192 inorganic' agents 



It may be employed to advantage in coryza and ozena, by 

 insufflation into the nostrils. Dermatol (bismuth subgal- 

 late) is even more efficient than the subnitrate alone as an 

 antiseptic and astringent dusting powder. 



Internal. — Bismuth is one of the best agents to relieve 

 vomiting in dogs, owing to the soothing and sedative effect 

 upon inflamed mucous membranes. It may be given alone or 

 in combination with oxalate of cerium upon the tongue or in 

 the food. It is also a very efficient agent in diarrhea in the dog, 

 being astringent, sedative and antiseptic. Its use should be 

 preceded by the administration of oil or calomel, in diarrhoea. 

 Bismuth is given for diarrhoea in powder with salol ; or in 

 suspension with gum arable and water, with one drop of 

 carbolic acid to each dose of bismuth ; or better, in capsules, 

 dispensing one grain of carbolic acid and five grains of 

 bismuth. The sedative effect upon the stomach is increased 

 by giving the subcarbonate of bismuth with bicarbonate of 

 sodium, while the sedative effect upon the bowels is 

 enhanced by combining morphine with bismuth subnitrate. 

 It is generally immaterial whether the subnitrate or sub- 

 carbonate of bismuth be selected in any given case. 

 Bismuth salicylate is more powerful as an antiseptic than 

 the other salts. It is useful in diarrhoea, intestinal fer- 

 mentation and indigestion of dogs. The drug should be 

 given in capsules.
