DISINFECTION. 



In order to permanently deodorize the fae- 

 cal matters and urines, it is necessary to pre- 

 vent their putrefaction, by incorporating them 

 with substances which will neutralize or ab- 

 sorb the volatile and odorant products of de- 

 composition, as fast as they may be generated. 



In urine there are small quantities of lac- 

 tate, urate and phosphate of ammonia, a lar- 

 ger proportion of urea, some sulphur (accord- 

 ing to Proust,) and undefined animal matters. 

 The faecal matters consist chiefly of vegetable 

 and animal debris, in which there is necessa- 

 rily an appreciable quantity of sulphur. Now, 

 urine decomposes at a moderate temperature, 

 and is transformed into carbonate of ammo- 

 nia; the sulphur seizes upon the H3^drogen 

 of the organic matters in a state of decay, and 

 forms sulphuretted hydrogen. It is therefore 

 the Hydrosulphate and carbonate of ammonia
