230 Diseases of Bone, 



On the subcutaneous surface there is a sharply defined 

 elevated node, the surface of which, as well as of some of the 

 bone near it, is opened out and porous. At a little distance 

 from the node there are some periosteal outgrowths which have 

 a smooth surface. Probably an ulcer of the soft parts has been 

 present over the porous surface. This specimen was formerly 

 classified as a venereal node. B, C. i. 5. M. 15. 



6. 70. Bony Outgrowths on the Tibia, associated with 



Chronic Ulcer of the Leg". — Section of a tibia, injected, 

 and the soft parts, except the periosteum, cleaned off and dried, 

 to show the above. 



The surface of the bone is irregular, and has probably lain 

 beneath an old-standing ulcer. The section shows that the com- 

 pact tissue has been dense and even ivory-like in consistence.

6.71. Bony Outgrowth on the Tibia, associated with 

 Chronic Ulcer of the Leg. — Portion of a left tibia — 

 macerated, to show the above. 



The bone is thickened on the surface, this being probably 

 due to an ulcer of the soft parts over it.

72. Bony Outgrowths on the Tibia, associated with 



Chronic Ulcer of the Leg. — Upper end of a left tibia — 

 macerated, to show the above. 



The bone is very light. There is considerable periostitic 

 outgrowth on the surface corresponding to the origin of the 

 soleus muscle. This condition was probably due to an ulcer oa 

 the soft parts, lower down on the leg. B. C. ir. M. 30.
