The same eternal separation of all the forms of being and the same eternal approximations, however varied the manifestations may be at different periods, remain unaltered and unalterable. Linnæus ventured to place “man” in the category or class mammalia, while at the same time he separated the mammalia from birds and other forms of being—thus assuming that the human creation had a closer union with pigs and dogs, than the latter have with birds, etc. At this every Christian and believer in a future state of being must revolt, for though there are certain approximations that cannot be disregarded, nevertheless it is absolutely certain that the human creation is separated by an interval wider than that separating any of the forms of mere animal life, and therefore his classification must be wrong. It is not intended to make this a scientific work, but on the contrary, to popularize for the general reading of the people, some few elementary truths of zoology and physiology in order that they can better comprehend the subject really to be discussed, viz.:—the specific differences and specific relations of the white and black races. But the author feels himself conscientiously impelled to dissent from the classifications of Linnæus, and those modern naturalists who follow him, not only as being untrue in point of fact, but pregnant with mighty mischief. Linnæus placed “man” in the category mammalia, but made him an order, a genus and species by himself. This is false as a matter of fact, for in the entire world of animal existence there is no such fact as a single species. All the forms of life are made up of groups or families, properly genera, and each of these is composed of a certain number of species. These species, as already observed, differ from each other. They begin with the lowest, or simplest, or grossest formation, and rise, one above the other, in the scale of being, until the group is completed; so that they are all, not only specifically different from each other, but absolutely unlike each other in every thing, in the minutest particle of elementary matter as well as in those things palpable to the sense. Generally considered, they resemble each other, but specifically considered, they are absolutely distinct, and, it need not be repeated, the distinctions in each case or each individual species are also specific.
