* Digestion by ruminants, based upon summary by Kellner. 



f In estimating these values the unit-value of nitrogen, phosphoric acid, and 

 potash have been taken at 12s. , 3^., and 4^. respectively, and it has been assumed 

 that the combined excrements, when applied to the land, contain one-half of the 

 nitrogen, three-quarters of the phosphoric acid, and the whole of the potash contained 

 in the ton of food. 



+ Data for these foods are not included in Hall and Voelcker's table. 



ton demanded must not exceed 127 x is. 3jd., i.e., £8 is. 6d. 

 The price actually charged is thus probably somewhat in 

 excess of the value of the cake as compared with Cake A at 

 £g per ton.
