The third phase is characterised by fractures, and it is this pecuHarity of the disease which has procured for it the names of fragi- litas ossium, and osteoclastia. These fractures may affect any portion of the skeleton. Animals so suffering sometimes break a leg whilst trotting or the pelvis in simply jumping over a ditch; a collision with a fixed object like the jamb of the stable door, or a fall on the ground, may result in the fracture of one or several ribs. Such shocks would be of no importance to a healthy animal, but to one sufl'ering from osneous cachexia, any violence, or even the slightest. Fig. 3.—Pig suffering fi'oni osseous cachexia (fourth stage). muscular effort may be followed by fracture of the gravest character, involving even the vertebral column. In cows the pelvis, femur, and tibia are most frequently injured. In horses, particularly in riding horses, fractures are commonest in the region of the forearm, cannon bone, and anterior phalanges. So extremely fragile are the bones at this stage that the horse represented herewith broke twelve ribs at one time by simply falling on its side. It is interesting to note that such fractures are never accompanied by any extensive l)leeding. They have little tendency to repair, no real callus formation occurs, and on post-mortem examination one often fiiuls the ends unconnected by temporary callus, worn, and rounded by reciprocal friction. At this stage but under other circumstances, the animals show great reluctance to rise, remaining down for twelve to twenty-four hours without shifting their position. If forced to get up, they stand as though fixed in one position, the respiration and circulation become rapid, and they soon grow tired and fall,.
