abnormal condition in which the lime ingested cannot be deposited in the 

 bones, although abounding in the blood. Lime being deficient in the bones 

 in rickets and osteomalacia, it has been given in these conditions and 

 also in caries and fragilitas ossium. Unless the food has been deficient 

 in calcium salts their use will probably be of little benefit. 



The same comment applies to the administration of calcium salts in 

 delayed union in fractures and in anemia, malnutrition, and weakness 

 of young animals. In the latter conditions the calcium salt should be 

 given with iron. Calcium phosphate should be given on food with iron to 

 improperly nourished pregnant animals and prevents loss of the young 

 through marasmus and rickets. 



Adxninistration. — Precipitated calcium phosphate may be given on 

 the ifoo^, but is morfe- readily absorbed if it is administered in the syrup 

 of calcium lactophosphate. A glycerophosphate of lime has recently come 

 into vogue and preparations are made containing the glycerophosphates 

 of lime, potassium, magnesium, iron, sodium and quinine. They are used 

 in anemia and malnutrition and convalescence. 



Dose, of the glycerophosphate of calcium and iron — H., 3i-ii.; D.,

Calcii CiiLOKiDUsr. Calcium Chloride. CaCl^. 

 (U. S. & B. P.) 



Synonym. — Calcium chloratum, chlorure de calcium, Fr.; chlorcalcium, cal- 

 cium chlorid, G. 



Derivation. — Neutralize hydrochloric acid with calcium carbonate and evapo- 

 rate: 2HCl+CaC03=CaClj4-C02+H20. Fusion at the lowest possible tem- 

 perature renders the salt anhydrous. 



Properties. — White, slightly translucent, hard fragments, granules or sticks; 

 odorless; having a sharp, saline taste, and very deliquescent. Soluble in 1.2 part 

 of water, in about 10 parts of alcohol. 



Dose.—U. & C, Sss-i, (lS-30); D., gr.5-20, (.3-1.3). 



Oelatiiium. Purified Gelatin. (U. S. P.) 



Derivation. — The purified air-dried product of the hydrolysis of certain ani- 

 mal tissues, as skin, ligaments, and bones, by treatment with boiling water. 



Properties. — An amorphous, more or less transparent solid, usually shredded 

 or in thin sheets; colorless or with a slight yellowish tint, inodorous, and having 

 a, slight, characteristic, almost insipid taste. Insoluble in cold water, but swells 

 and softens when immersed in it, gradually absorbing 5 to 10 times its weight of 

 water. Soluble in boiling water and glycerin, insoluble in alcohol, ether and 

 chloroform, fixed and volatile oils. 



Actions and Uses. — Calcium chloride has been used of late exten- 

 sively both to prevent and arrest hemorrhage. Outside of the body, cal- 

 cium chloride causes blood to coagulate more quickly and firmly than 

 usual, and the same kind of action appears to obtain — i.e., rendering 

 blood more coagulable — when the salt is given internally. Calcium 

 chloride is used as a hemostatic in hematemesis, hemoptysis, purpura 

 hemorrhagica and in all conditions giving rise to hemorrhage. When 

 administered by the mouth several days before surgical operations in 

 maximum doses it may lessen hemorrhage in cases likely to be attended 

 by much bleeding. But, if given too long, calcium chloride lessens the 

 coagulability of the blood and thus not more than 6 or 8 doses should be 

 given, 3 times daily. Calcium lactate has the same action- and is less 

 irritating so that it is more suitable for dogs in the same doses, as the
