THE fundamental importance of the sun in the general economy of our world being finally established, our readers will not be surprised to hear that we assign that radiant and sublime abode to the human souls released from the earth, and successively purified and perfected by the long series of their multiplied incarnations in the bosom of the interplanetary spaces. Some philosophers have perceived this truth. The astronomer Bode placed the most elevated intelligences in the sun. "The happy creatures which inhabit this privileged abode," he says, "have no need of the alternate succession of day and night; a pure and unextinguishable light illumines it for ever. In the centre of the light of the sun, they enjoy perfect security, under the shelter of the wings of the Almighty."[6] Under what form may we picture to our fancy the inhabitants of the sun? We cannot answer this question without being acquainted with the _geography of the sun_, or as astronomers call it, his _physical constitution_, which differs essentially from that of the planets, of their satellites, and of the comets. He is unique in his position and office in the planetary system,--he must therefore be specially constituted. What is this special constitution? What is the geography of the sun? Would that it were in our power to reply to this question with precision; would that we could describe the configuration of the sun. Unhappily, science has not yet reached that point. The problem of the sun's true nature is full of uncertainty. Astronomers are divided between two opposite theories, and that which seems to be the best supported, is too recent to be set forth in a dogmatic fashion. We can only summarize the actual condition of our knowledge on this question, explain the theory which seems conformable to ascertained facts, and applying it to the subject on which we are engaged, endeavour to deduce the physical condition, which, in our opinion, would belong to the inhabitants of the king-star.
