Meyer, of Zurich, first directed attention to the fact that in a normal human foot a line drawn from the center of the os calcis through the center of the metatarsophalangeal joint of the great toe, would pass through the center of the distal phalanx of that toe; and further, that a line through the center of each one of the toes should converge at the same point. This line has ever since been called Meyer's line and possesses great value in comparing the positions that feet assume with those that are normal in construction and function.
