thorough agitation, the mixture is allowed to stand 

 from one-half to one hour. For sputum, an amount 

 equal to the volume of the sputum should be added, or 

 the sputum cup should be filled about one-half with the 

 solution before use. Chlorinated lime cannot be used 

 for the disinfection of fabrics or colored goods, since it 

 bleaches and attacks the fabric directly. The chlorin- 

 ated lime used in the preparation of disinfecting solu- 

 tions must have been contained in an air-tight receptacle, 

 otherwise from exposure to the air much of its disin- 

 fecting powers are lost. It has about the same germi- 

 cidal value as milk of lime.
