 on this region might support the great toe in its change to the right direction.

Whether, and how far, this expedient might be advisable in very well-marked distortions and swellings ought, in every individual case, to be decided by an experienced surgeon.

I must now explain more particularly how the sole is to be constructed in such a case of permanent obliquity of the great toe, because a certain point must here be carefully attended to.

That is to say, the length of the foot is not to be taken in one measurement, for if so taken, the sole will be inevitably too short, but it must be taken in two parts, the first being the length from the heel to the joint at the root of the great toe, and the second the length from this joint to the point of the great toe. These two measurements must then be added to each other and laid down in a straight line, and the result will be the primary longitudinal line of the foot, which is employed in the further modelling of the sole exactly as directed in the previous section. Suppose, for example, that the sole of the foot for which a shoe is to be made has the form of the adjoining Figure, the length b a is to be measured first, and then that of
