to the superior exactness of proportion in the fair sex.  Let us rest a moment on this point; and consider how much difference there is between the measures that prevail in many similar parts of the body, in the two sexes of this single species only.  If you assign any determinate proportions to the limbs of a man, and if you limit human beauty to these proportions, when you find a woman who differs in the make and measures of almost every part, you must conclude her not to be beautiful, in spite of the suggestions of your imagination; or, in obedience to your imagination, you must renounce your rules; you must lay by the scale and compass, and look out for some other cause of beauty.  For if beauty be attached to certain measures which operate from a principle in nature, why should similar parts with different measures of proportion be found to have beauty, and this too in the very same species?  But to open our view a little, it is worth observing, that almost all animals have parts of very much the same nature, and destined nearly to the same purposes; a head, neck, body, feet, eyes, ears, nose, and mouth; yet Providence, to provide in the best manner for their several wants, and to display the riches of his wisdom and goodness in his creation, has worked out of these few and similar organs, and members, a diversity hardly short of infinite in their disposition, measures and relation.  But, as we have before observed, amidst this infinite diversity, one particular is common to many species:  several of the individuals which compose them are capable of affecting us with a sense of loveliness:  and whilst they agree in producing this effect, they differ extremely in the relative measures of those parts which have produced it.  These considerations were sufficient to induce me to reject the notion of any particular proportions that operated by nature to produce a pleasing effect; but those who will agree with me with regard to a particular proportion, are strongly prepossessed in favor of one more indefinite.  They imagine, that although beauty in general is annexed to no certain measures common to the several kinds of pleasing plants and animals; yet that there is a certain proportion in each species absolutely essential to the beauty of that particular kind.  If we consider the animal world in general, we find beauty confined to no certain measures; but as some peculiar measure and relation of parts is what distinguishes each peculiar class of animals, it must of necessity be, that the beautiful in each kind will be found in the measures and proportions of that kind; for otherwise it would deviate from its proper species, and become in some sort monstrous:  however, no species is so strictly confined to any certain proportions, that there is not a considerable variation amongst the individuals; and as it has been shown of the human, so it may be shown of the brute kinds, that beauty is found indifferently in all the proportions which each kind can admit, without quitting its common form;
