The Formation of Hydrogen Peroxide during Corrosion Reactions
Hydrogen peroxide was shown to be formed during the corrosion of aluminum and other metals in the presence of an excess of oxygen. The Russell effect of metals was found to be caused by the production of hydrogen peroxide and to provide a highly sensitive test for the formation of hydrogen peroxide at metal surfaces.…

The Quadratic Zeeman Effect
The Zeeman effects of the principal series lines of sodium and potassium in the range $n=10 \mathrm{to} 35$ are observed in absorption, using the new 60-inch cyclotron magnet. With a field of 27,000 gauss, the lines having $n$ in the neighborhood of ten show a normal triplet representing the complete Paschen-Back effe…
Electrostatic Electron-Optics
Certain types of electrostatic fields may be used as lenses to focus electron beams. The theory of these lenses is developed for electric fields that are symmetrical about a central axis. The introduction of two velocity functions exactly reduces the partial differential equations of electron motion to a series of ord…
The thermal and electrical conductivities of carbon and graphite to high temperatures
The thermal conductivity K is derived in terms of the difference in temperature which, in the steady state, is set up between the axis and the surface of a rod or tube of the material when the latter is electrically heated in an evacuated enclosure. The electrical conductivity σ is derived in the course of the same ex…

Further Tests of the Validity of X-Ray Crystal Methods of Determininge
The authors have continued their efforts to absolve the x-ray method of determining the electronic charge of the criticism that Bragg reflection determines the lattice dimensions in only a very shallow surface region whereas the density determinations have been made on a much larger volume of crystal. In earlier work…
The Mechanism of the Negative Point to Plane Corona Near Onset
Oscillographic studies have been made of the currents in negative point to plane coronas in air. The oscillograms obtained indicate that the negative corona current is composed of discrete pulses whose magnitude and frequency have a definite relationship to the corona current, point size and gas pressure. The frequenc…
On certain simple peptides occurring in marine algae
described the isolation of water-soluble peptides from the brown alga Pelvetia canaliculata forma libera S. M. Baker and the red alga Corallina officinalis Lirn. It was then suggested that the presence of peptides in algae was due to a lack of metabolic balance determined either by desiccation or by low illumination.…
The Focusing of Charged Particles by a Spherical Condenser
The paths of charged particles traversing a portion of an ideal spherical condenser are worked out. The section of the condenser considered is bounded by two rays, enclosing an angle $\ensuremath{\Phi}$, from the common center of curvature, $O$, of the equipotential surfaces. It is shown that a group of particles, hom…

X-Ray Analysis of the Structure of Water
X-ray diffraction patterns of water were obtained at five temperatures: 1.5°, 13°, 30°, 62°, and 83°C. The radiation was Cu Kα and Mo Kα, monochromated by reflection from a rocksalt crystal. Radial distribution curves for water at the five temperatures were obtained by a Fourier analysis of the x-ray intensity curves.…
The problem of the carbonate apatites; a carbonate oxy-apatite (dahllite)
Crystal structure analysis shows there can be no further doubt regarding the existence of the carbonate apatite or oxy-apatite molecules. Chemical analysis is given of the dahllite from Mouillac, France, upon which x-ray measurements were made.
