548 SPOEADIC DISEASES. 



jind Mr. ]\Ia'!iony, V.S., Templemore, in a letter to me, December 

 1878, describes a well-marked case. I have also seen it in the 

 cow and in the dog. 



M. Girard, Jun., has left a case on record, quoted by Mr: 

 Percivall, which bears out many points in the physiology of the 

 cord already referred to. He says — " The sensibility of the left 

 — the affected — side proved extremely acute. The lips and alee 

 of tlie nose were drawn to the right side, the contrary to that to 

 which the head and neck turned. The occlusion of the nostrils 

 was such that the air made a blowing noise in its passage 

 through them. The left ear was palsied, and the tongue slightly 

 distorted. The lips and nostrils retained their sensibility, though 

 in a diminished degree to what it was on the unaffected side. 

 Wlien oats were laid before the horse, it seized them with the 

 right side of the mouth, the left remaining motionless. It 

 experienced a great difficulty in mastication, and succeeded 

 only in swallowing a part of its food, the remainder staying 

 behind, lodged between the cheek and molar teeth. It could 

 manage to pick up its oats from a plain surface, and when pre- 

 sented to it in a trough, it plunged its muzzle into the 

 middle of them, opening wide its mouth. It could drink but 

 slowly, and with difficulty, and only by thrusting its mouth 

 deeply into the water. The nostril of the affected side perceived 

 scents. It could walk, but could hardly sustain itself after 

 but a short exercise. If attempted to be turned to the left side, 

 this instability became still more manifest. Pressure upon the 

 vertebral column from tlie head to the tail seemed to give great 

 pain. The respiration, althougli sonorous, was regular. On the 

 fourth day, the animal, unable any longer to stand, sank down, 

 and after several turns and ineffectual struggles to rise, rolled 

 over and lay upon its right side. Its bowels were relieved by 

 manual operation, its bladder with the catheter; though even 

 after this it passed its dung, but could not posture itself to 

 pass its urine. Its pulse, like respiration, remained undisturbed. 

 It died on the seventh day." 



In the case of the cow the attack was of an acute kind. The 

 animal was grazing in a fiehl with a lot of otliers, and was left 

 quite well at milking time in the morning. The field being 

 some distance from the house, it was not seen again before 

 evening. It was then found prostrate on the ground, lying 

 upon its left side, and was unable to rise.
