the metatarsal bone of a great toe — raacerated, illustrating the 

 above. 



It is rarefied and partially absorbed, and, as it is said 

 to have been spontaneously separated, it has probably been a 

 sequestrum due to tubercular disease. G. C. 1174. 



Presented by Professor James Russell. 



5. Where the Inflammation has heen chie to the combined action 

 of the tubercle bacillus and of pus-forminrj organisms. 



6. 229. Tubercular and Septic Disease of Ulna.— Upper end 



of a left ulna — macerated, illustrating the above. 



The articular surface is opened out, and there is periosteal 

 new bone formation on the shaft. Probably tubercular disease 

 of the synovial membrane of the elbow had spread over the 

 articular surface, and had afterwards become septic from the 

 bursting of an abscess. W. C. G. 58. 



6. 230. Tubercular and Septic Disease of Femur.— Lower 



end of the shaft of a right femur, the epiphysis Avanting — 

 macerated, illustrating the above. 

 Amputation was performed, probably for tubercular disease of the joint. 



The lower end shows the lightening which often occurs 

 near tubercular disease of joints. Some new periosteal bone 

 has been thrown out on the side and back of the shaft.

6. 231. Tubercular and Septic Disease of Femur.— Left 



femur — macerated, illustrating the above. 



From a churchyard. 



There is great incrustation of new bone on the surface, 

 with apparently tubercular disease of the lower articular end. 

 The trochlear surface is rough, and is eaten out as if by
