    is freely supplied with nerves which are principally derived frem the sympathetic] or ganglionic system; thus the Aorta and Pulmonary Artery, at their origin, are surrounded by branches from the Cardiac Plexus ; these are very pale and soft; the branches of the ex- ternal Carotid also are each enveloped by a plexus of nerves from the Sympathetic, branches of which may be traced on the coats of these vessels to a con- siderable distance; in like manner the Coronary Arteries of the Heart, the Spermatic Arteries, and those of the Abdominal Viscera, are each surrounded by a plexus of nerves, branches from which twine around these vessels and their ramifications. The arteries of the extremities have not so many or such large nerves for their supply, as those blood-vessels that are destined to nourish organs which have par- ticular functions to perform, or parts wdiich possess a peculiar or high degree of sensibility. When the nerves that form this plexus around the internal Carotid Artery, are traced as far as the Cavernous Sinus, they may be observed to pass off in different directions, and to unite with several of the Cerebral Nerves; two branches ascend to join the sixth pair of nerves in the Cavernous Sinus, a slight expansion, like a ganglion, marks the situation of their union on the external side of the Carotid Artery; the Ab- ducens Nerve is larger from this point to the Orbit than it was previous to this connexion with the Sym- pathetic; other branches of this plexus pass out- wardly, and join the ganglion or plexus of the fifth pair, particularly the Ophthalmic division of it; one branch of it may be observed to join the nasal twig
