EVACUENTS. 171 



Ammonium, Potassium, Sodium, Hydrochloric Acid, 

 etc. 



Chlorine is the most powerful of all the disinfec- 

 tants and deodorants, an antiseptic and antiferment 

 of great activity, its power being due to its affinity 

 for H, decomposing all bodies which contain this ele- 

 ment as a molecular constituent, forming HCl, and 

 setting O free in its nascent form of ozone. Locally 

 chlorine is highly irritant to the skin and mucous 

 membranes. When inhaled in quantity it causes 

 cough, sneezing, spasm of the glottis, and inflamma- 

 tion of the respiratory mucous membranes and of the 

 lungs. For actions and uses of its various com- 

 pounds, see under their respective headings.
