    the vessel included between its origin and the tra¬ cheal side of the scaleni muscles) varies in its length according to the part of the aorta from whence it takes its origin: it may, however, generally he about two inches. The Arteria innominata in the course described, * has on its left side the trachea, on the right side, and partly in front, the Vena innominata of the same side, directly in front the left Vena innominata; is separated from the sternum by this vein, and by the inferior attachments of the sterno-hyoid and thyroid muscles ; posteriorly it is separated from the vertebral column by cellular substance, and by numerous twigs of nerves ; moreover, we find it closely encircled by small branches of nerves from the sympathetic ganglia of the neck, which pass downwards to form part of the cardiac nerves. The left Carotid, in the situation mentioned, has on its right side the trachea, on its left the Sub¬ clavian ; in front the left Vena innominata, and be¬ hind it, is separated from the spinal column by the oesophagus, as it projects to the left behind the trachea, and by nerves and cellular substance ; and also we have between the artery and vertebrae the thoracic duct, as it is passing upwards, in its usual course, to join the Subclavian vein.
