MENINGITIS. 



Meningitis, or inflammation of the coverings (meninges) 

 of the brain, in which those enveloping the spinal cord 

 generally become involved, is occasionally seen in the dog. 

 It is usually associated with epilepsy, especially if the 

 seizures are frequent and protracted. At the present time 

 I have a well marked case under treatment, the subject 

 being an aged colley sh^ep-dog. 



The following were the symptoms presented on my first 

 seeing him : eyes deficient in lustre and somewhat vacant 

 lids frequently closed, head drooped, clonic spasm of the 

 muscles of the lower jaw, the latter repeatedly closing with 

 a sudden click. The animal always lay on the left side ; 

 when walking he inclined the same way ; hurried, reeling 

 locomotion, tongue loaded with fur, nose dry, hot and stuffy, 

 excessive drowsiness with occasional spasmodic twitchings, 

 pulse frequent and small, appetite moderately good, with a 

 preference for liquids. 



I inserted a seton at the back of the head, ordered milk 

 diet, and -prescribed 



Nux Vomica \ grain. 



Quinine Sulph i grain. 



Ferri Sulph 5 grians. 



This was given in a dessert-spoonful of sherry, three times 

 a day. The patient is slightly but daily improving under 

 this treatment, and I have hopes of a recovery. He has 

 now been three weeks ill, and a fortnight under treatment. 

 A slight increase was made in the nux vomica recently.
