ABSTRACT
The conception of the Sun’s constitution thus set forth, is like that of M. Faye in so far as the successive changes, the resulting structures, and the ultimate state, are concerned; but unlike it in so far as the Sun is supposed to have reached a later stage of concentration. Supposing the sun to have reached the state of a molten shell, inclosing a gaseous nucleus, it was concluded that the molten shell, ever radiating its heat, but ever acquiring fresh heat by further integration of the Sun’s mass, must be constantly kept up to that temperature at which its substance evaporates. Mr. Dawes has discovered that in the middle of the spot there is a blacker spot: just where there would exist a funnel-shaped prolongation of the cyclonic cloud down toward the Sun’s body, the darkness is greater than elsewhere.
