For if, in its perihelion, it should approach within a certain degree of the sun (as by their calculations they have reason to dread) it will receive a degree of heat ten thousand times more intense than that of red hot glowing iron, and in its absence from the sun, carry a blazing tail ten hundred thousand and fourteen miles long, through which, if the earth should pass at the distance of one hundred thousand miles from the nucleus, or main body of the comet, it must in its passage be set on fire, and reduced to ashes: that the sun, daily spending its rays without any nutriment to supply them, will at last be wholly consumed and annihilated; which must be attended with the destruction of this earth, and of all the planets that receive their light from it.
