of epilepsy. Most frequently very quiet, and even dull, it 
was seized, whenever it went out of doors, with convulsive 
movements, and lay for some minutes before it got up 
again. It was treated for cerebral congestion, with com- 
mencing ventricula effusion, which is not uncommon in 
young dogs affected with convulsions. 
Notwithstanding the treatment the symptoms became 
aggravated, and were as follows: Convulsions without any 
assignable cause, grinding of the teeth and champing of the 
jaws, foaming at the mouth, and struggling when lying on 
the ground. There was a marked and increasing tendency 
to turn to the left ; the coma became more urgent, and the 
animal appeared quite torpid, though its appetite was un- 
diminished. It was kept until December, when, its recovery 
appearing hopeless it was killed. A necroscopical exami- 
nation showed that all the abdominal organs were healthy, 
with the exception of the liver and pancreas, on the surface 
of which were observed transparent vesicles similar to those 
of the pig-measle. The liver had two of these on its right 
lobe ; they were about the size of a large pea, lay beneath - 
the peritoneum, and had made a depression in the organ. 
Those on the pancreas were five in number ; they were on 
its upper border, but had not affected the structure of the 
gland. The thoracic organs were healthy. On opening 
the cranium the meningeal membranes were found to be 
very congested ; in the upper and lateral parts of the right 
lobe of the cerebrum were four elevations, corresponding 
to four hydatid cysts, covered by the arachnoid, and lying 
in depressions in the cerebral tissue ; in the left lobe only 
one was discovered. The hydatids were carefully 
examined by M. Mégnin, a veterinary surgeon who has 
made helminthology a special study, and they proved to be 
identical with those of the pig-measle. 
The dog had doubtless obtained the ova from eating 
human excrement, as this animal is sometimes apt to do.
