Inhalation of the fumes of phosphorus gives rise to a form of periosteitis which ends in necrosis of the bone. The bones of the jaws are most liable to be affected. Periosteitis. 1036. The periosteum, being a vascular membrane, is of course liable to inflammation, sometimes the result of injury but more frequently associated with the strumous or syphilitic diathesis. Suppurative periosteitis is often of a septic nature. Inflammatory affections of bone and its membranes are also more common in youth than in adolescence or old age. Simple Periosteitis.--In that, for instance, resulting from a blow upon the shin, the membrane becomes hypera'mic, its deep layer proliferates, and inflammatory products infiltrate its substance. They tend to accumulate in its deep layer; there is comparatively little exudation between the bone and the membrane. The bone, if affected at all, sutlers only superficially. The effusion may be expected to disappear after the acute hyperemia has subsided, and little trace of the afl'ection remains. In some cases a ridge of Ikiuo is left, from the accumulated osteoblasts having ossified. This is a common affection in horses, the ridge being known as a splint. Suppurative Variety.--A much more serious disease is where the effusion accumulates between the bone and its enveloping membrane and suppurates. This suppurative form of the disease is commnionest in youth and mostly in boys. The humerus is a bone which, for some unknown reason, suffers frequently from it. The membrane is stripped off from the bone and is converted into an abscess sac. An entire shaft may thus be laid bare. The pus is of a greenish colour and teems with the organisms of suppuration...
