SPINAL MENINGITIS. 211 



Paralysis of hearing, of the external ear, of the eyelid, partial 

 paralysis of the heart and organs of respiration, of the blood vessels 

 from injury to the vaso-motor nerves of the esophagus, or loss of 

 deglutition, palsy of the stomach, all may be manifested when the 

 supply of nervous influence is impaired or suspended. 



Treatment for paralysis. — In all paralytic affections there may be 

 anesthesia., or impairment of sensibility, in addition to the loss of 

 motion, or there may be hyperesthesia, or increased sensibility, in 

 connection with the loss of motion. These conditions may call for 

 special treatment in addition to that for loss of motion. Where 

 hyperesthesia is well marked local anodynes may be needed to relieve 

 suffering. Chloroform liniment or hypodermic injections of from 

 3 to 5 grains of sulphate of morphia will allay local pain. If there is 

 marked anesthesia, or loss of sensibility, it may become necessary to 

 secure the animal in such a way that ha can not suffer serious 

 injury from accidents which he can not avoid or feel. In the treat- 

 ment of any form of paralysis we must always refer to the cause, and 

 attempt its removal if it can be discovered. In cases where the 

 cause can not be determined we have to rely solely upon a general 

 external and internal treatment. Externally, fly blisters or strong 

 irritant liniments may be ajDplied to the paralyzed parts. In hemi- 

 plegia they should be applied along the bony part of the side of the 

 neck ; in paraplegia, across the loins. In some cases hot-water cloths 

 will be beneficial. Internally, it is well to. administer 1 dram of 

 powdered nux vomica or 2 grains of sulphate of strychnia twice a 

 day until twitching of some of the voluntary muscles occurs; then 

 discontinue it for several days, and then commence again with a 

 smaller dose, gradually increasing it until twitching recurs. Iodide 

 of potash in 1 to 2 dram doses two or three times daily may be em- 

 ployed with the hope that it will favor the absorption of the clot or 

 obstruction to the nervous current. In some cases Fowler's solution 

 of arsenic in teaspoonful doses twice a day in the drinking water 

 proves beneficial. Occasionally benefit may be derived from the 

 application of the electric current, especially in cases of roaring, 

 facial paralysis, paralysis of the eyelid, etc. Nutritious but not 

 too bulky food, good ventilation, clean stabling, moderate exercise 

 if the animal is capable of taking it, good grooming, etc., should 

 be observed in all cases. 



SPINAL MENINGITIS, OR INFLAMMATION OF THE MEMBRANES ENVELOPING 



THE SPINAL CORD. 



Causes. — This may be induced by the irritant properties of blood 

 poisons, exhaustion and exposure, spinal concussion, all forms of 

 injury to the spine, tumors, caries of the vertebra?, rheumatism, etc. 



Symptoms. — A chill may be the precursor, a rise in temperature, or
