4, 7, 10, 16, 28, 52, 100, 196: now the excesses of each of these numbers above the first are, 3, 3, 6, 12, 24, 48, 96: a series in which each term (after the first,) is double of the preceding one. Hence, the distances of the planets conform to a series following this law, (_Bode's law_, as it is termed.) And though the law is by no means exact, yet it was so far considered a probable expression of a general fact, that the deviation from this law, in the interval between Mars and Jupiter, was the principal cause which led first to the suspicion of a planet interposed in the seemingly vacant space; and thus led to the discovery of the planetoids, which really occupy that region. It is true, that the law is found not to hold, in the case of the newly-discovered planet Neptune; for his distance from the Sun, which according to this law, should be 388, is really only 300, 30 times the Earth's distance, instead of 39 times. Still, Bode's law has a comprehensive approximate reality in the Solar System, sufficient to make it a strong recommendation of any hypothesis of the origin of the system, that it shall account for this law. This, however, the nebular hypothesis does not. CHAPTER XI. THE ARGUMENT FROM DESIGN. 1. There is no more worthy or suitable employment of the human mind, than to trace the evidences of Design and Purpose in the Creator, which are visible in many parts of the Creation. The conviction thus obtained, that man was formed by the wisdom, and is governed by the providence, of an intelligent and benevolent Being, is the basis of Natural Religion, and thus, of all Religion. We trust that some new lights will be thrown upon the traces of Design which the Universe offers, even in the work now before the reader; and as our views, regarding the plan of such Design, are different, in some respects, and especially as relates to the Planets and Stars, from those which have of late been generally entertained, it will be proper to make some general remarks, mainly tending to show, that the argument remains undisturbed, though the physical theory is changed.
