DISEASES OF THE NERVOUS SYSTEM. 255 



Tteatmenf. — Apply ice or cold water to the head, give injec- 

 tions of turpentine and oil, a strong purgative (horse, aloes and 

 croton ; sheep, ox, Glauber salts and croton ; pig, croton beans), 

 with chloral- hydrate and ergot; bleed from the temporal artery 

 and jugular vein, and follow up with diuretics and sedatives 

 (nitre, bromide of potassium). The animal should be kept in a 

 cool airy stall. If paralysis follows, treat as for that disease. 



INFLAMMATION OF THE SPINAL CORD. MYELITIS. 

 ' SPINAL MENINGITIS. 



The causes are similar to tiiose of phrenitis. The disease 

 may show itself by paroxysms of convulsions, with exalted 

 temperature, increased circulation, and rapid breathing, finally 

 merging into paralysis ; or it may be manifested at once by 

 palsy without previous spasms, but with coldness, and usually 

 dryness, of the paralysed part, though the anterior part of the 

 body may be bathed in perspiration. There may be tenderness 

 on striking the spines in the affected region of the back, and 

 there is great pain and unsteadiness in any attempt at movement 

 even though the patient may be able to stand. There is no 

 redness of the urine as in azotcetnia. 



Treatment. — Apply cold water or ice to the affected part of 

 the spine ; cup or leech, if this can be done ; purge as in 

 plireniti!^, adding ergot of rye or chloral-hydrate. As improve- 

 ment sets in blister the back (cantharides, mustard, etc.), and 

 give diuretics, chloral hydrate, bromide of potassium, ergot of 

 rye. Care must be taken to turn the patient often if unable to 

 stand, giving a soft dry bed, and to draw off the water frequently 

 with a catheter unless it is passed spontaneously. 



EPIDEMIC CEREBROSPINAL MENIGITIS. CEREBRO-SPINAL 



FEVER. 



Inflammation of the substance and coverings of the brain 

 and spinal cord in horses, sometimes prevailing widely in stables
