C. Disinfection by Chloride of Lime. Chloride of c. Disinfection 



by chloride ot 



lime, or bleaching powder, is the most powerful, the lime. General 

 cheapest and most easily managed of all artificial dis- 

 infectants. It can be had everywhere, and at any 

 time, and in quantities sufficient for every purpose. 

 It should as much as possible be applied in solution, 

 of a strength varying somewhat with the particular 

 purpose for which it is to be employed ; and after it 

 has been allowed to act upon the surface or matter to 

 be disinfected a reasonable time, should be washed off, 

 together with all products of decomposition. As 

 chloride of lime does not destroy only the infectious 

 matter in a mixture, but destroys all organic matter 

 without distinction, it is not applicable to large quan- 

 tities of matter, such as the manure of cattle, dung- 

 heaps, &c., inasmuch as twice or three times the weight 

 of these matters of chloride of lime would be required 

 for their effectual destruction and disinfection. It is 

 further inapplicable to all matters rich in ammonia, 

 particularly putrid urine, as it destroys the ammonia 

 and evolves a large amount of gases, some of which 

 have a repugnant odour, and are perhaps not quite in- 

 nocuous. But for the disinfection of surfaces of things 

 and places no better or more suitable agent than 

 chloride of lime is at present known to science.
