This fact alone is suspicious; the more so, because there is absolutely nothing in the context to indicate that anything but an ordinary day is intended. Not only so, but there _is_ in the context something that does very clearly indicate (and I think Dr. Réville is perfectly justified in insisting on this) that an ordinary terrestrial day is meant. One of the primeval institutions of Divine Providence for men, my readers will not need to be reminded, was that of a "Sabbath," which any one reading the text would understand to mean a day, and which the Jews--the earliest formal or legal recognizers of it--_did_ so understand, and that under direct Divine sanction. If the _days_ of Genesis mean indefinite periods of aeonian duration, how is the seventh _day_ of rest to be understood? But even if these difficulties are overcome, absolutely nothing is gained by taking the day to be a period. I presume that the object of gaining long periods of time instead of days in reading the Mosaic record, is to assume that the narrative means to describe the actual production on the earth of all that was created; in other words, to assume a particular meaning for the words "created," "brought forth," &c and then to make out that if a whole age is granted, Science will allow us a sequence of a "plant age" a "fish and saurian age," a "bird age," and a "mammalian age";--that is, in general terms and neglecting minor forms of life. But then _to make any sense at all with the verses_ we are bound to show that each age preceded the next--that one was more than partly, if not quite completely, established _before_ any appearance of the next. It is to this interpretation that Professor Huxley alludes when he says, in his first article,[1] "There must be some position from which the reconcilers of Science and Genesis will not retreat--some central idea the maintenance of which is vital, and its refutation fatal.... It is that the animal species which compose the water population, the air population, and the land population,[2] respectively, originated during three successive periods of time, and only during those periods of time." [Footnote 1: "Nineteenth Century," December, 1885, pp. 856-7.] [Footnote 2: These (unfortunate) terms are Mr. Gladstone's.] For my own part, I hasten to say that, as one of the despised race of "reconcilers," not only is this idea no central position from which I will not retreat, but one which I should never think of occupying for one moment. But on the view of the _periods_, some such position must be taken up. And if so, I must maintain that Professor Huxley has shown--if indeed it was not obvious already--that the idea of a series of periods, and in each of which a certain kind of life began and culminated (if it was not fully completed) _before_ another began, is untrue to nature. This, therefore, cannot have been intended by the author of Genesis.
