Syphilitic Enlargement. 327 



6. 323. Syphilitic Enlargfement of the Tibia.— Left tibia- 

 macerated, illustrating the above. 



About the middle there is a considerable thickening, the 

 surface of which is smooth behind, but irregular and porous on 

 the inner side, B. C. i. 5. M. 70. 



6. 324. Syphilitic Enlargrement of the Tibia.— Middle third 



of a left tibia — macerated, illustrating the above. 



There is a considerable periosteal thickening on the inner 

 and posterior aspects, and its surface is rough and porous all 

 over. G. C. 1006. 



6. 325. Syphilitic Enlargement of the Tibia.— Left tibia — 



macerated, illustrating the above. 



A churchyard specimen. 



The shaft is encrusted with periosteal bone all over, but 

 especially along the back, and near the lower end of the inner 

 surface, where a node has been developed. The surface of 

 the new bone is partially destroyed, probably from its having 

 been buried. B. C. i. 5. M. 49. 



6. 326. Syphilitic Enlargrement of the Tibia.— Left tibia- 

 macerated, illustrating the above. 



The whole of the bone from the upper third to within an 

 inch of the lower articular surface is thickened by periosteal 

 deposit, especially on the anterior and lateral aspects. The 

 surface of the enlargement is unusually irregular, and at places 

 has been rarefied and eroded. The bone is increased in weight. 



G. C. 1005. 



6. 327. Syphilitic Enlarg-ement of Tibia and Fibula.— 



Lower halves of a right tibia and fibula — macerated, illustrating 

 the above.
