323. Disinfectants and Deodorizers. 



True disinfectants act chemically by decomposing noxious gases and 

 organic matters. Such are chlorine and its compounds, sulphurous acid, 

 Macdougal's disinfectant, Condy's fluid, chloride of lime and soda, car- 

 bolic acid, &c. Their action is produced by their affinity for hydrogen, 

 which is a constituent of most of the deleterious matters fovmd in the 

 stable. They appropriate to themselves this constituent, and by this 

 means break up the jwison. Most disinfectants are also deodorizers. 



Deodorizers generally, as distinguished from disinfectants, act mechan- 

 ically. They have an affinity for certain compounds floating in the air, 

 and imbibe and absorb them. Such are sawdust, powdered wood, chai'- 

 coal, plaster of Paris, sulphate of iron, gravel, sand, and permanganate of 

 potassa. 



Deodorizers may under some circumstances become so overcharged 

 with noxious matters, that they may of themselves voluntarily give them 

 off. Earth, for instance, which is a most valuable deodorizer, may be- 

 come so loaded with impm-ities as to become stinliing. Similarly disin- 

 fectants can only combine with a certain proportion of noxious gases or 

 organic matters, and then become inert and valueless. 



Along wdth jilenty of fresh air and due regard to cleanliness, disin- 

 fectants and deodorizers are useful means of purifying the air of stables 

 and also in neutralising those noxious emanations given off from the 

 bodies and breath of diseased animals, which, if undiluted or undestroyed 

 may become fruitful sources of diseases. It must never, however, be 

 supposed that they supersede or even diminish the necessity for adequate 

 ventilation and scrupulous cleanliness.
