![to consider the bones of the anencephalous monster nor those of the ape. The tarsal bones, then, at birth in the infant with an ordinary form of varus may be said to be unchanged in form, and to retain their normal characters; and in extreme varus, such as is rarely met with, the tarsal bones being plastic are readily moulded and brought into shape in treating the foot. But even in the anencephalous foetus the calcaneum is often found to be normal, and even the astragalus may scarcely show any deviation in form. Certain rotations of these tarsal bones occur, which are due to muscular retraction, and these vary as muscular retraction itself varies. The os calcis is rotated on its axis by the combined action of the extensors, and of the adductors on the bone itself and on the scaphoid, and through traction on the calcaneo- scaphoid ligament. Also the astragalus is neces- sarily rotated with the os calcis, and through the action of the extensors upon the latter it is thrust forward on to the dorsum, and thus it gains an oblique direction between the malleoli. Thus, in an extreme degree of varus the tarsal bones are not only rotated on their axes, but they may be wanting in development and also be mal- formed. But, as has already been said, these mal- formations occur only in the most severe forms of congenital varus. In such cases the interna]](https://iiif.wellcomecollection.org/image/b28089327_0015.jp2/full/800%2C/0/default.jpg)
