    dissection of tlie muscle is continiiecl. Those from the six upper dorsal nerves appear near the mesial line, being derived from the inner branches of the- posterior divisions; the succeeding cutaneous nerves in both dorsal and lumbar region are farther out^ heing derived from the outer branches. The upper and lower borders of the latissimus dorsi muscle are to be made distinct from the subjacent parts ; the- origins from the ilium and lower ribs and from the- inferior angle of the scapula being all dissected out. In the interval between the trapezius and latissimus dorsi are to be noted a portion of the rJiomloideus- major and a portion of the thoracic wall, varying in. extent according to the position of the scapula. The trapezius muscle is to be divided bj means- of a vertical incision about an inch from the spines of the vertebrae ; and, in association with the dissec- tors of the head and neck, this incision may be con- tinued through the cervical part of the muscle. Oil its deep surface are the su])erficial cervical artery and spinal accessor!) nerve, which are on no account to be damaged, even by a junior dissector, but to be pre- served, so as to have their continuity from above dis- played by the dissectors of the head and neck. The rhomhoideus major and minor muscles are to be freed from fascia, care being taken not to injure their nerve,, as it passes beneath their upper border; and when those muscles have been divided by a vertical incision near their vertebral -extremity, this nerve (a branch from the fifth cervical), together with the posterior scapular artery, may be seen in its continjiity by the dissectors of the head and neck and upper limb
