These are at first situated between the perforatus ami perforans tendons, and reach the superior extremity of the interdigital spaces, where they receive the metacarpal interosseous arteries, and comport themselves in the fol- lowing manner: the internal goes to the thumb; the secojid—counting from within outwards—gains the con- centric side of the index; the third, the largest, divides into tw^o branches which lie alongside the great digits; the last goes to the external digit. COMPARISON OF THE AXILLARY ARTERIES IN MAN WITH THOSE OF ANIMALS. The arteries of the thoracic limbs and head arise sepa- rately from the arch of the aorta; consequently, in Man there is no anterior aorta. The vessel of the limb that represents the axillary of animals is here resolved into two portions : the stibclavian artery and axillary artery. The SUBCLAVIAN ARTERY has uot the same oiigin on both sides; on the right it arises from the aorta by a trunk common to it and the carotid of that side—tlie brachio- cephalic trunk {arteria innominata); while the left is detached separately from the most distant part of the aortic arch.
