CLINICAL VETERINARY MEDICINE AND SURGERY. 



By forcing the knee backwards, and thus straightening the leg, the 

 animal was enabled to take one step with the sound limb ; but imme- 

 diately the knee of the injured limb became in the least degree bent 

 the leg collapsed, and the animal nearly fell. Progress was facilitated 

 by pulling forward the lame leg as far as possible, and 

 then pressing on the knee until a step had been taken 

 with the sound leg. The most marked symptoms 

 were absolute inability to advance the leg, and great 

 difficulty in keeping it perpendicular. No fracture of 

 any of the leg bones could be distinguished. Crepitus 

 was entirely absent. 



Diagnosis. — Fractured first rib. 



Prognosis. — Unfavourable so far as useful recovery 

 was concerned. 



Treatment. — Slinging and rest. 



During the three weeks and three days the animal 

 was kept the limb was always flexed and turned 

 slightly inwards, so that the outside toe of the foot 

 became worn. 



Post-niorteni examination showed fractured first rib 

 (see Fig. 36) ; the surrounding muscles were not lace- 

 rated or ruptured. Only a small provisional callus 

 had formed. The broken and overlapped pieces of 

 bone were freely moveable, and not (as might appear 

 from inspection of the figure) rigidly fixed together.

MYOMA OF THE CESOPHAGUS. 



62. A fifteen-year-old gelding, brought for examina- 

 tion on the 4th January, 1895. 



A fortnight before a considerable swelling had been 

 noticed in the lower portion of the jugular furrow, 

 which the owner thought due to collar pressure. 



During the following days the animal began to 

 roar as soon as put to work. The respiration became 

 very rapid and gasping, so that asph3'xia appeared 

 imminent. When swallowing the food passed slowly 

 through the swollen region and showed a tendency to stop. At certain 

 times a part of the liquid taken was rejected through the nostrils. 



On trotting the animal almost immediately began to roar, and the 

 swelling in the jugular region increased, dilating and contracting 

 synchronously with the respiratory movements. 



Diagnosis. — Tumour developed around and compressing the oeso- 

 phagus and trachea, or the nerves in this region. 



The lesion being principally thoracic no useful intervention seemed 

 possible, and the animal was slaughtered. 



Autopsy. — In the lower third of the neck the oesophagus was dilated. 

 Its thoracic portion was very large, firm, and hard, forming a kind of 

 elongated, fusiform tumour, eighteen inches in length and ten in
