    the perpendicular a c at the same distance from the floor as the point f. If, however, the extremity of his left hand were to exceed the perpendicular b d, the indicator would have to be moved back to the extent of the excess, and thereby the excess would be known. So likewise, if the dimensions of the extended arms were less than six feet, the indicator would have to be pushed forward, and thereby the quantity less than six feet would be known. In either of these two cases the highest part of his head would not come precisely under the point e, unless, indeed, one arm were longer than the other (which circumstance would have to be noted), but as the indicator for the head is five inches wide, sufficient space for even an extraordinary dissimilarity in the length of the two arms would be provided for. In like manner, the indicator that is to measure the ex- tent of the arms is five inches wide, that width being considered sufficient space for any even extraordinary deviation from the normal proportion of the length of the neck, which requires that the pit of the neck in a six-foot man should be 1 foot 1 inch from the crown of the head, the pit of the neck being on a level with the middle finger when the arms are extended horizontally. Another provision is to be made in the indicator for the sake of detecting more easily any deviation from the normal proportion in the length of the neck, and that is by painting a black line on the centre of the vertical surface of the indicator. The same provision is recommended to be adopted for the horizontal surface of the indicator that measures the
