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 brought 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

given occasionally, and some improvement appeared to be 
produced, as the animal could, after a time, see with 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
