Further researches on the temperature classification of stars. No. 2

In a previous paper discussing the photographs of stellar spectra taken with the calcite prismatic camera, I showed that the variation of the position of maximum intensity, when we dealt with the various genera of stars, corresponded with the temperature change—including in that term the possible results of electrical energy —suggested by the Chemical Classification. 2.Object of the Present Research . Obviously the next test to apply to the temperature curve based upon the Chemical Classification was to compare, under similar conditions, the relative temperatures of those genera placed on the same temperature horizon but on the opposite sides of the curve, since the chemical evidence indicated that, while there are differences in the conditions of absorption in such genera, their temperatures are approximately the same.
