rarer towards the surface ; the}' sprang from the inner aspect of the 

 upper third of the scapula, the point of origin of the tumour. The 

 neighbouring muscles, the ribs, vertebras, and cervical ligament were 

 not invaded. The connective tissue between the subscapular and large 

 serratus muscles contained some secondary tumours. 



The superficial layers of both pulmonary lobes were dotted with 

 nodules, varying in size between a pin's head and a walnut, some 

 blackish and haemorrhagic, others greyish-white, the majority hard and 

 like the primary tumour, containing bone elements. Sections showed 

 many new growths scattered through the two lobes. The mitral and 

 tricuspid valves were irregularl}- thickened by little whitish, very hard 

 nodules. 



Nothing abnormal was discovered in the abdominal organs. 



On microscopic examination the primary and secondary tumours 

 were seen to be formed of polymorphic cells, though round, uni-, or 

 multi-nuclear cells preponderated. At certain points an intermediary 

 fibrillated substance and tracts of osteoid tissue could be detected.

History. — Had gone lame a fortnight before examination. 



State on Exaniination. — Was slightly lame in the near shoulder. The 

 shoulder was bathed with hot water for half an hour three times daily, 

 and a lotion containing belladonna, arnica, and rectified spirit after- 

 wards applied. 



The patient remained in much the same condition for about three 

 weeks, when it suddenly became very lame, dragging its leg behind it 

 in a helpless fashion when made to walk, and evincing the greatest 

 difficulty in passing over the threshold of the stable door, apparently 

 being quite unable to advance the toe of the foot. The same treatment 

 was continued for three or four weeks, at the end of which the swelling 

 pointed and burst, the opening resembling a small punctured wound 

 about half an inch in length. By probing, the scapula could be felt, 

 and a number of sinuses detected burrowing in all directions and filled 

 with pus, which gave off a most offensive odour. The wound was 

 enlarged by an incision about four inches in length above and along 

 the vertebral edge of the scapula. The wound was thoroughly syringed 

 out three times a day with the following :

Aqua pura ....... j^U- 



At the end of six weeks, as the case showed little signs of improve- 

 ment, the wound was opened sufficiently to allow the hand to be 

 inserted behind the bone ; on manipulation the superior portion of the 

 scapula could be distinctly made to move backwards and forwards, 

 giving the impression of the superior third of the bone being broken off 

 from the inferior two thirds. The antiseptic treatment was continued. 

 Abscesses now began to form and discharge on the muscles of the
