Various kinds of Refuse. 25 



The inorganic part was found, upon analysis, to contain 



It will be observed that every gallon of this refuse contained 

 upwards of Ib. of organic nourishment, and a very considerable 

 proportion of phosphates constituents which occur in large 

 quantities in milk. 



2ndly, The thicker liquid, which is deposited at the bottom of 

 the tank, is of sufficient consistence to be given alone as food 

 for pigs. 



An imperial gallon of this liquid left 10,884 grains of dry solid 

 matter, or no less than 3 Ibs. of dry food in every 2 gallons. 



This solid matter consisted of 



Grains. 



Gum, sugar, albuminous and other organic compounds .. 10,290 

 Inorganic matters (ash) 594 



The inorganic matter, or ash, was found to contain 



10,884 



Like the thinner liquid, the thicker is rich in phosphates and 

 in organic substances which tend to produce milk. 



Professor Johnston remarks on these analytical results : " It 

 may be interesting to present a comparative view of the relative 

 proportions of water and of organic and inorganic matters in each 

 of the liquids, and in turnips of average constitution. 100 Ibs. 

 of each contain these three kinds of matter nearly in the following 

 proportions :
