Our necessities have taught us to mould matter into various shapes, and to give them fit proportions for particular uses, as bottles, glasses, knives, dishes, &c. Hath not offence given rise to the form of the sword, and defence to that of the shield? And what else but proper fitness of parts hath fix'd the different dimensions of pistols, muskets, great guns, fowling-pieces and blunderbusses; which differences as to figure, may as properly be called the different characters of fire-arms, as the different shapes of men are called characters of men.
We find also that the profuse variety of shapes, which present themselves from the whole animal creation, arise chiefly from the nice fitness of their parts, designed for accomplishing the peculiar movements of each.
And here I think will be the proper place to speak of a most curious difference between the living machines of nature, in respect of fitness, and such poor ones, in comparison with them, as men are only capable of making; by means of which distinction, I am in hopes of shewing what particularly constitutes the utmost beauty of proportion in the human figure.
A clock, by the government's order, has been made, and another now making, by Mr. Harrison, for the keeping of true time at sea; which perhaps is one of the most exquisite movements ever made. Happy the ingenious contriver! although the form of the whole, or of every part of this curious machine, should be ever so confused, or displeasingly shaped to the eye; and although even its movements should be disagreeable to look at, provided it answers the end proposed. An ornamental composition was no part of his scheme, otherwise than as a pollish might be necessary. If ornaments are required to be added to mend its shape, care must be taken that they are no obstruction to the movement itself, and the more as they would be superfluous, as to the main design.—But in nature's machines, how wonderfully do we see beauty and use go hand in hand!
Had a machine for this purpose been nature's work, the whole and every individual part would have had exquisite beauty of form without danger of destroying the exquisiteness of its motion, even as if ornament had been the sole aim; its movements too would have been graceful, without one superfluous tittle added for either of these lovely purposes.—Now this is that curious difference between the fitness of nature's machines (one of which is man) and those made by mortal hands: which distinction is to lead us to our main point proposed; I mean, to the shewing what constitutes the utmost beauty of proportion.
There was brought from France some years ago, a little clock-work machine, with a duck's head and legs fixt to it, which was so contrived as to have some resemblance of that animal standing upon one foot, and stretching back its leg, turning its head, opening and shutting its bill, moving its wings, and shaking its tail; all of them the plainest and easiest directions in living movements: yet for the poorly performing of these few motions, this silly, but much extoll'd machine, being uncover'd, appeared a most complicated, confused, and disagreeable object: nor would its being covered with a skin closely adhering to its parts, as that of a real duck's doth, have much mended its figure; at best, a bag of hob-nails, broken hinges, and patten-rings, would have looked as well, unless by other means it had been stuffed out to bring it into form.
Thus again you see, the more variety we pretend to give to our trifling movements, the more confused and unornamental the forms become; nay chance but seldom helps them.—How much the reverse are nature's! the greater the variety her movements have, the more beautiful are the parts that cause them.
The finny race of animals, as they have fewer motions than other creatures, so are their forms less remarkable for beauty. It is also to be noted of every species, that the handsomest of each move best: birds of a clumsy make seldom fly well, nor do lumpy fish glide so well through the water as those of a neater make; and beasts of the most elegant form, always excel in speed; of this, the horse and greyhound are beautiful examples: and even among themselves, the most elegantly made seldom fail of being the swiftest.
The war-horse is more equally made for strength than the race-horse, which surplus of power in the former, if suppos'd added to the latter, as it would throw more weight into improper parts for the business of mere speed, so of course it would lessen, in some degree, that admirable quality, and partly destroy that delicate fitness of his make; but then a quality in movement, superior to that of speed, would be given to him by the addition, as he would be render'd thereby more fit to move with ease in such varied, or graceful directions, as are so delightful to the eye in the carriage of the fine manag'd war-horse; and as at the same time, something stately and graceful would be added to his figure, which before could only be said to have an elegant neatness. This noble creature stands foremost among brutes; and it is but consistent with nature's propriety, that the most useful animal in the brute-creation, should be thus signalized also for the most beauty.
Yet, properly speaking, no living creatures are capable of moving in such truly varied and graceful directions, as the human species; and it would be needless to say how much superior in beauty their forms and textures likewise are. And surely also after what has been said relating to figure and motion, it is plain and evident that nature has thought fit to make beauty of proportion, and beauty of movement, necessary to each other: so that the observation before made on animals, will hold equally good with regard to man: i. e. that he who is most exquisitely well-proportion'd is most capable of exquisite movements, such as ease and grace in deportment, or in dancing.
