130 Uses of Chlorides and Chlorine. 



newly painted, and carefully closed. The chlorine emanating fFom 

 the chloride from the decomposing action of the carbonic acid of 

 the atmosphere will spread through the apartments and neutralize the 

 odor of the paint. 



If it be desirable also to remove the dampness of the apartment, a 

 few pieces of chloride of calcium, (or muriate of lime,) placed, in 

 earthen dishes in the room, will answer the purpose. 



It is wrong, in such a case, to use fresh lime, along with the chlo- 

 ride, because tlie latter is efiectual only in proportion as the chlorine 

 is disengaged by the action of the carbonic acid and moisture of the 

 air, and the presence of quick lime only serves to attract the same 

 things, and therefore to retard the decomposition of the chloride. 



The same purpose, as it regards odor, may be effected by the 

 separation of chlorine gas, by placing an earthen cup, containing an 

 ounce of oxide of manganese and three ounces of hydrochloric 

 (muriatic) acid, on a hot brick, or over a furnace with a few live 

 coals, or in a vessel of hot water, stirring the materials, and closing 

 the apartment for twenty four hours. 



By heating in the same manner chloride of lime, dissolved in or 

 mixed with water sharpened with sulphuric acid, the same purpose 

 is effected. 



2. The use of chloride in correcting the unhealthiness of manufac- 

 tories of cat-gut, or o\hev fabrics from animal materials. 



Manufactories of this nature are apt to emit a highly disagreeable 

 odor. The free use of chlorine, liberated in the way above indica- 

 ted, will effectually correct the unhealthy emanations. 



3. In disinfecting the mud andfdih of seivers. 



Agreeably to the experimental investigations of a committee cho- 

 sen by the police, it appears that it would require 576 grammes of 

 dry chloride of lime to disinfect one cubic foot of semi-fluid mud, 

 weighing 10 kilogrammes, or 620 grammes of chloride, one foot of 

 more solid filth weighing 10 kilogrammes 50 decagrammes. 



The expense, therefore, deduced from these data, of disinfecting 

 sewers which have become very foul, is considered to be too great, 

 even at the reduced price of chloride of lime, and they therefore 

 prefer the purification by ventilation through the agency of fire. 



4. In disinfecting the air of rooms in which silk ivorms are kept. 

 The experiments of M. Bonafous, very carefully conducted, have 



proved that silk worms, exposed to the putrid exhalations of their 

 litter and excrements, to the odor of dead worms, Sic. will be injur-
