Tails of Comets, Solar Corona, and Aurora

UNDER this heading, in your issue of 5th inst., you report a paper by Prof. Osborne Reynolds, M.A., read at a meeting of the Manchester Literary and Philosophical Society, Nov. 29 last. This paper sets forth that the tails of comets, the solar corona, the aurora, and the Zodiacal lights are due to the ether which “fills” space. Comets' tails, as stated by the Professor, in his paper, are an effect due to the medium through which it passes being heated and illuminated by the comet; and that the other phenomena are also due to the ether.
