is often not full of fine detail, withoutwhich no opinion on bone disease can be formed. In the same way a screenexamination will show a fracture, but an opinion of the bone conditioncannot be formed from it. The most usual conditions predisposing to frac-ture are : (1) Atrophy of bone. This may be senile, or due to disease, e.g. anky-losis of a joint or certain nervous affections. (2) Fragilitas ossium. This consists in an inherited tendency tospontaneous fracture, occurring in children and adults. (3) Bone disease, such as tuberculosis, rickets, syphilis, osteo-malacia. (4) Local bone disease or tumours, such as sarcoma, secondary car-cinoma. A condition which frequently leads to fracture is a cystic disease ofbone. Many examples have been shown of late years occurring in the longbones, the humerus being a common seat of this tumour. It is frequentlya very slow form of myeloid sarcoma. Elmslie has drawn attention to thiscystic disease of bone, and shown several interesting examples.
