Rh ilium, but both were inserted together into the back of the femur.

"A single median gracilis arose from the symphysis of the ilia, and was inserted into the tibia in' front between the two tuberosities.,

"The extensor muscles of the leg, namely, the rectus and vasti, were found in double series; the recti arising as usual from the pelvis, and the vasti from the lateral portions of the femur; each series was inserted into a corresponding patella, and by means of their respective ligaments into the right and left tuberosities of the tibia. Thus each set of extensors became a flexor with reference to the other. A biceps on each side was inserted into the top of the fibula. Besides this last-mentioned muscle, there were no other proper flexors of the leg.

"On each side of the tibia was a tibialis anticus, but both were inserted into the top of the foot by a common tendon.

"An extensor communis on each side of the tibia was inserted into the three corresponding toes, and a slip was given from each to the symmetrical toe.

"A peroneus brevis was inserted to the outer sides of the foot.

"A single gastrocnemius was present, but no soleus.

"A flexor communis longus on each side was inserted into the toes in the same order as the extensors.

"Nerves of the Arm.—A brachial plexus, consisting of five pairs of nerves, is given off from each neck, namely, from the left side of A and the right of B, and, with the exception of the internal cutaneous nerves, the branches of the two sides keep separate. In the axilla each plexus gives off a circumflex and an external cutaneous nerve, the latter perforating the supinator longus at the lower part of the arm. The two external cutaneous nerves unite and descend the back of the arm on the median line. The remaining branches of the brachial plexus pass on each side between the long head of the triceps and the humerus, descend on the sides of the arm, form the musculo-spiral, radial, and ulnar nerves, which last two are distributed to the backs of the hand. No median nerve was found.
