    The right lung is most easily incised by placing it in the same position, but with the apex toward the operator; in other words, always place the anterior edge of a lung beneath the palm of the hand. Some prefer to place each lung on its lower or diaphragmatic surface for incision. The right middle lobe is incised separately by a cut extending trans¬ versely in its greatest diameter. The bronchi and blood-vessels should be opened up for some distance with small probe-pointed scissors—as a rule from the surface of the section—cutting through the over- lying lung-tissue. In some cases, however, it is best to open up both the blood-vessels and the bronchi from the outside of the lung before incising it. The order to follow is vein first, then artery, and finally the bronchus. Secondary cuts into the lung are to be made parallel to the main incision. The bronchial lymph-nodes should be incised from the outside of the lung. Organs of the Neck.—The operation of the removal of the organs of the neck is greatly facilitated if it is pos¬ sible to continue the primary skin-incision up to the chin. In other cases dissect the skin from the larynx and muscles of the neck as far up as possible. In like manner free the muscles, esophagus, and trachea from their attachments later¬ ally and posteriorly. Then allow the head to drop well back over the end of the table, and pass a long, slender-bladed knife up between the skin and the larynx, just behind the symphysis of the lower jaw, until the point of the knife appears beneath the tip of the tongue. From this point the knife is carried with a sawing motion down first one ramus of the jaw and then the other, dividing laterally the glossal muscles as far back as the posterior pharynx. The knife is next carried up behind the esophagus, and the posterior wall of the pharynx divided as high as possible. Pass the left hand up inside of the neck and draw down the tongue. Then cut the attachments of the soft to the hard palate, carrying the knife well out so as not to injure the tonsils. Any remaining attachments are usually easily severed by
