As the great botanist Bichat long ago said, if everyone were cast in the same mould, there would be no such thing as beauty. If all our women were to become as beautiful as the Venus de’ Medici, we should for a time be charmed; but we should soon wish for variety; and as soon as we had obtained variety, we should wish to see certain characteristics in our women a little exaggerated beyond the then existing common standard.
