It is particularly worth observation that the more we magnify, by the assistance of glasses, the works of nature, the more regular and beautiful they appear, while it is quite different in respect to those of art, for when they are examined through a microscope we are astonished to find them so rough, so coarse and uneven, although they have been done with all imaginable care, by the best workmen. [ Sterne ]

If the eye were so acute as to rival the finest microscope, and to discern the smallest hair upon the leg of a gnat, it would be a curse, and not a blessing to us; it would make all things appear rugged and deformed; the most finely polished crystal would be uneven and rough; the sight of our own selves would affright us; the smoothest skin would be beset all over with rugged scales and bristly hair.
