558. After-effects. 



In some cases partial dulness and ey.en paralysis remain, and con- 

 vulsions may supervene, and in some cases amaurosis. Blisters and 

 setons may be tried ; but as a general rule under such circumstances the 

 best plan is to shoot the animal. 



559. APOPLEXY. 



Horses are sometimes struck down by apoplexy as by a blow, and lose 

 all sense and power of motion, and death quickly ends the scene. Post- 

 mortem examination often reveals a congested state of the vessels of the 

 brain and its meninges. 



Apoplexy differs from coma and encephalitis in rendering the animal 

 totally unconscious. If relief is obtained, which, however, is rare, the 

 case usually resolves itself into a state of partial coma, more or less 

 intense. 



560. Treatment. 



Bleeding, which was in days past the recognised treatment, in apoplexy, 

 both for men and animals, is now abandoned. 



In all cases of cerebral disease the first measure to be taken is the im- 

 mediate removal of pressure, be it from bridle, bearing-rein, harness, 

 collar, or saddle-girth. Next, ice or the coldest water procurable should 

 be applied to the head and along the spine. 



Contrary to experience gained in the human subject, where spirits 

 are expressly forbidden on account of their depressing after-results, a 

 strong diffusible stimulant, such as whiskey and water, has a marvellously 

 revivifying effect ; and this should be maintained by brisk friction to the 

 ears and extremities.

561. Nature of the disease. 



' Vertigo, more commonly called Megrims, is an affection of the brain, 

 but the nature of the disease is not well understood. By some Veteri- 

 narians it has been defined to be a momentary and passing congestion of 

 the Brain.
