Abstract
II. IN the first series of notesl I stated how I was trying to find whether a combination of the meteoritic hypothesis and my system of chemical classification of stars into two series of ascending and descending temperatures might land us in a method of detecting physical differences. The importance of this inquiry depends upon the fact that any system of chemical classification along one line must land us in confusion, seeing that equal or nearly equal temperatures, and therefore chemistry—for chemistry is the child of temperature—mark two very different physical states in the life of a star in its progress from nebula to extinction as a cold solid globe.

The original temperature curve contained gaps below the cygnlan and above the Sirian types for two other possible classes, but these are omitted in the diagrams.
