] SPECTRUM ANALYSIS DISCOVERIES. 137 hours and a half, to a star of the fourth magnitude ; its light then again increases, and in a similar period of three hours and a half regains its original brilliancy. All these changes recur regularly in the space of less than three days, during which the star always remains visible to the naked eye. Whence comes this variation in the light of a star? Zoll- ner, with great acuteness, and supported by numerous obser- vations of these changes of brightness, ...offers a simple and unconstrained explanation, in supposing the cause to lie in the configuration and distribution of dark masses of scoriae, which form on the red-hot liquid body of the star in the process of cooling, and which, in consequence of the star's rotation on its axis, and the centrifugal force thus arising, would take certain definite courses on the surface of the star in a manner analogous to that which may be observed with floating icebergs on our earth. As a consequence of this peculiar relative motion, the dark masses of scorias would arrange themselves in a fixed order, and would produce on the surface of the star an unequal distribution of red- hot luminous matter, and accumulations of non-luminous scoriaB.
