of sewage-irrigated and ordinary meadow grass, with the use of 

 malted foods, with the value of ensilage ; but these will be 

 dealt with separately. 



Speaking generally, these feeding experiments of Lawes and 

 Gilbert, while they will not bear the exact analysis to which 

 later experiments carried out in respiration chambers can be 

 subjected, so that the digestibility of the foods and the portions 

 which go to maintenance, increase, and work respectively can 

 be ascertained, yet gave a sound general idea of the broad 

 principles of animal nutrition as they affect the farmer. They 

 are noteworthy for the intuition with which correct opinions of 

 the general processes were deduced by statistical means from 

 experiments carried out in the main under ordinary farming 

 conditions, opinions which have in all cases been abundantly 

 verified by later and more accurate research.
