DISEASES OF THE NERVOUS SYSTEM. 273 



unaer which the effusion had occuri-ed was covered with a 

 soft pulpy mass of pus and recently-exuded fibrin, which also 

 was spread over the surface of the hemisphere. This portion 

 of the brain was somewhat diminished in bulk, but no morbid 

 appearances were observed in its structure ; in the centre of 

 the left corpus striatum a recent lijemorrhagic clot was found. 

 " Under the microscope the exudation was found to con- 

 sist of ordinary inflammatory products, numerous pus cor- 

 puscles, large exudation corpuscles, fat granules, and fine 

 white fibres." 



NEURALGIA. 



Mr. Fleming has kindly given me the following par- 

 ticulars of an interesting case which came under his care : 



" An Irish setter, three or four years old, very fond of the 

 water, which she went into all seasons, summer and winter, 

 was sent to»me for my opinion. Her master complained that 

 at night, and even during the day, she was seized with fits of 

 howling and screaming, and appeared to be suffering most 

 acute pain. I examined the mouth carefully for decayed 

 teeth, the ears for canker, etc., but nothing could be found 

 the matter with her in these respects. When being led away 

 she suddenly gave a piercing howl, bent her head round to 

 the right side, as if suffering from earache or toothache. 

 She gradually rose up on her hind-legs, fell backwards, and 

 lay howling for a considerable time. Another examination 

 was made, but nothing could be discovered to account for the 

 peculiar symptoms. The animal was perfectly conscious 

 throughout. 



"Surmising the case to be one of tic douloureux or 

 neura.lgia, I had a blister applied from the root of the ear 

 along the right side of the face, and a dose of castor-oil ad- 

 ministjered. The symptoms continued for two or three days. 

 Twice a day a little extract of belladonna was rubbed on the 

 blistei[ed surface. In about a week the animal was quite 

 well Jind there has since been no returns of the symptoms."
