Actual Size 14 X 8 mm.] the hindlimb in gibbon and the high degree of proficiency attained by the upper extremity and hand, especially for the purposes of its fleet locomotion, give marked structural preponderance to the nucleus of Blumenau. The prominence of the inferior oIi\ary nucleus compared with the other forms may also be in direct relation with the Ilight-Iike locomotion ol the animal.
