LOCOMOTOR ATAXIA— INCOORDINATION OF MOVEMENT. 



This is cbaracterized by an inability to properly control the move- 

 ment of the limbs. The animal appears usually perfectly healthy, but 

 when he is led out of his stall his legs have a wobbly movement, and 

 he will stumble or stagger, especially in turning. When this is con- 

 fined to the hind parts it may be termed a modified form of paraplegia, 

 but often it may be seen to aflect nearly all the voluntary muscles when 

 they are called into play, and must be attributed to some pressure ex- 

 erted on the base of the brain. 



LOCAL PARALYSIS. 



This is frequently met with in horses. It may affect many parts of 

 the body, even vital organs, and it is very frequently overlooked in 

 diagnosis. 



FACIAL PARALYSIS. 



This is a frequent type of local paralysis, and is due to impairment 

 of function of the motor nerve of the facial muscles, the portio dura. 

 The cause may exist at the base of the brain, compression along its 

 course after it leaves the medulla oblongata, or to a bruise after it 

 spreads out on the great masseter muscle. 



Symptoms. — A flaccid condition of the cheek muscles, pendulous lips, 

 inability to grasp the food, often a slow and weak movement in chew- 

 ing, and difficulty and slowness in drinking. 



LARYNGISMUS PARALYTICUS— ROARING. 



This condition is characterized by roaring, and is usually caused by 

 an inflamed or hypertrophied bronchial gland pressing against the left 

 recurrent laryngeal nerve, which interferes with its conducting power. 

 A similar condition is occasionally induced in acute pleurisy, where the 

 recurrent nerve becomes involved in the diseased process or compressed 

 by plastic exudation. 



PARALYSIS OF THE RECTUM AND TAIL. 



This is generally the result of a blow or fall on the rump, which 

 causes a fracture of the sacrum bone and injury to the nerves supply- 

 ing the tail and part of the rectum and muscles belonging thereto. 

 This fracture would not be suspected, were it not for the loss of motion 

 of the tail. 



INTESTINAL PARALYSIS. 



Characterized by persistent constipation ; frequently the strongest 

 purgatives have no effect whatever on the movement of the bowels. 

 In the absence of symptoms of indigestion, or special diseases impli- 

 cating the intestinal canal, torpor of the bowels must be attributed to
