    f ;■ ■;' • ^ ■ A CONTRIBUTION TO tHE ANATOMY OF CONGENI- TAL EQUmfe-VARUS. By HERBERT L. BURRELL, M.D., OF BOSTON. The specimens which are illustrated in this article were obtained from a child born at seven months, and which lived for three or four hours. They were given me by Dr. W. N. Bullard. The right foot was normal. The left foot was in a position of moderate talipes equino-varus. The anterior part of the left foot could be corrected manually ; but the sole of the heel tended always to face inward. The axis of the foot was curved, with the concavity inward. The plantar fascia was but slightly contracted. Any attempt at correction of the deformity put the tendo Achillis, and the group of tendons lying behind the internal mal- leolus, viz., the flexor longus digitorum, flexor longus hallucis, and tibialis posticus, on the stretch. The skin over the tendons, as they crossed the inner border of the foot, was tense when the foot was in a corrected position. Dissectioii.—The skin over the inner border of the foot, where the internal group of muscles turn to reach the sole of the foot, was more adherent to the underlying tissues than in the normal foot. There was no difference in the size of the bellies of the muscles ; the sheaths of the tendons were apparently normal ; the plantar fascia was not markedly contracted, but became tense when the foot was brought into a corrected position. Astragalus.—The astragalus of the deformed foot was small; its neck was short; the axis curved with the concavity inward ; the articulation surface was anteriorly smaller than that of the normal astragalus. In the normal foot the articulating surface of the astragalus with the tibia was divided into three facets by two ridges ; in the deformed foot, where the astragalus articulated
