PARALYSIS. 549 



When I saw it I observed the following symptoms: — The 

 left ear was pendulous, left eyelid drooping and closed, the eye 

 squinted outwards. The left lip hung down, the angle of the 

 mouth w-as lower than on the opposite side, the muscles were 

 loose and flaccid, and the lips drawn to the right side. The 

 tongue protruded, and when put into the mouth was drawn to 

 the right side. The neck was twisted and the head drawn to the 

 left side. Deglutition was imperfect, but the breathing was not 

 appreciably affected. The superficial blood-vessels of the right 

 side were engorged with blood, and stood out prominently all 

 over the trunk and neck. The same side was warm, whilst the 

 opposite side was cold, and the hair was " pen-feathered." 



In endeavouring to place the animal on a hurdle for the 

 purpose of removing it to a shed, it was observed that it 

 rolled over from the left to the right side, on which side only 

 could it be made to lie. The bowels were constipated, and the 

 belly tympanitic, the sphincter ani was rather relaxed, the vulva 

 flaccid, and vagina protruding. The animal was quite conscious, 

 but inclined to somnolency. It was bled, a purgative adminis- 

 tered, and the back was fomented and dressed with strong 

 ammonia liniment. On the following morning it was able to 

 rise, but both the legs of the right side remained partially para- 

 lyzed for some weeks. The affection of the face, however, passed 

 away diiring the first night, and it was able to partake of food 

 on the following morning. 



This was a case of hemiplegia due to some ephemeral disease 

 of one side — the left — of the brain ; and from the fact of the 

 outward squinting, amaurosis, and drooping of the upper eye- 

 lid, the conclusion is, the functions of the third nerve being 

 interfered with, that the brain disease — ephemeral as it was — 

 involved the posterior part of the left crus cerebri. It must be 

 remembered that, in all cases of disease affecting one side of 

 the brain, the paralysis is on the opposite side of the neck and 

 trunk, but on the same side of the face. It was remarkable 

 however, in this case, that although the loss of motor power was 

 complete, sensibility remained intact. 



Paralysis from blooi poisoning is witnessed in azoturia, lead 

 poisoning, canine distemper, and grass staggers. In the human 

 being, as well as in horses, cattle, and birds, a form of paralysis 

 arises from the use of the vetch known as the Lathyrus saiivus.
