Henry Ogg Forbes, A Hand-book to the Primates — Introduction (1894)

“ Notwithstanding the numerous varieties and races of mankind distributed over every region of the globe, each exhibiting differences in habits, customs and superficial complexion, Man forms but one species, Homo sapiens, the sole representative of the unique genus of his family. Though the genus Homo is thus far apparently zoologically isolated, there is a remarkable group of animals, which we designate "Apes," and which, possessing many of the same structural characters more or less modified, stand apart from all the other Mammalia, and make a distinct approach to Man. ”

“ The upper part of the windpipe is, in all Primates, modified to form the larynx, or organ of voice, constituted by fibrous strings stretched across its orifice, where they may be set in vibration by the air, in its passage to and from the lungs.
The brain is relatively large in proportion to the body, and attains in the higher of the two sub-orders its most perfect development. ”

“ Lying beneath the lower jaw is the hyoid arch, a slender framework of bones, supporting the tongue and the upper end of the windpipe with the organ of voice. In a few of the Monkeys and Apes certain of the bones of this arch are much enlarged and hollowed for increasing the volume of sound emitted by them. On either side of the great opening which is so conspicuous at the hinder part of the skull, for the reception of the spinal cord, is a smooth kidney-shaped surface, called a "condyle." ”

“ Between Man, however, and the Apes, even the untrained eye at once perceives, amid obvious marks of inferiority, unmistakable resemblances, while anatomical investigations reveal that "the points in which Man differs from the Apes most nearly resembling him, are not of greater importance than those in which the Ape differs from other and universally acknowledged members of the group." ”

“ In common with all other Mammals, the Primates are furnished with an epidermal covering, which, except in Man, consists of a woolly or hairy fur. They possess four limbs and a tail, which may be long, short, or concealed, and which is often used as a prehensile organ. ”

“ Man, in respect of his mental endowments, stands alone and unapproachable among living creatures. Considered as to his "place in nature," however, he must be described as an erect-walking Mammal, possessing anterior extremities developed into hands of great perfection, for exclusive use as tactile and grasping organs, and posterior limbs, on which his body is perfectly balanced and entirely supported, exclusively devoted to locomotion, as well as highly specialised cerebral characters. ”

“ The Primates are Diphyodont [4] as well, because many of their permanent teeth are preceded by another set, commonly known as the milk-teeth. In order to present to the eye at a glance the number of each sort that any species possesses, a dental formula has been adopted by naturalists. Such a formula as I 2/2, C 1/1, P 3/3, M 3/3 = 36, indicates that in one half of the mouth, above and below, there are 2 incisors, 1 canine, 3 pre-molars, and 3 molars = 18; and therefore in the two halves of the mouth together there are 36 teeth in all. ”

“ The young are born in a condition of greater or less helplessness, with their eyes, as a rule, unopened, and the framework of their bodies incompletely ossified, and consequently requiring protective care and entire nourishment from the mother, for a considerable period. At maturity this skeleton consists of a skull, a breast- and a back-bone of many pieces, ribs, jointed limbs, and a pair of collar-bones. ”

“ The stomach and intestines, with other important structures, such as the liver, kidneys and generative organs, are contained in a lower cavity, separated by a muscular midriff, the diaphragm, from the upper part or thorax, containing the blood-purifying and pumping organs, the lungs and the heart. ”

“ The surface of its lateral halves, which are connected by transverse bands so as to insure harmony of action between them, is marked by fissures and foldings, or convolutions, which vary in number and complexity, evidently in relation to the intelligence of the animal. The brain within the skull gives origin to the nerves for the chief organs of sense ”
