The only point an reference to the first day which remains to be inquired into is the extent to which the work had proceeded at its close. As the commencement of the second day's work implies that at that time the earth had an independent existence, we may conclude that the first day's work comprehended the casting off of the several successive rings, and the condensation of those rings, or some of them, into the corresponding planets and satellites. These would probably still retain their intense heat, in virtue of which they would be luminous.

Many of the multiple stars may not improbably present to us much the same appearance as the solar system then presented. In many cases we have one large star, with one or more very minute attendants. Such a star is Orionis, a tolerably conspicuous star, which has two companions invisible to the naked eye, but visible with moderate telescopic power. (A telescope of 2.1 inches aperture, by Cooke, shows them well.) Five more companions are visible in a 4-inch telescope. In the large telescope at Harvard no less than 35 minute stars have been seen in apparent connexion with the brilliant star Vega. In all these cases it is true that the distances and periods of the companion stars are very much greater than in the case of the earth; but then our telescopes will only enable us to discern the more distant companions. Any small companion stars holding positions corresponding to those of the four interior planets, would be lost in the light of the primary star; and if, as is suspected, all the heavenly bodies are subject to some resistance, however small, from the medium in which they move, this resistance would in the course of ages diminish the mean distance, and with it the periodic time of the companion stars.

The latter part of the 5th verse has already been considered, and there is no need to recur to it at this point. At the close of the history we shall be in a better position to ascertain if any light has been thrown on that mysterious subject.

SECTION 5. THE SECOND DAY.

"And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.

"And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament, and it was so.

"And God called the firmament Heaven, and there was evening and there was morning, a second day"

The work of the second and third days evidently has its scene on the earth alone. At its commencement the earth appears to have become distinctly separated from the gradually condensing mass of the solar system, and to have assumed its spherical form. It had, in fact, acquired an independent existence; but it was still in a chaotic state. Its elements, which were hereafter to assume the three forms of solid, fluid, and gas, seem to have been still blended together. Of the three states, fluidity seems to have been that to which the mass most nearly approached. This seems to be indicated by the application of the term, waters, to the two parts into which it is now divided; for the Hebrew has no general word for "fluid," so that the only method of expressing it was by the use of this word "water" in an extended signification; and all scientific investigations point to the same conclusion. The heat, as yet, must have been so intense that no rocks or metals with which we are acquainted could have remained in a solid form. The sorting out and first arrangement of the materials of the earth, with probably the farther development of a large portion of them by the introduction of a new element, seems to have been the work of the second day.

When we proceed to examine the narrative more closely, two important questions suggest themselves:—l. What special interference of Creative Power does it indicate? 2. What is the meaning of the division between the waters which were above the firmament and the waters which were under the firmament?

1. What special interference of Creative Power took place on the second day? Till within the last ten years, it would have been difficult to give a satisfactory answer to this question; for if all the elements were already in existence at the commencement of the second day, their arrangement would, as it seems, have been brought about by the ordinary operation of natural laws which were already established. The cooling and condensation of a portion of the elements would have been effected by the radiation of their heat, and the portions thus condensed would, under the influence of gravitation, have arranged themselves in immediate proximity to the centre of gravity, forming a solid or fluid nucleus, round which those portions which still remained in a gaseous state would have formed an atmospheric envelope. But here again the spectroscope comes to our aid. In many of the nebulae which give in it the bright lines indicative of gas, hydrogen and nitrogen are the chief gases discovered. These must be in an incandescent state, or they would not be visible at all. But hydrogen cannot, in the present state of things, remain in this condition in contact with oxygen; it must instantly combine with it, that combination being attended with intense heat, and resulting in the production of water. The introduction of oxygen, then, must involve a very important crisis in the process of development; but that introduction must have preceded the formation of atmospheric air and water. Prior to the second day oxygen must either have been non-existent, or it must have existed in a form and under conditions very different from those under which it exists now. Free oxygen cannot be in existence in the sun or in any celestial object in which the spectroscope indicates the existence of incandescent hydrogen. The special act of the second day would appear to have consisted in the development of oxygen, or the calling it from a quiescent state into active operation.
