Prognosis. — When the haemorrhage is extensive, it 

 generally proves fatal. In less severe cases recovery may 

 take place, but more or less impairment of voluntary 

 motion may remain. 



Morbid Anatomy. — Cerebral haemorrhage in the horse 

 occurs in the substance of the brain, but it may also occur 

 in the meninges, especially when due to injury. When thie 

 hsemorrhage is recent, a red clot of variable size is found. 

 This afterwards becomes encysted, and undergoes changes 

 in colour and consistence, and hsematoidin crystals and 

 granular pigment are often found in it. 



In other instances inflammatory changes, resulting in the 

 softening of the cerebral structures, or abscess maybe formed. 



In old horses, the cerebral arteries will probably be found 

 to be in an atheromatous condition. 



Treatment. — In those instances of cerebral hsemorrhage 

 where the coma is attended by full strong cardiac action 

 in the young and previously healthy animal, bleeding is 

 recommended. 



In other cases, all that can be done is to apply cold to 

 the head, which should be elevated a little to allow a good 

 supply of fresh air, and to bandage the legs. If collapse 

 should threaten, owing to intensity of the shock, stimulants 

 may be administered through enemata. In all cases the 

 bowels should be freely acted upon.

 DISEASES OF THE SPINAL CORD. 



INFLAMMATION OF THE SPINAL CORD AND 

 ITS MEMBRANES. — Inflammation of the spinal cord 

 (myelitis), and of its coverings (spinal meningitis), may be 

 described together, as in many instances both the cord and
