with water, forming carbonate of ammonia, which is 

 rapidly lost in the atmosphere, unless absorbed by earth, 

 peat, swamp-soil, etc., or changed into the non-volatile 

 sulphate of ammonia by gypsum, or sulphuric acid. In 

 addition to the urea, and some other organic matter, 

 urine contains potash, soda, and phosphatic salts.
