    the pkntaris as it descended; and this circumstance, combined with its attachments, lias led me to regard it as an additional plantaris muscle ; but, as this conclusion may not be generally leceived, 1 have described it in this place.* The following abnormal muscle is probably a modification of the preceding. It arose from the depression above the external condyle of the femur, and above the origin of the plantaris, crossed the floor of the popliteal space beneath the popliteal vessels, and was inserted by tendinous fibres into the lifjamentum posticum Winslowii. The muscle was as large as the plantaris. Muse. Adductor Longus.—This muscle was once observed di- vided into two throughout its whole length. The two divisions were placed side by side, the superior being the smaller. The lower perforating artery sent off, in this subject, from the great muscular branch of the superficial femoral, passed to the back of the thigh, between the two portions near their insertions into the femur. Muse. Adductor Brevis.—The following supernumerary ad- ductor of the thigh may be considered a variety of the short ad- ductor, and, as such, I shall describe it. It arose from the as pubis, immediate above and in front of the origin of the adductor brevis^ and, passing outwards, downwards, and backwards, first in front of the adductor brevis, and then behind the pectineus, was inserted into the posterior part of the small trochanter, behind the psoas and iliacus.t Muse. Gastrocnemius.—This muscle received a slip of mus- cular fibres, about one inch in breadth, from the head of the fibula above the origin of the soleus. This slip of muscle was inserted into the tendinous part of the outer head of the gastrocnemius, near its union with the soleus, to form the te?ido Aeliillis. Muse. Soleus.—The tendency to the doubling of this muscle, by splitting in the direction of its length, was noticed in three subjects, but not to the same degree as in those described in my first report. Muse. Flaritaris.—Thai Meckel must have fallen into error when he stated that the plantaris was more inconstant than the pnlmaris lonqvs, is evident from the observations of Gautzer, and from the fact, that while the palmaris longns was often_ wanting, the plantaris was only absent once in the whole 200 subjects over which my observations extend. The following varieties of this muscle are somewhat remarkable. In a male subject, in which several anomalies by deficiency were detected, the'plantaris was found to have two heads, separated • A cast of this variety is placed in the museum of the University, t A cast of this supernumerary adductor is preserved ui the museum ot the University.
