СКАЧАТЬ Galen, “is furnished with hands, as he alone is a participator in wisdom. The hand is a most marvellous instrument, and one most admirably adapted to his nature. Remove his hand, and man can no longer exist. By its means he is prepared for defence or attack, for peace or war. What need has he of horns or talons? With his hand, he grasps the sword and lance, he fashions iron and steel. Whilst with horns, teeth and talons, animals can only attack or defend at close quarters, man is able to project from afar the instruments with which he is armed. Shot from his hand, the feathered arrow reaches at a great distance the heart of an enemy, or stops the flight of a passing bird. Although man is less agile than the horse and the deer, yet he mounts the horse, guides him, and thus successfully hunts the deer. He is naked and feeble, yet his hand procures him a covering of iron and steel. His body is unprotected against the inclemencies of climate, yet his hand finds him a convenient abode, and furnishes him with clothing. By the use of his hand, he gains dominion and mastery over all that lives upon the earth, in the air, or in the depths of the sea. From the flute and lyre with which he amuses his leisure, to the terrible instruments by means of which he deals death around him, and to the vessel which bears him, a daring seaman, upon the bosom of the deep—all is the work of his hand.

      “Would man without hands have been able to write out the laws which govern him, or raise to the gods statues and altars? Without hands could he bequeath to posterity the fruit of his labours, and the memory of his deeds? Could he (had man been created handless) converse with Socrates, Plato, Aristotle, and the different great men, children of bygone ages? The hand is then the physical characteristic of man, in like manner as intelligence is his moral characteristic.”

      Galen, having shown in this chapter the general formation of the hand and the special disposition of the organs which compose it; having described the articulations and bones, the muscles and tendons of the fingers; and having analyzed the mechanism of the different movements of the hand, cries, full of admiration for this marvellous structure:

      “In presence of the hand, this marvellous instrument, cannot we well treat with contempt the opinion of those philosophers who saw in the human body merely the result of a fortuitous concourse of atoms! Does not everything in our organization most clearly give the lie to this false doctrine? Who will dare to invoke chance in explanation of this admirable disposition? No, it is no blind power that has given birth to all these marvels. Do you know among men a genius capable of conceiving and executing so perfect a work? There exists not such a workman. This sublime organization is the creation of a superior intelligence, of which the intellect of man is but a poor terrestrial reflection. Let others offer to the Deity reeking hecatombs, let them sing hymns in honour of the gods; my hymn of praise shall be the study and the exposition of the marvels of the human frame!”

      The sense of hearing, without attaining in man the perfection which it reaches in certain animals, is nevertheless of great delicacy, and becomes an infinite resource of instruction and pure enjoyment. Not only are differences of intonation, intensity, and timbre, recognised by our ear, but the most delicate shades of rhythm and tone, the relations of simultaneous and successive sounds which give the sentiment of melody and harmony, are appreciated, and furnish us with the first and most natural of the arts—music. Thus the perfection and delicacy of our senses, which permit of our grasping faint and slightly varying impressions, the harmony of these senses themselves, their perfect equilibrium, their capability of improvement by exercise, place us at a considerable distance above the animal.

      Let us now pass to the bony portion of the human body, and consider first of all the head. The head is shared by two regions, the cranium and the face. The predominance of either of these regions over the other, depends upon the development of the organs which belong to each.

      The cranium contains the cerebral mass, that is, the seat of the intellect; the face is occupied by the organs appertaining to the principal senses. In animals, the face greatly exceeds the cranium in extent; the reverse is, however, the case with man. It is but rarely that with him the face assumes importance at the expense of the cranium—in other words, that the jaws become elongated, and give to the human face the aspect of a brute.

      We find in works upon anthropology some expressions which call for an explanation here; they are frequently employed, since they enable us to express by a single term the relation which exists between the dimensions of any particular skull. The term dolichocephalous (from the Greek δολιχος, long, κεφαλη, head,) is applied to a cranium which is elongated from front to rear, or, to express the idea numerically, the cranium whose longitudinal diameter bears to its vertical diameter the proportion of 100 to 68. A short cranium is styled brachycephalous (from βραχυς, short, κεφαλη, head,) which term is applied when the relation between the longitudinal and vertical diameters is 100 to 80.

      The attribute of length or shortness of the cranium is of less importance than is generally believed. All Negroes, it is true, are dolichocephalous; but it must not be supposed from this that the production backwards of the cranium is an indication of inferiority; since in the white race, heads are sometimes very long and sometimes very short. The North Germans are dolichocephalous; those inhabiting Central Germany being brachycephalous. This characteristic cannot therefore be regarded as a criterion of intellectual excellence.

      There is in the human face an anatomical characteristic of greater importance than any taken from the elongation of the cranium; that is, the projection forwards, or the uprightness of the jaws. The term prognathism (from προ, forward, and γναθος, jaw,) is applied to this jutting forward of the teeth and jaws, and orthognathism (from ορθος, straight, γναθος, jaw,) to the latter arrangement.

      It was long admitted that prognathism, or projection of the jaws, was peculiar to the Negro race. But this opinion has been forced to yield to the discovery, that projecting jaws exist among people in no way connected with the Negro. In the midst of white populations this characteristic is frequently met with; it is occasionally found among the English, and is by no means rare at Paris, especially among women. Prognathism would appear to be characteristic of a small European race dwelling to the south of the Baltic Sea, the Esthonians, and which itself is but the residue of the primitive Mongolian race to which we have alluded in our work, “Primitive Man,” as being the first race which, according to M. Pruner-Bey, peopled the globe. It is probably the mixture of Esthonian blood with that of the inhabitants of Central Europe, which causes the appearance in our large cities of individuals whose faces are prognathous.

      We cannot close our remarks upon the face without speaking of a curious relation between it and the cranium, which has been much abused; we allude to the facial angle. By facial angle is meant the angle which results from the union of two lines, one of which touches the forehead, the other of which, drawn from the orifice of the ear, meets the former line at the extremity of the front teeth.

      The Dutch anatomist Camper, after having compared Greek and Roman statues, or medals of either nationality, assumed that the cause of the intellectual superiority which distinguished Greek from Roman physiognomies was to be found in the fact, that, with the Greeks, the facial angle is larger than in Roman heads. Starting with this observation, Camper pursued his enquiries until it occurred to him to advance the theory that the increase of the facial angle may be taken in the human race as a sign of superior intelligence.

      This observation was correct, insomuch as it separated men from apes, and carrion birds from other birds. But its application to different varieties of men, as a measure of their various degrees of intelligence, was a pretension doomed to be sacrificed to future investigations. Dr. Jacquart, assistant-naturalist in the Museum of Natural History at Paris, calling to his aid an instrument he invented, by which the facial angle is rapidly measured, has, in our day, made numerous studies of the facial angle of human beings. M. Jacquart found that this angle cannot be taken as a measure of intelligence, for he observed it to be a right angle in individuals, who, with respect to intelligence, were in no way superior to others whose facial angle was much СКАЧАТЬ
