There is good reason for believing that the dry moss system 
could be also advantageously applied to public urinals by causing it 
when once used to be dried by exposure to air under agitation, to be 
resaturated in the urinal, and repeating these processes as long as 
found practicable. A laboratory experiment in imitation of such 
treatment may here be noted. The quantity of moss litter used for 
it was 158 grammes, and to this there were added, from time to time, 
14-15 grammes of ordinary oil of vitriol diluted with water. To this 
mixture fresh urine was added whenever the evaporation of the excess 
of moisture rendered absorption possible. This experiment lasted 
for about three months, and at the end the mixture weighed 474 
grammes, which decreased on air-drying to 346 grammes. A sample 
of this, marked moss manure, U No. 1, gave:
