Abstract
CONCERNING Mr. Schumann's comments (NATURE, January 24) upon Dr. Jeans's paper (December 6) on “The Ages and Masses of the Stars,” I should like to direct attention to the point of view expressed in my paper on “The Age of the Stars” which was read before the National Academy of Sciences on November 11 last, a few days before the meeting at which Dr. Jeans presented his work to the Royal Astronomical Society. It was there emphasised that the decrease of mass as a result of radiation is a necessary consequence of the theory of relativity. If relativity be accepted this must be so, independently of the mechanism involved in the change of mass as matter into mass as radiation. The fact that a star radiates means that it loses mass in this way: whether all the mass lost is lost by radiation is another matter. My paper, which is to appear in the Proceedings of the National Academy of Sciences for February, goes into the point more fully than I can here.
