The relation between true and brightness temperatures of tantalum was determined by means of pyrometric observations on the inside and outside of a long thin-walled tube heated electrically. The brightness temperature as a function of heating current was determined by sighting on an electrically heated wire of known d…
This is the first of a series of research progress reports by Prof. E. R. Schwarz on the "Technical Evaluation of Textile Finishing Treatments" that is being sponsored jointly through a co-operative research agree— ment between Massachusetts Institute of Technology and the American Association of Textile Chemists and…
A brief historical review of the development of the electron supermicroscope is given. This is followed by a theoretical discussion of the resolving power attainable with the instrument and a summary of the important results which have been obtained by other workers. A description is given of the supermicroscope which…

Abstract The first careful examination of the red pigment occurring in the wing feathers of certain turacos, African birds belonging to the family Musophagidae, N. O. Scansores, was made by Church in 1869, and he it was who proposed the name "Turacin" for this pigment. His observations were extended in 1892, and since…

This article outlines the reasons cotton fabrics shrink, and gives many numerical examples. The length of cotton fibers change less than 1 percent from 45 percent relative humidity to wet, but diameter swells 14 percent. Unlike wool or rayon, contraction of cotton fibers does not contribute to shrinkage. Yarns of ordi…

From the equilibrium state of the whole system copper-nickel-silicon determined by the author, various sectional diagrams have been constructed. The following results are based on the experiments of the thermal and X-ray analyses as well as of the microscopic examination: Binary system as shown by M. G. Corson is not…

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 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…
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 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…
