draws the scapula horizontally to the dorsal spine, and that por- tion of the spine to the scapula. 5. In the costal region, it is ob- served that the latissimus dom tends, on the whole, to draw the dorsal spine into an oblique lateral posi- tion ; that the sacro-lmnbalis tends to hold the spine erect, and also make an oblique action in the lum- bar vertebrae. The serratus posticus superior and the cervicalis ascendens tend to lift the ribs, and draw the cervical spine obliquely over and downward. 6. In the abdominal region, we see the external oblique, acting pow- erfully in the direction of its fibres, from the pubis towards the scapula; that the rectus abdominis acts per- pendicularly in and near the ante- rior median line; that the internal oblique produces a deep together- drawing that radiates from the crest 2.

In the pelvic region, the latis- simus dorsi is seen to draw the whole spine from the upper dorsal to the lower lumbar vertebras, together with the ribs, in an oblique downward direction ; and that the longissimus dorsi has a decided indirect action,
