THE NUMERICAL RESULTS OF THE EXPERIMENT. 



A large amount of data was necessarily recorded in an experi- 

 ment involving such numerous weighings and analysis during 

 nearly three months. 



The figures herewith presented have been reduced to those 

 which are essential to a critical analysis of our conclusions. 



Those which follow are displayed under several heads: 



(1) Periods represented by the several samples of foods. 



(2) Daily weights of foods and content of nitrogen and fat. 



(3) Daily weights and partial composition of the milk, urine 



and feces. 



(4) Daily composition of milk, and yield of milk and milk 



solids. 



(5) Digestibility of rations and amount of digestible food 



daily. 

 (G) Amount of water drank daily. 



(7) Daily balance sheet, nitrogen and fat, 



(8) Balance sheet, nitrogen, totals by periods. 



(9) Balance sheet, protein, daily average for periods. 



(10) Balance sheet, fat, totals by periods. 



(11) Balance sheet, fat, daily average by periods.
