§26. For good, clean, alfalfa hay the ratio of thoroughly 
air-dried feces to the hay consumed is one to two and seven-tenths or 
five and one-half pounds of hay eaten will correspond to just a 
trifle more than two pounds of feces. 
§27. The silicic acid has not been taken into account in the 
preceding analyses because it is very uncertain how much of it is 
due to fluxing of the minerals constituting the dust and sand found 
in the ash. 
§28. These data show the extent to which the potash is taken 
up by the animal system, the feces being very poor in this substance
