PRECIPITATED CALCIUM PHOSPHATE 137 



disease. Enemata of lime water destroy pin worms. . Solution of lime is 

 one of the best remedies in the treatment of vomiting in dogs. It is a 

 direct sedative to the stomach, andj mixed with milk, equal volumes, pre- 

 vents the rapid coagulation of the casein, lessens the formation of large, 

 tough curds in the stomach, and assists the retention and digestion of milk. 

 Syrup of lime is twenty-four times stronger in calcium hydrate than lime 

 water, and is more astringent. It may be given to foals and calves suf- 

 fering from indigestion and diarrhea. It should be administered in a 

 considerable quantity of milk. 



Lime water may be given as an antidote in poisoning by acids. Car- 

 ron oil is a good, mild laxative and antacid for horses with "heaves." 

 It is given on the food. Furthermore, it is an excellent purgative for 

 foals and calves in the treatment of diarrhea and indigestion.

Calcium Phosphate. 



Action and Uses. — Calcium salts are most important constituents of 

 the body, being essential for the contractility of muscles, the activity of 

 nerves, the coagulability of blood and, as calcium phosphate, forming 60 

 per cent, of bones. Calcium is not only necessary for the growth of bone, 

 but also of soft tissues, about 15 grains being required daily by the human 

 adult. Green vegetables, water, eggs and milk are the chief sources of 

 supply. Milk contains more lime than does lime water (0.17%), and 

 much more than meats. The reserve of calcium in the body is in the 

 bones which keep the blood supplied. Much larger quantities of lime 

 are lost in sickness, debility and starvation than in health by the feces 

 and urine — four times as much in the former. Calcium salts mostly pass 

 unchanged through the bowels. A small amount is absorbed and elimi- 

 nated by the large bowel and by the kidneys. The food ordinarily con- 

 tains an amount of lime in excess of the needs of the body. By with- 

 holding lime from the food animals may develop conditions similar to 

 rickets. 



Rickets, however, is not usually due to lack of lime salts, but to an
