointly with high voltage l…
X-ray diffraction patterns of vitreous Si${\mathrm{O}}_{2}$ and Ge${\mathrm{O}}_{2}$ have been made in an evacuated camera using Cu $K\ensuremath{\alpha}$ radiation monochromatized by crystal reflection. Intensity curves are obtained from the microphotometer records in the usual way. A method is developed for calculat…
The thirty modes of vibration of the regular plane hexagon model for the benzene molecule, including both the hydrogen and carbon atoms, are derived by the group theory method described by Wigner. From these the twenty frequencies of vibration are calculated in terms of a simple potential function involving six force…

Abstract Our knowledge of the compounds containing carbonyl and nitrosyl (NO) group attached to metallic atoms has been greatly extended in recent years, gely through the work of Hieber and Manchot and their collaborators; but structures which have been suggested, especially for the nitrosyl derivaties, are not in eve…

In an evacuated tube in which the slightest traces of organic vapors may occur, even with liquid air cooling, insulating layers are formed on surfaces subject to electron or canal-ray bombardment. These layers may be attributed to carbon compounds, and their formation is related to the polymerization of organic vapors…
Abstract Beginning in the year 1898 Heusler discovered as a series of ferromagnetic alloys, the most important containing copper, manganese, and aluminium. They are characterized by remarkable magnetic properties, because although composed only of paramagnetic or diamagnetic elements, they become ferro-magnetic after…
1. The rate of inactivation of crystalline trypsin solutions and the nature of the products formed during the inactivation at various pH at temperatures below 37 degrees C. have been studied. 2. The inactivation may be reversible or irreversible. Reversible inactivation is accompanied by the formation of reversibly de…

A study was made of organisms concerned with the red discoloration of salted hides, also termed "red heat", which defect may occasion loss in the leather industry through spotting and weakening of the fibre. Red halophilic sarcinae were isolated from Argentine hide. From Canadian hides showing red discoloration, two s…

Abstract This acid belongs to a large class of compounds known as the heteropolyacids, of which the structures and exact formulæ have long been a subject for speculation. The heteropolyacids are compounds in which one atom of such elements as P, Si, As, B, Al, etc., is combined with a number of atoms of an element suc…

Abstract A turning-point of the highest importance in the history of embryology was reached when in the spring of 1924 H. Spemann and H. Mangold obtained the first induction by the organizer of an amphibian egg. Th dorsal lip of the blastopore of an embryo of Triton cristatus was transplanted into the indifferent ecto…
