CALCIUM. CAMPHORA. 21 



CALCIUM. 



A number of lime salts are official, though none of them has any extended utility. 

 Properties: 



Calcium Bromide owes its chief activity to the bromine elements. The Precipi- 

 tated Carbonate, like the other official carbonate, Prepared Chalk, was formerly of 

 considerable repute in the treatment of infantile diarrheas, but is now used chiefly in 

 dentifrices. Calcium Chloride is too harsh for internal use, even if any known indica- 

 tion existed. The Glycerophosphate and Hypophosphite are practically inert, and 

 should be discarded. The Lactate is the preferable salt, if a definite indication for lime 

 arises. The Sulphide is a crude cosmetic preparation. Chlorinated Lime is a popular 

 and moderately efficient deodorant disinfectant. The Oxide, in the form of liquor cal- 

 cis, is frequently recommended as an antacid to be added to cow's milk in infant feed- 

 ing, though cow's milk normally has more lime than human milk, in which case prob- 

 ably sodium bicarbonate would be a preferable antacid. 



CAMPHORA.
