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. Megnin, 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.
