CALCIUM CHLORIDE 211 



Chlorinated lime, in powder or in 10 per cent, solution, is 

 spread about cow-houses and premises where contagious or 

 epizootic diseases prevail. When free and rapid evolution of 

 the hypochlorous and chlorine gases is desired, vessels con- 

 taining the powder are set about, and sulphuric acid poured 

 over them ; a more gradual evolution is effected when cloths 

 saturated with a strong solution are suspended inside the 

 infected dwellings. Solutions varying from one to ten per 

 cent, are employed for disinfecting hides, flesh, or excreta of 

 diseased animals. It has the disadvantage of a sickly smell, 

 which is disliked both by horses and cattle ; it is gradually 

 converted into calcium chloride, which, having great affinity 

 for water, leaves the floors, walls, and other surfaces to which 

 the deodoriser has been applied in a very moist state ; while 

 its property of decomposing ammonia, urea, and such other 

 unstable nitrogen compounds, greatly diminishes the agricul- 

 tural value of any manure to which it is added. Scattered 

 about stables or cow-houses, it drives away flies ; while 

 neither rats nor mice frequent places where it is sprinkled, 

 especially when mixed with sulphur.

CALCIUM CHLOEIDE. CALCII CHLORIDUM. CaCl 2 2H 2 O. 



Chloride of calcium, the salt formed by neutralising 

 hydrochloric acid with calcium carbonate, carefully desic- 

 cated at a temperature not exceeding 392 Fahr. (B.P.). 

 It occurs in white odourless scales or masses, with a saline 

 taste ; deliquescent ; soluble in an equal weight of water, 

 and in three parts alcohol. Calcium chloride is believed to 

 increase the coagulability of the blood and is sometimes 

 administered as a haemostatic in haemorrhage from the lungs, 

 or stomach, and, with or without addition of sterilised 

 solution .of gelatin, a few days before operations in which 

 bleeding may be profuse. It is also employed externally as a 

 styptic.
