hylosis usually shows under the raysas a continuity of osseous structure that is unmistakable. Onthe other hand, fibrous union, as we have seen, is inferred fromthe negative evidence of a light interval between the articularsurfaces. Dr. Joachimsthal, of Berlin, f mentions a case in whicha boy of sixteen had the knee excised. The site of the operationwas examined by the Eontgen method eighteen years later, whenthe bones of the leg and thigh were seen to be welded togetherinto one solid bone, bent at an obtuse angle. The compact tissueat the edges and the bars of the cancellous tissue both showed aperfect continuity. This adaptation afforded a good example ofthe change of structure and form that may follow altered function. New growths in the substance of bone may at times be photo-graphed by the Eontgen rays. The first case of the kind wasrecorded by Konig, who found a bright spot, with dark contour, * Paris These, No. 53, D. 23, Louis Laurent,t Therapeutische Monats., February, 1897.

Since that time many sarcomata of bone, central andotherwise, have been reported, some of them accompanied withfracture. Dr. Eichardson of Philadelphia says that by the aid of thefiuoroscope he has been able to watch the growth of an osteo-sarcoma of the radius from day to day. His case is thus de-scribed : General W , aged fifty-nine, had suffered for twelve months from a painful swelling of the right wrist. By means of thefiuoroscope, the ulna was seen to be intact, the radius to ter-minate abruptly in the faint shadow of a carpal tumour. A thinshell of the radius could be seen remaining. The diagnosis ofosteo-sarcoma of the radius, made from the history of the caseand from inspection and digital examination, was practic
