Tungsten-Molybdenum Equilibrium Diagram and System of Crystallization. The System Tungsten-Molybdenum. Discussion

J. W. RICHARDS, South Bethlehem, Pa.-I think that the diagrammatic results can be much more clearly set forth if they are plotted as follows: The present diagram, shown on page 1227 of Mr. Jeffries' paper, Logarithm of Per cent of Maximum Wattage Used plots the variation of wattage with temperature in a very inconvenient and uncertain-way. If, however, you plot as abscissas the logarithms of the wattage, you get very nearly a straight line, so that you can interpolate the values with much greater accuracy than you can by using
