228 INORGANIC AGENTS 



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 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 dogs may 

 be allayed by the bromides. The bromides are occasionally 

 of value in reflex cough, iialpitation 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.

 Fr.; jod., G. 



Derivation.— lodimQ is a non-metallic element, existing 

 in combination in the animal, vegetable and mineral king- 

 doms. It occurs in seaweed, from which it is obtained by 

 distillation. It is also mined in the form of iodates and 

 iodides. 



Properties. — Iodine occurs in heavy, bluish-black, dry 

 and friable rhombic plates, having a metallic lustre, a 

 distinctive odor, and sharp, acid taste. It is soluble in 

 5,000 parts of water, and in 10 parts of alcohol ; very 

 soluble in ether and in solutions of potassium iodide. 

 Iodine volatilizes on heating, with the formation of a
