6. 462. Sarcoma of the Humerus, following" Fracture. — 



Part of the soft portion of the previous tumour, with adjacent 

 muscles — in spirit. 



"Its tissue is medulliform, interspersed with bony sj)icules 

 and nodules of cartilage." The muscles are being infiltrated all 

 round ; at one place in the interior, the tumour is breaking 

 down. G. C. 335. 



6. 463. Sarcoma invading" the Tibia.— Upper part of the left 



leg of a young man- — in spirit, illustrating the above. 



"This young man was a sailor, and three months before the 

 appearance of the tumour of the leg, he received a blow on the upper part 

 of the shin by the recoil of a gun. He does not attribute the growth of 

 the tumour to this hurt, and it was only by questioning him as to all 

 probable causes that this circumstance was brought to his recollection. 

 The tumour extends from the middle of the tibia to the tendinous 

 insertion of the patella into that bone. It surrounds the tibia and the 

 head of the fibula, and evidently goes round to the back of the bones, for 

 it has distended the gastro-cnemius and the soleus muscles. Its 

 surface is distinguished by seven or eight distinct knobs or tubercles, 

 which are soft or yielding, and give no indication of solidity or of 

 scirrhous hardness. The tubercles on the lower part of the tumour have 

 more firmness and solidity than these above. The surface is of a dark 

 reddish colour ; the centre of the tubercles being of a yellowish colour, 

 but crossed with numerous small veins, which give a venous or purplish- 

 tinge. The tumour has been two months of acquiring its present magni- 

 tude, and is not accompanied with pain. 



" When this young man had been a few days in the Hospital, and 

 when I had ascertained the disease to be that most mortal of tumours, the 

 fungus tumour, called soft cancer, I informed him of his danger. He was 

 surprised that I should consider it so seriously, but threw himself entirely 

 into n. y hands. In these circumstances such confidence only adds to the
