Health lectures for the people . ulders renders them veryliable to injury. Indeed, fracture ofthe collar-bone, and bruises and disloca-tion of the shoulder-joint, are about thecommonest injuries that come underthe notice of the surgeon. I dont think that we would readily admit any superiority of carriage in French women as compared with the women of our own country. Still it has been asserted that in the former the collar-bones are slightly longer, and that they are thereby enabled to carry themselves with more grace. The shoulder-Made is a flat triangular bone which lies upon theback of the upper part of the chest. At no point is it directlyjointed to the bones of the trunk. Indeed, the only direct articu-lation between the upper limb and the trunk is where the collar-bone is jointed to the breast-bone. In the upper-arm there is a single long bone—the arm-bone orhumerus. The rounded upper end of the arm-bone rolls in ahallow concavity or socket which. is developed on the upper andouter angle of the Fig. 15.

THE HUMAN BODY. 49 In the forearm we find two bones placed side by side andextending from the elbow to the wrist. Of these the outer istermed the radius, and the inner the ulna. At the elbow-jointthe ulna is very extensively connected with the arm-bone orhumerus; indeed it holds the lower end of the latter in a deepcrescentic concavity. The upper end of the radius is very small,somewhat disc-shaped, and in contact with the lower end of thehumerus by its upper surface alone. If we now compare the lowerends of the bones of the forearm, we notice that the lowerextremity of the radius is broad and expanded, and takes thechief part in supporting the hand, whilst the lower end of theulna is small and button-shaped, and is separated from the bonesof the wrist by a triangular piece of cartilage or gristle. Whilstthen the ulna has a greater share in the co
