282 The Management and Diseases of the Dog. 



upon the head, and in reply he stated that he had reason 

 to believe he had met with some injury in the stable, 

 he thought from one of the horses. The owner had had' 

 the dog examined at Oxford, and afterwards brolight him 

 to London for our opinion. After the. examination we felt 

 satisfied that the dog was suffering from some diseased 

 condition of the brain, and that his loss of vision was due 

 to this cause. It was noticed that the dog was steady 

 and cautious in his movements, turning neither to the right 

 nor to the left, yet he seemed perfectly obedient to his 

 master's call. For the purpose of treatment the dog was 

 removed to our infirmary, and general depletive measures 

 were used at first ; mild doses of aperient medicine were 

 given occasionally, and some improvement appeared to be 

 produced, as the animal could, after a time, see with the

 was a rigid condition of the muscles of the' neck, the 

 pulsation of the heart was feeble, and it was apparent 

 that the animal's end was approaching. He died at five 

 o'clock p.m." 



Post-mortem Examination. — On removing the calvarium 

 it was apparent that effusion had taken place into that 

 part of the arachnoid sac which is reflected over the left 

 hemisphere ; a slight puncture, made by the saw while the 

 bone was being removed, was followed by the forcible 

 expulsion of pus-like fluid. The dura mater was dark-red 

 in colour, and came way from the bone very easily ; the 

 inner surface of the portion under which the effusion had 

 occurred was covered with a soft pulpy mass of pus and
