ENCEPHALITIS. 515 



drachm of calomel for the horse ; twenty ounces of sulphate of 

 magnesia, and fifteen croton beans for a fall-sized ox or cow ; 

 after which the animal is to be kept as ciuiet as possible ; 

 all food must be removed ; plenty of water allowed to drink ; 

 an enema now and then administered ; and the head bathed 

 with cold water. The attendant is to do all this quietly and 

 calmly ; there must be no shouting, or any noise to disturb 

 the animal, nor is it to be continually dosed with medicine. 

 Time must be allowed for the purgative to act, and in some 

 cases there is no response for two or three days ; but if the 

 symptoms abate, no alarm need be felt, aa the bowels are 

 always slow to act when in a paralyzed condition. Should the 

 symptoms increase in severity, belladonna might be tried, in 

 two-drachm doses of the extract, or half-grain of atropine injected 

 subcutaneously. 



I think this form of constipation offers a fair field for the 

 chloride of barium, about ten grains of which might be intra- 

 venously administered to induce rapid action of the bowels. 



Wlien the acute symptoms have passed off, it may be neces- 

 sary to apply blisters to the loins, or at the back of the poll ; 

 but during the earlier stages, more especially if the horse is 

 restless, nothing should be done to irritate and annoy it, or it 

 may work itself into a state of excitement which speedily termi- 

 nates in death. In addition to blisters, I have found the iodide 

 of potassium, given twice a day, to be exceedingly useful in pro- 

 moting the absorption of any exudate or effusion ; and should 

 the bowels remain torpid, and an imperfect paralysis continue, 

 nux vomica may be added with advantage. It may be here 

 remarked that the arrestation of the urinary, biliary, and intes- 

 tinal secretions are results of cerebral disturbance, and that 

 when this is removed the secretions regain their natural con- 

 dition. Purgatives are useful as removers of the cause, which is 

 food containing deleterious principles, and as derivatives. If the 

 pulse be feeble, small doses of stimulants — ammonia — may be 

 administered. I am, however, no advocate for large doses of 

 stimulants, as they tend to excite the animal and make it restless, 

 wlum qiiietude is of the greatest importance.
