He then takes the quadrumana, and places it in the following arrangement:—
| Typical | Simiadæ | (Monkeys of Old World.) |
| Sub-typical | Cebidæ | (Monkeys of New World.) |
| Natatorial | Unknown | |
| Suctorial | Vespertilionidæ | (Bats.) |
| Rasorial | Lemuridæ | (Lemurs.) |
He considers the simiadæ as a complete circle, and argues thence that there is no room in the range of the animal kingdom for man. Man, he says, is not a constituent part of any circle, for, if he were, there ought to be other animals on each hand having affinity to him, whereas there are none, the resemblance of the orangs being one of mere analogy. Mr. Swainson therefore considers our race as standing apart, and forming a link between the unintelligent order of beings and the angels! And this in spite of the glaring fact that, in our teeth, hands, and other features grounded on by naturalists as characteristic, we do not differ more from the simiadæ than the bats do from the lemurs—in spite also of that resemblance of analogy to the orangs which he himself admits, and which, at the least, must be held to imply a certain relation. He also overlooks that, though there may be no room for man in the circle of the simiadæ, (this, indeed, is quite true,) there may be in the order, where he actually leaves a place entirely blank, or only to be filled up, as he suggests, by mermen! [266] Another argument in his arrangement is, that it leaves the grades of classification very much abridged, there being at the most seven instead of nine. But serious argument on a theory so preposterous may be considered as nearly thrown away. I shall therefore at once proceed to suggest a new arrangement of this portion of the animal kingdom, in which man is allowed the place to which he is zoologically entitled.
I propose that the typical order of the mammalia should be designated cheirotheria, from the sole character which is universal amongst them, their possessing hands, and with a regard to that pre-eminent qualification for grasping which has been ascribed to them—an analogy to the perching habit of the typical order of birds, which is worthy of particular notice. The tribes of the cheirotheria I arrange as follows:—
| Typical | Bimana. |
| Sub-typical | Simiadæ. |
| Natatorial | Vespertilionidæ. |
| Suctorial | Lemuridæ. |
| Rasorial | Cebidæ. |
Here man is put into the typical place, as the genuine head, not only of this order, but of the whole animal world. The double affinity which is requisite is obtained, for here he has the simiadæ on one hand, and the cebidæ on the other. The five tribes of the order are completed, the vespertilionidæ being shifted (provisionally) into the natatorial place, for which their appropriateness is so far evidenced by the aquatic habits of several of the tribe, and the lemuridæ into the suctorial, to which their length of muzzle and remarkable saltatory power are highly suitable. At the same time, the simiadæ are degraded from the typical place, to which they have no sort of pretension, and placed where their mean and mischievous character seem to require; the cebidæ again being assigned that situation which their comparatively inoffensive dispositions, their arboreal habits, and their extraordinary development of the tail, (which with them is like a fifth hand,) render so proper.
The zoological status thus assigned to the human race is precisely what might be expected. In order to understand its full value, it is necessary to observe how the various type peculiarities operate in fixing the character of the animals ranked in them. It is easy to conceive that they must be, in some instances, much mixed up with each other, and consequently obscured. If an animal, for example, is the suctorial member of a circle of species, forming the natatorial type of genera, forming a family or sub-family which in its turn is rasorial, its qualities must evidently be greatly mingled and ill to define. But, on the other hand, if we take the rapacious or sub-typical group of birds, and look in it for the tribe which is again the rapacious or sub-typical group of its order, we may expect to find the qualities of that group exalted or intensified, and accordingly made the more conspicuous. Such is really the case with the vultures, in the rapacious birds, a family remarkable above all of their order for their carnivorous and foul habits. So, also, if we take the typical group of the birds, the incessores or perchers, and look in it for its typical group, the conirostres, and seek there again for the typical family of that group, the corvidæ, we may expect to find a very marked superiority in organization and character. Such is really the case. “The crow,” says Mr. Swainson, “unites in itself a greater number of properties than are to be found individually in any other genus of birds; as if in fact it had taken from all the other orders a portion of their peculiar qualities, for the purpose of exhibiting in what manner they could be combined. From the rapacious birds this “type of types,” as the crow has been justly called, takes the power of soaring in the air, and of seizing upon living birds, like the hawks, while its habit of devouring putrid substances, and picking out the eyes of young animals, is borrowed from the vultures. From the scansorial or climbing order it takes the faculty of picking the ground, and discovering its food when hidden from the eye, while the parrot family gives it the taste for vegetable food, and furnishes it with great cunning, sagacity, and powers of imitation, even to counterfeiting the human voice. Next come the order of waders, who impart their quota to the perfection of the crow by giving it great powers of flight, and perfect facility in walking, such being among the chief attributes of the suctorial order. Lastly, the aquatic birds contribute their portion, by giving this terrestrial bird the power of feeding not only on fish, which are their peculiar food, but actually of occasionally catching it. [270] In this wonderful manner do we find the crow partially invested with the united properties of all other birds, while in its own order, that of the incessores or perchers, it stands the pre-eminent type. We cannot also fail to regard it as a remarkable proof of the superior organization and character of the corvidæ, that they are adapted for all climates, and accordingly found all over the world.
Mr. Swainson’s description of the zoological status of the crow, written without the least design of throwing any light upon that of man, evidently does so in a remarkable degree. It prepares us to expect in the place among the mammalia, corresponding to that of the corvidæ in the aves, a being or set of beings possessing a remarkable concentration of qualities from all the other groups of their order, but in general character as far above the corvidæ as a typical group is above an aberrant one, the mammalia above the aves. Can any of the simiadæ pretend to such a place, narrowly and imperfectly endowed as these creatures are—a mean reflection apparently of something higher? Assuredly not, and in this consideration alone Mr. Swainson’s arrangement must fall to the ground. To fill worthily so lofty a station in the animated families man alone is competent. In him only is to be found that concentration of qualities from all the other groups of his order which has been described as marking the corvidæ. That grasping power, which has been selected as the leading physical quality of his order, is nowhere so beautifully or so powerfully developed as in his hand. The intelligence and teachableness of the simiadæ rise to a climax in his pre-eminent mental nature. His sub-analogy to the feræ is marked by his canine teeth, and the universality of his rapacity, for where is the department of animated nature which he does not without scruple sacrifice to his convenience? With sanguinary, he has also gentle and domesticable dispositions, thus reflecting the characters of the ungulata, (the rasorial type of the class,) to which we perhaps see a further analogy in the use which he makes of the surface of the earth as a source of food. To the aquatic type his love of maritime adventure very readily assimilates him; and how far the suctorial is represented in his nature it is hardly necessary to say. As the corvidæ, too, are found in every part of the earth—almost the only one of the inferior animals which has been acknowledged as universal—so do we find man. He thrives in all climates, and with regard to style of living, can adapt himself to an infinitely greater diversity of circumstances than any other animated creature.
Man, then, considered zoologically, and without regard to the distinct character assigned to him by theology, simply takes his place as the type of all types of the animal kingdom, the true and unmistakable head of animated nature upon this earth. It will readily occur that some more particular investigations into the ranks of types might throw additional light on man’s status, and perhaps his nature; and such light we may hope to obtain when the philosophy of zoology shall have been studied as it deserves. Perhaps some such diagram as the one given on the next page will be found to be an approximation to the expression of the merely natural or secular grade of man in comparison with other animals.
