6. 126. Acute Suppurative Osteo-myelitis of the Tibia- 

 Necrosis, Ulcer of the Leg". — Portion of a tibia — macerated, 

 illustrating the above. 



A large loose sequestrum near the lower end has been 

 partially surrounded by new bone. Near the upper end of the 

 preparation there is a flattened enlargement, with an irregular 

 and somewhat porous surface. This has probably formed 

 the base of a chronic ulcer of the skin, secondary to the bone 

 disease. B. C. i. 5. M. 34. 



6. 127. Acute Suppurative Osteo-myelitis of the Tibia- 

 Necrosis. — Eight tibia and fibula — injected, muscles removed, 

 and in spirit, illustrating the above. A sequestrum removed 

 from the tibia is fixed by a thread to the fibula. 



A bridge of bone formerly lay over the large newly formed 

 bone cavity, in which the necrosis was lodged. This bridge 

 was cut across by the surgeon in order to extract the necrosis. 

 The vascularity of the new bone is shown by the injection. The 

 disease apparently had extended close to, if not into, the knee- 

 joint. G. C. 1056.

6. 128. Acute Suppurative Osteo-myelitis— Necrosis.— Pre- 

 paration apparently of a tibia, illustrating the above. 



There are two separate sequestra. They are only partially 

 surrounded by a case of new bone, which shows cloacae at some 

 places and irregular gaps and apertures at others.

6. 129. Acute Suppurative Osteo-myelitis of the Tibia- 

 Necrosis. — Lower three-fourths of a left tibia — macerated, 

 illustrating the above.
