    Drawing on the law of refraction of light the notes state that a 'brilliant sally from an encephalon of a rare wit, striking upon the denser medium of the thick skull of a blockhead, becomes refracted; the angle of refraction being equal, &c'. This is supposed to prove the adage, 'in at one ear and out at the other'. The illustration depicts this apparent new law of physics.
