end of a humerus and elbow-joint, with tumour and adjacent 

 soft parts attached — injected with carmine and gelatine, and in 

 spirit, illustrating the above. 



The patient was a man, aged 68. The swelling appeared at the 

 back of the arm one year before the operation, and was taken at first for 

 an enlargement of the bursa over the olecranon. The rapid growth, 

 however, soon made its nature apparent, and the arm was amputated. 



The tumour was soft, with small calcareous and osseous 

 deposits scattered throughout it, especially at the margins. It 

 has invaded the bone, and seems to have pushed the muscles 

 and fascia aside rather than infiltrated them. G. C. 2837.

"John Wright, aged 13, was admitted into the Royal Infirmary 

 under Dr Handyside on 13th June 1843, with an extensive tumour of the 

 left thigh-bone. 



"Six years since he had an attack of scarlatina, on recovering 

 from which the left thigh remained weaker than the other, and appeared 

 also to be smaller in size. For this the part had been rubbed frequently 

 with various ointments. He continued to go about, otherwise quite well, 

 till about six montlis ago, when, during the night, he was suddenly seized 

 with violent pain in the thigh. Poultices were next applied to the 

 affected part, and afterwai-ds sinapisms and a few leeches ; but under the 

 treatment the thigh increased rapidly in size. Since then the tumour has 

 gradually increased, and of late he has experienced considerable uneasiness 

 from the frequent pain in it, and the deprivation of sleep thus occasioned. 



"On examination, the thigh was found to be much enlarged, 

 especially at its middle, whence it tapered gradually towards each 

 extremity. The tumour was hard and inelastic, connected evidently 

 with the OS femoris, and it occupied about the three middle fifths of that 

 bone, leaving its extremities of nearly the normal size. Its surface was 

 smooth and regular, and over it the muscles and other soft parts could be 

 moved freely. The integument over the disease presented a somewhat 

 glistening appearance, but was not discoloured ; and beneath it there 

 appeared some faint blue lines, indicating distension of the superficial 

 veins. The tumour was the seat of acute, darting pain, which became
