As soon as the floor of the mouth is opened and the tongue loosened from the lower jaw the left hand is introduced beneath the skin, through the incision, into the mouth, and the tongue seized by thumb and middle finger, and drawn forcibly downward, while the other fingers are used to lift up the skin from the knife. The long section-knife, with cutting edge turned toward the left, is then introduced in the median line, along the left hand, until its point reaches the hard palate, taking care to work the point back slowly until it reaches the border between soft and hard palate. This must be done by feeling rather than by sight. The block under the neck is then pushed up under the head and the chin thrown forward so that the point of the knife is directed at right angles against the cervical vertebræ. The soft palate is then cut to the left, while the tongue is pulled firmly downward and toward the right, putting the uvular arch on a stretch so that the knife passes around the left tonsil. The knife is then turned and the same cut made on the right, severing the right faucial pillar and tonsil, while the tongue is pulled downward and to the left. The point of the knife is then pushed back to the pharyngeal wall and the latter is cut from right to left by a strong, firm stroke directed at right angles to the surface of the upper cervical vertebræ. The cut through the pharyngeal mucosa should be at the level of the boundary between the laryngeal and nasal portions, at about the height of the axis. While this cut is being made firm traction should be kept up on the tongue, pulling it downward, and alternately to the left and right. The loose retropharyngeal and retroœsophageal fascia tears easily and the mouth organs can now be pulled so far downward that first transverse and then oblique cuts through this fascia can now be made upon the vertebræ, severing the vagi, carotids and jugulars, and working from above downward, until the mouth and neck organs can be lifted up through the skin-incision and the entire mass of the neck-organs separated from the spinal column as far as the clavicles. Pulling the mass toward the right, the left subclavian vessels and fascia are severed by a cut directed downward and outward beneath the clavicle. Traction is then made toward the left and the right subclavians cut beneath the clavicle. If the thoracic organs have been removed the œsophagus and aorta may now be stripped down to the diaphragm and there cut off, or the neck-organs may be cut off at the level of the bifurcation of the bronchi.
