The human feet are also different from those of all animals, even apes not excepted. The foot of the ape is rather a kind of aukward hand; its toes, or rather fingers, are long, and that in the middle longest of all; the foot also wants the heel. In man the sole of the foot is broader and more adapted to maintain the equilibrium of the body in walking, dancing, or running.

The nails are smaller in man than those of any animal. If they were much longer than the extremities of the fingers, they would obstruct the management of the hand. Such savages as suffer them to grow long, make use of them in flaying and tearing animals, but though their nails are considerably larger than ours, they are yet by no means to be compared to the hoofs or the claws of other animals.

There is little known exactly with regard to the proportion of the human figure, for the same parts do not bear similar proportions in any two individuals; nor even in the same, for seldom is it that the right leg or arm is of equal dimensions with the left. It is not by taking an exact resemblance that we can determine on the best proportion of the human figure; we must seek for it in taste and sentiment, which have exceeded the laws of mechanism in the imitation of Nature; and in which imitation we recognize her perfections more conspicuously than in her own productions; and by the same rule the beauty of the best statues is much better conceived by observation than by measurement. The ancients executed statues in so high a degree of perfection, that they have ever been considered as exact representations of the most perfect human figures. These statues, which were at first copied after the human form, are now considered as the most perfect models of it; and for this plain reason, that they were not formed after any one individual, but from a diligent observation of the perfect symmetry that was to be collected, as it were, from the whole species. In doing this, these artists also considered each part of the human frame should be of certain dimensions to become the standard of perfection; for instance, that the body should be ten times the length of the face; and that the face should also be divisible into three equal parts, the first form the hair on the forehead to the nose, the second the nose, and the third from the nose to the end of the chin. In measuring the body they use the term nose as the third of the face, one of which they reckon in height, from the top of the forehead to the crown of the head, therefore from the top of the head to the bottom of the chin is a face and one third, and from the chin to the upper part of the breasts two thirds more, which of course makes two tenths of the whole body; to the bottom of the paps another, to the navel a fourth, and from thence to the division of the lower extremities a fifth, or half the body; two more faces are assigned to the thighs, half a one to the knee, two from the knee to the top of the foot, and the other half from thence to the sole, which completes the ten. This division does not hold good in men of a more than ordinary size, in whom about half a face is allowed between the paps and the commencement of the thighs, which in them is not the middle of the body. The arms being stretched out, measure from the ends of the middle fingers ten faces, or exactly the length of the body. The hand is the length of the face, the thumb that of the nose, as is also the longest toe, and the bottom of the foot, is one sixth part of the length of the body. The space between the eyes is the breadth of the eye: the breadth of the thickest part of the thigh is double that of the thickest part of the leg, and treble the smallest. Were any individual measured by these rules, those we consider as the most perfect would be found highly deficient.

These correspondences are, however, extremely arbitrary. In infants the upper parts of the body are larger than the lower; the legs and thighs do not constitute any thing like half the length of the body; as the child increases in age the inferior parts increase more than in proportion, so that the body is not equally divided till it has acquired its full growth. In women the anterior part of the chest is more prominent than in men; but as in the former the chest is more thick, so in the latter it is more broad. In women too the hips are considerably more bulky, and so different is the conformation of those two parts, that it is sufficient to distinguish the skeleton of a woman from that of a man.

The total height of the human figure varies considerably. Men are said to be tall who are from five feet eight or nine inches to six feet. The middle stature is from five feet two to five feet seven inches; and such as fall under these measures are said to be of small stature. Women in general are two or three inches shorter than men. As for giants and dwarfs, of them we shall have occasion to speak in another place.

Though the body of a man is more externally delicate than that of any animal, it is exceedingly muscular, and for its size perhaps more strong. Were we to compare the strength of a lion with that of a man, we ought to consider that the former is armed with teeth and talons, which give a false idea of its power. The arms which man has received from Nature are not offensive; and happy were it if Art had never furnished him with weapons more terrible than those which arm the paws of the lion.

But there is another, and perhaps a more just manner of comparing the strength of man with that of animals, namely by the weights which either can carry. We are assured that the porters of Constantinople carry burthens 900 pounds weight; and M. Desaguliers tells us of a man in an upright posture, who, by distributing a certain number of weights, in such a manner that every part of his body bore its share, was able to support a weight of 2000 pounds. By the same expedient a horse, which is at least six or seven times our bulk, ought to be enabled to carry a load, of 12 or 14,000 pounds; an enormous weight in comparison of what that animal can support, even when the weight is distributed with every possible advantage.

The strength of a man may be still further estimated by agility and the continuance of his labour. Men accustomed to running outstrip horses, or at least continue their speed for a greater length of time. A man will walk down a horse if they continue together, and perform a long journey much sooner, and with less fatigue. The royal messengers of Ispahan, who are runners by profession, go 36 leagues in 14 or 15 hours. Travellers assure us, that the Hottentots out-run lions in the chace, and that the savages, who live by hunting, pursue the elk and other animals with such speed as to take them. Many other surprising things are told of the nimbleness of savages, and of the long journeys they accomplish on foot, over the most craggy mountains, and the most unfavourable roads, where there is no path to direct, and every obstacle to oppose. A thousand leagues are these people said to travel in less than six weeks, or two months. Birds excepted, whose muscles are indeed stronger in proportion than those of any other animal, no other creature could support such a continuance of fatigue. The civilized man is ignorant of his own strength; nor is he sensible how much he loses of it by effeminacy, and how he might add to it by the habit of vigorous exercise.

Sometimes we find men of extraordinary strength; but this gift of Nature, which would be valuable to them in a primitive state, is of very trifling service with the polished part of mankind, among whom mental perfections are held in higher estimation than bodily, and manual exertions are confined to persons of the lowest classes.

Men are much stronger than women; and this superiority they have too often employed, by tyrannically enslaving a sex, which was formed to partake with them the pleasures as well as the pains of life. Savage nations subject their women to a continued series of labour. On them is imposed every office of drudgery, while the husband indolently reclines in his hammock. From this inactive situation he is seldom roused but by the calls of hunger, when he is obliged to seek food by fishing or hunting. A savage has no idea of taking pleasure in exercise; and nothing surprises him more than to see an European walk backwards and forward, merely for his amusement or recreation. All men have a tendency to laziness; but the savages of hot countries are not only lazy to an extreme, but tyrannical to their women, beyond any other classes of men. In civilized countries men dictate laws to women, which are the more severe, as their manners are rough and untaught, and it is only among nations highly polished that women are raised to that equality of condition which is naturally their due, and so necessary to the true enjoyment of society. These refinements flow from themselves; and to strength they oppose arms more sure to conquer, when by modesty they teach us to pay homage to the empire of beauty; a natural advantage, superior to strength. But much skill is requisite to manage and increase its influence, as is evident from the different ideas which different nations entertain of beauty. These indeed are so widely opposite, so palpably contradictory, that there is every reason to suppose the sex have gained more by rendering themselves amiable, than even by this gift of Nature, about which men are so much divided. As from the difficulty of obtaining it, the value of a thing still increases, so beauty has always had its admirers, and its votaries, respect necessarily encreased as soon as the possessors of it maintained a becoming dignity, and turned a deaf ear to every address of which virtue was not the positive basis; this naturally introduced a delicacy of sentiment, and polished manners followed of course.
