Tubercular Caries. 281 



negro, with portion of overlying skin — in spirit, to illustrate 

 the above. 



A sinus shown in the skin communicated " with a vomica 

 of the lungs." The bone seems to have been greatly destroyed 

 and to have been replaced by granulations. 



B. C. I. 5. M. 10. 



6. 204. Tubercular Disease of the Sternum.— Sternum- 

 macerated, illustrating the above. 



The manubrium and lower portion of the body is exten- 

 sively absorbed and opened out, apparently by tubercular 

 inflammation. B. C. i. 5. M. 11. 



6. 205. Tubercular Disease of the Sternum.— Manubrium 



and part of the body of a sternum — macerated, illustrating 

 the above. 



An abscess, probably tubercular, "had formed beneath the 

 sternum." 



The bone is lightened and partially absorbed, especially 

 at the posterior and right margins. G. C. 656. 



6. 206. Tubercular Disease of the Clavicle.— Left clavicle — 



macerated, illustrating the above. 



Tliere is a large irregular erosion on the upper surface, 

 about the middle. The walls of this excavation are rarefied, 

 and the bone in front is reduced to a mere perforated shell. 

 There is comparatively little new bone formation round this 

 eaten-out part, but at the outer end of the clavicle some may 

 be observed. Probably this has been a case of tubercular dis- 

 ease. W. C. G. 26. 



6. 207. Tubercular Disease of Radius and Ulna.— Eight 



radius and ulna — macerated, illustrating the above.
