The heat of the world.
--It is not sufficient that some eminent astronomer at Cambridge should discover a comet per month, but Professor Tyndall must state that the weight of this earth is such, and the velocity with which it moves so great, that if it should suddenly stop, the heat it would create would be sufficient to reduce it to a thin vapor. Professor Tyndall adds, that "if after the stoppage of its motion the earth should fall into the sun, as it assuredly would, the amount of heat generated by the blow would be equal to that developed by the combustion of five worlds of hold carbon."
