6/458. Sarcoma of the Femur, following- Fracture.— 



Section of the loAver end of a right femur — in spirit, illustrating 

 the above. 



In these two last preparations (see series 3. 247) we have instances 

 of a circumstance, which I suspect not to be uncommon, fungus ha-matodes 

 taking place in the bone after fracture of it." (Bell's M.S. Catalogue.) 



The lower end of the upper fragment has projected into the 

 front of the knee-joint, and has pushed down the patella before 

 it. The interval between the broken ends of the bone is 

 occupied partly by fibrous tissue and partly by the tumour 

 substance, now shrivelled and blanched by the spirit so as also 

 to look fibrous. B. C. i. 1. M. 33. b. 



6. 459. Sarcoma of the Humerus, following- Fracture.— 



Section of the upper end of a left humerus — in spirit, illustrat-

From a patient in whom "fungus tumour" formed after fracture. 

 There is a sarcomatous tumour at the broken end, which 

 has grown partly in the medulla and partly under the 

 periosteum. G. C. 335.
