6, 294. Syphilitic Enlargement of the Radius.— Right radius 

 —macerated, illustrating the above. 



There is an irregular thickening of the lower end of the 

 bone, beginning a little above the articular surface, and extend- 

 ing up to the middle. The thickened part is very irregular, 

 partly from eating out of its surface, and partly from the forma 

 tion of new bone. It has the appearance of a node, which had 

 become the seat of destructive changes. W. C. G. 31. 



6. 295. Congfenital Syphilitic Enlarg'ement of the Radius. 



— Plaster cast of the right forearm of a boy, showing a swelling 

 over the upper part of the radius. 



The boy had " Hutchinson's teeth," and ulcerations of the 

 palate and nose. There was a clear history of syphilis in his 

 parents. G. C. 3282. 



6. 296. Syphilitic Enlarg'ement of the Femur.— Upper half 



of a right femur — macerated, illustrating the above. 



There are irregular thickenings all over the shaft. These 

 have been at one or two places the seat of destructive changes. 

 The bone is unduly heavy: B. C. i. 5. M. 57. 



6. 297. Syphilitic Enlarg'ement of the Femur.— Left femur 

 — macerated, illustrating the above. 



On the inner and outer surfaces above there are nodular 

 thickenings, which are continuous with one another on the
