The story of the ancient painter and the shoemaker is very well known.

The shoemaker set the painter right with regard to some mistakes he had made in the shoe of one of his figures, which the painter, who had not made such accurate observations on shoes, and was content with a general resemblance, had never observed.

But this was no impeachment to the taste of the painter; it only showed some want of knowledge in the art of making shoes.

Let us imagine, that an anatomist had come into the painter's working-room.

His piece is in general well done, the figure in question in a good attitude, and the parts well adjusted to their various movements; yet the anatomist, critical in his art, may observe the swell of some muscle not quite just in the peculiar action of the figure.
