Necrosis from Pus-forming Organisms. 259 



might have at first caused the enlargement of the fibula, and 

 afterwards extended into it, while its presence would account 

 for the localised destruction of the tibia. G. C. 1482.

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

 Necrosis. — Lower two-thirds of a left tibia — macerated, illus- 

 trating the above. 



This specimen is described in the General Catalogue as belonging 

 to a person aged 14, and in the former printed Catalogue as belonging to 

 an old person. From the general appearance of the specimen, and from 

 the union of the lower epiphysis, the latter statement is evidently the 

 correct one. 



There has been necrosis, apparently, of almost the whole 

 shaft, but the sequestrum, although pitted and eroded, has 

 not been completely separated at the lower end. Along the 

 inner and back part_there has been a development of new bone, 

 which is adherent to portions of the original shaft. 



G. C. 1144. 



6. 133. Acute Suppurative Osteo-myelitis of the Fibula 



— Necrosis. — Lower fourth of a tibia — macerated, illustrating 

 the above. Lower necrosed portion wired to the part above. 



The lower end has necrosed and has been partly absorbed. 

 The vipper portion shows a considerable crust of ncAV periosteal 

 bone on its surface. W. C. G. 61. 



(c.) Sequestra, or portio^is of dead heme which hare been separated from the 

 living by natural 2)roccsses. 



6. 134. Sequestrum, after Acute Suppurative Osteo- 

 myelitis of the Ulna. — Upper three-fourths of an ulna 

 which formed the above. 



The patient was a little Cashmir girl. This piece of bone was 

 removed by Dr. A. Neve in May 1887, after the acute symptoms had 

 subsided. She made an excellent recover}', and had a useful elbow- 

 joint.
