Physical examination of the bony system showed the following: A slight ridge 

 can be felt extending along the suture lines of the skull. There is a hard nodule 

 about the size of a pea on the temporal bone behind the right ear, an indefinite firm 

 swelling behind the left ear, and three small, firm nodules on the frontal bone. There 

 are two firm swellings on either side of the raphe, between the hard and soft palate. 

 There is a sharp, bony exostosis on the outer side of the outer third of the right 

 clavicle. There is a marked rosary. At the left, over the costochondral margin, there 

 is tender elevation. There is moderate kyphosis of the cervical and upper dorsal verte- 

 brae and marked scoliosis. The sacrum is very prominent." The iliac wings are thick-

ened and nodular. The left leg is somewhat longer than the right, owing to bowing 

 out of the right femur, just above the middle (the site of the old fracture, over which 

 is a large callus). The surfaces of both shins are roughened. Just below the middle 

 of the left tibia, and involving chiefly the inner surface, is a hard, oval, bony mass 11 

 cm. long and 13 cm. wide. On the second metacarpal joints of both hands, there are 

 hard swellings. These bony masses and nodules are not tender.

 the skeleton. 



Osteomata and calcification of various tissues are not uncommon oc- 

 currences. Buerger and Oppenheim have pointed out that hetero- 

 plastic bone formation in the dura, pia, arachnoid, muscles, bladder, scars,
