34 PARALYSIS — PALSY. 



fits continued from the 23d to the 27th May, when he died in a convulsive 

 paroxysm. The treatment consisted in blood-letting and purging ; in giving 

 half a drachm of prussic acid in a pint of cold water every four hours. It 

 afforded no relief " On taking off the skin covering the occiput, a sanious 

 discharge escaped, exposing a piece of detached bone, the cavity around be- 

 ing in a state of necrosis. A small sinus extended into the investment of the 

 skuU, with serous effusion and a little pus upon the cerebellum and spinal 

 marrow. The tunics were slightly congested." The whole of the occipital 

 ridge was in a complete state of caries. There was no interposition of sound 

 bone between the diseased part and the cranial cavity. Mr. Youatt — to whom 

 the bone was sent — presented it to the Veterinary College. 



Paralysis Partialis occurs generally in parts about the head. 

 The face is drawn to one side ; the corner of the mouth upward, 

 towards the eye ; and the distortion is evidently occasioned by a 

 loss of power in the antagonist muscles. The masseter muscle 

 has been palsied, and the consequence has been difficulty in mas- 

 tication, causing the horse to cud his food and eject it, instead of 

 swallowing it. Amaurosis is an instance of partial palsy : light 

 cannot be perceived, and yet the eye retains the power of motion. 



A SINGULAR CASE of paralysis, partially involving both the 

 voluntary and excito-motory or involuntary systems, is related in 

 The Veterinarian for 1833, by Mr. Bainbridge, V.S., Saffron 

 Walden. 



A three-year-old colt presented the following symptoms: — Penis drawn, 

 and urine dripping away ; tail depressed, without power to raise it ; faeces 

 lodged in the rectum for want of the power to expel them ; countenance dull ; 

 lips slightly drawn to the left side ; sight impaired, most in the left eye ; 

 mouth hot ; pulse 60, and full ; willing to feed, but has difficulty in taking 

 food into his mouth ; runs his head, mouth open, into the manger, and throws 

 the food from side to side before he is able to get it between his grinders ; 

 that accomplished, he appeared to masticate well. Mr. B. w^as assured the 

 colt had received no injury about the head or otherwise. He had previously 

 been noticed for being dull at pasture, not playing about like other colts, and 

 for not having thriven. He was bled, and took a cathartic, and was put into 

 a loose box. While the physic was operating, there being no voluntary power 

 to void the faeces, they ran from him spontaneously down his tail and legs, as 

 he moved about. He staggered more in his gait than yesterday. Apply a 

 strong blister to the head. Sixth day, much worse : now, after he had seized 

 hold of food, it fell from his lips again, and he had lost all power of mastica- 

 tion. On the tentli day he was destroyed.
