CALCIUM CARBONATE 125 



Administration. — Calcium carbonate may be given to dogs in troches, 

 pills or powder; to other animals in powder, balls or electuary. Chalk 

 is commonly prescribed suspended in flour gruel, milk or mucilage to the 

 larger animals. The official preparations are suitable for dogs. 



Uses. — Chalk forms a dusting powder for moist eczema, slight burns 

 and intertrigo, zinc oxide and starch (1 to 4) is, however, a better prep- 

 aration. Chalk is the most useful antacid for diarrhea accompanied by 

 fermentation of the intestinal contents, while its local astringent and pro- 

 tecting influence assist in overcoming the trouble. It is especially good 

 for foals and calves given in flour gruel, and often combined with catechu, 

 ginger and opium.

 smaller patients.
