in human practice. Moreover, their use is limited mainly 

 to canine disorders, as bromides have little influence upon 

 diseases of horses. 



Bromides are especially indicated in irritation of the 

 motor area of the cerebral cortex (convulsions), in general 

 nervous excitability, and in corditions due to exalted reflex 

 nervous excitabilty, in cerebritis, and in conditions due to 

 exalted reflex action in dogs. 



The bromides are indeed the best agents we can use to 

 cure fits or convulsions in dogs. They should be combined 

 with chloral and given, if necessary, per rectum. The 

 bromides are useful in canine chorea, in connection with 

 Fowler's Solution. "With chloral the bromides are antidotes 

 to strychnine poisoning. Sexual excitement in all animals 

 may be allayed by the bromides. The bromides are occa- 

 sionally of value in reflex cough, palpitation of the heart, 

 and asthma, but are inferior to other agents in these 

 disorders. 



Potassium bromide is recommended in the treatment of 

 tetanus of the horse, but opium, belladona and cannabis 

 indica are generally more effectual. If the bromides are 

 used they should be given with chloral.
