CONJECTURES RESPECTING THE SOURCE OF LIGHT.--Mr. J. Nasmyth concludes, from a series of observations of the spots on the sun and other solar phenomena, that, let the nature of light be what it may, its main source is derived from some action induced on the exterior surface of the sun, a notion shared by other physicists, who hold that the sun is not self-luminous but is surrounded by a light-emitting atmosphere.
