    acromion process of the human scapula. The two regions separated by the spine are known as the supraspinous fossa and the infraspinous fossa. The supraspinous fossa is anterior to the spine, and the infraspinous is posterior to it. The surfaces of the scapula are, in quadrupeds, flatter than in the human being, and in particular the subscapular fossa, which is also less concave. Some authors attribute this to the lesser curvature of the ribs in quadrupeds. A few words Fig. 14.—Vertical and Transverse Section, at the Site of the Shoulders, of the Thorax of the Horse (Diagrammatic Figure). 1, Outline of the thorax at the level of the third dorsal vertebra ; 2, 2, scapula ; 3, spinal border of the scapula ; 4, cartilage of prolongation ; 5, contour of the skin.

The scapula is not in immediate contact with the ribs ; the subscapular fossa is not moulded on them. Besides, the form of the scapula is, as in other parts of the skeleton, dependent on the disposition of muscles, and the develop- ment of these latter is correlated to the extent and energy of the movements which the individual is able or required
