Laterally. The sacro-lumbalis aids to raise the ribs upon the cervical vertebra?, and also draws the cervical vertebrae obliquely downwards. The serratus posticus superior lifts the ribs upward upon the spine, and draws the ribs firmly against the spine. The cervicis transversalis and the complexus help in sustaining the head and neck erect. The tracclo-mastoideus draws the head sidcwise, and draws the cervical spine towards the side of the head. The semi-spinalis colli aids in a powerful perpendicular traction against the cervical vertebra?. 2. In the dorsal region we find that the trapezius draws the scapula almost horizontally towards the spine, and the spine towards the scapula. The latissimus dorsi draws the shoulder towards the dorsal vertebras, likewise that portion of the spine towards the shoulder. The rhomboideus major here draws the scapula horizontally towards the vertebra, and the spine to the scapula. The serratus posticus superior simply lifts the ribs upon the spine, and the serratus posticus inferior depresses the ribs. The longissimus dorsi creates an oblique action in the whole dorsal portion of the spine, which is lateral and posterior. The spinalis dorsi holds the spine perpendicularly erect pos- teriorly. The tracclo-mastoideus draws the cervical vertebrae obliquely. The complexus draws the head backward, sets it firmly, and holds it erect. The splenius capitis draws the head towards the dorsal spine, and the dorsal towards the head. 3. In the lumbar region, we observe that the latissimus dorsi draws the shoulder down towards the lumbar region, and that portion of the spine to the shoulder. The serratus posticus inferior simply draws down the ribs. The sacro-lumbalis exerts a powerful oblique action in the whole of the lumbar, and in a part of the dorsal region. The longissimus dorsi exercises an oblique influence along the whole of the lumbar vertebra?. 4. In the scapular region, it is noticed that the trapezius draws the scapula upward and backward; that the levator an- guli scapula lifts the scapula towards the cervical region, and draws the spine downward towards the scapula; that the rhomboideus minor draws the scapula towards the dorsal spine, and the spine to the scapula; that the rhomboideus major
