    like process at the under part of the astragalus is received into the hollow between the two articular surfaces of the os calcis ; the astragalus projects on the outei part of the foot; the fibula may or may not be fractured ; the vacuity at the inner and hinder part of the foot will be greater than in dislocations forwards ; and the foot is inverted. In partial dislocation inwards, the outer hook-like process of the posterior articular surface of the under part of the astragalus, is received into the inner part of the rough depression between the calcaneal articulating facets. The astragalus will project at the inner side, and there will be a void at the upper and outer part of the foot. In these lateral luxations the foot will be turned either outwards or inwards, but more frecpiently inwards, and the heel is raised. In partial dislocation backwards, the inner pointed process of the astragalus passes into the depression which is situated behind the acute summit of the posterior edge of the posterior articular facet of the os calcis, and between it and the elevated ridge at the upper part of the tuberosity of the heel. The bones of the leg may be carried a little forwards, or backwards, according to the state of the ligaments; the length of the heel will be accordingly increased or diminished ; and in the latter case, a vacant place will be seen at the fore part of the ankle joint. In these cases, it is to be presumed that the heel will be but triflingly raised, and the foot but slightly inverted. In complete and direct luxation forwards, the bone is tilted out, so as to rest partly on the navicular.
