Abstract

It has been noted in some mammals, and no doubt this is true for most species, that there is considerable variation from what is ordinarily understood as the normal condition in the origin and arrangement of certain arteries and veins. Such variations have been reported concerning the origin of groups of vessels, such as the arteries which arise from the systemic aorta and supply the head, neck and fore limbs. Similar conditions have been observed in the post cava and the venous system in general in some mammals. Even the blood vessels in man, both arteries and veins, are subject to a great many variations, or, what are sometimes called, abnormalities.
