The more a science is accurate, the more can accurate prophesies be drawn from it. Mathematics, to which alone appertains entire accuracy, communicate a portion of their precision to the sciences proceeding from them. Thus it is that accurate predictions are made by means of mathematical astronomy and chemistry. One is able to calculate eclipses millions of years ahead, without fear of one's calculations being found erroneous, as long as the sun, the moon, and the earth shall preserve the same relations as to bulk and distance. It is even permitted to us to foresee that these relations will be modified in a far distant future. Indeed, it is prophesied, on the strength of the
