Physiological Action.— The insoluble preparations, as the sub- 

 nitrate and subcarbonate, promote the appetite, increase the diges- 

 tive power, and cause a gain in body weight. They are some- 

 what astringent and retard intestinal movements and produce 

 constipation. As they are insoluble, or nearly so, they pass 

 down the intestinal tract and are converted into sulphides, causing 

 the faeces to become a dark slate color. Toxic symptoms may 

 arise from the adulteration of bismuth with arsenic. They are 

 astringent, antiseptic and sedative to mucous membrane and 

 abraded skin. The subnitrate is the salt chiefly used. It allays 

 irritation in dyspepsia, vomiting, and gastro-intestinal catarrh, or 

 irritation from any cause, by virtue of its medicinal and mechani- 

 cal action. It is used to relieve itching and burning of abraded 

 skin and in skin diseases. For diarrhoea use bismuth and opii 

 combined. Being insoluble bismuth forms a coating over the 

 bowel. 



For itching skin diseases in dogs, the following prescription 

 is recommended :
