The justification for reporting these three cases lies chiefly in Case 3, which is unusual in the following respects: the marked deformity of the right lower leg, the skin condition (scleroderma), and the fractures of the left forearm, which show non-union roentgenologically after twenty years. The last fact proves that she had some disturbance of bone metabolism many years without much inconvenience.
I desire to express my thanks to Dr. John Lincoln Porter for the privilege of reporting these cases; to Dr. D. B. Phemister for confirming the diagnosis of Case 3, and to Dr. E. L. Jenkinson, roentgenologist at St. Luke's Hospital.
