Excerpt from The Edinburgh New Philosophical Journal, Vol. 51: Exhibiting a View of the Progressive Discoveries and Improvements in the Sciences and the Arts The Theory of Successive Development in the Scale of being both Animal and Vegetable, from the earliest periods to our own time, as deduced from Paloeontological evidence. The theory of successive geological development, so generally adopted by geologists, is clearly stated by Professor Sedgwick in his admirable Discourse on the Studies of Cambridge. "There are traces, " he says, "among the old deposits of the earth of an organic progression among the successive forms of life. They are to be seen in the absence of mammalia in the older, and their very rare appearance in the newer secondary groups, in the diffusion of warm-blooded quadrupeds (frequently of unknown genera) in the older tertiary system, and in their great abundance (and frequently of known genera) in the upper portions of the same series, and lastly, in the recent appearance of man on the surface of the earth." (p. xliv.) "This historical development, " continues the same author, "of the forms and functions of organic life during successive epochs seems to mark a gradual evolution of creative power, manifested by a gradual ascent towards a higher type of being." - Ibid. p. cliv.
