Mr. Miller’s new work, the “_Footprints of the Creator_,” of which we publish now another edition, authorized by the writer, is very appropriately dedicated to Sir Philip Grey Egerton, Bart., M. P. for Cheshire—a gentleman who possesses a magnificent collection of fossils, and whose skill and acquirements in this department of geology is known and appreciated both in Europe and America. The work itself is divided into fifteen chapters, in which the author treats of the fossil geology of the Orkneys, as exhibited in the vicinity of Stromness; of the development hypothesis, and its consequences; of the history and structure of that remarkable fish, the Asterolepis; of the fishes of the Upper and Lower Silurian rocks; of the progress of degradation, and its history; of the Lamarckian hypothesis of the origin of plants, and its consequences; of the Marine and Terrestrial floras; and of final causes, and their bearing on geological history. In the course of these chapters Mr. Miller discusses the development hypothesis, or the hypothesis of natural law, as maintained by Lamarck and by the author of the Vestiges of Creation, and has subjected it, in its geological aspect, to the most rigorous examination. Driven by the discoveries of Lord Rosse from the domains of astronomy, where it once seemed to hold a plausible position, it might have lingered with the appearance of life among the ambiguities of the Palæozoic formations; but Mr. Miller has, with an ingenuity and patience worthy of a better subject, stripped it even of its semblance of truth, and restored to the Creator, as Governor of the universe, that power and those functions which he was supposed to have resigned at its birth.
