    occipital groove of the temporal bone, tlie posterior auricular artery, the lingilal ai-tery as far as the border of the hyoglossu^ muscle, and the fticial arteiy as far. as the lower jaw; he will also lay bare the pneumogastric nerve as far as convenient, tracing the superior and external laryngeal branches. In the lower part of the neck, the subclavian artery is now to be examined in the three parts of its coui'se; and the different relations of the subclavian and common carotid arteries in the first part of their courses on the two sides of the body are to be carefully compared. The internal jugular and the subclavian veins, with the branches joining*them, are to be dissected, and on the left side the arched pai't of the thoracic duct descending into the angle of jiinction of these two veins. The branches of the subclavian artery are to be displayed, viz., the vertebral and internal mammary arteries, the thyroid axis, from which arise the inferior thyroid giving off the ascending cervical artery, the suprascapular artery, and most frequently the transverse cervical dividing into the superficial cervical and posterior scapular; lastlj', there are the deep cervical and superior intercostal arteries coming off either as a single trunk or separately. The frequent origin of the posterior scapular artery from the third part of the subclavian artery and other varieties will here require to be attended to. The trunk of the sympathetic nerve is to be dis- sected, with its three cardiac and its other branches, as high as the first cervical nerve; and the recurrent laryngeal branch of the vagus nerve is to be found between the gullet and trachea., and traced up to the larnyx. 5. Superficial Dissection of the Face.—In proceeding with this region, the dissectors ought to expose in concert the su])er- ficial muscles of the ftice on one side, keeping only the principal blood-vessels and nerves. They ought likewise to make a more . detailed exposure and dissection of these vessels and nerves on the other side, for which purpose the superficial muscles must be in some measure sacrificed. If this plan cannot be carried out in concert, each dissector must display as much as possible all tlie parts on his own side, in which case he will begin with the superficial muscles.
