The increased work caused by the feeding by day in 

 one case, and by night in the other, resulted innnediately in 

 an increased excretion of carbonic acid. 



It is probable that the difference observed in these ex- 

 periments is chiefly the expression of the amount of work 

 iiiYolved in chewing and rumination, since the alimentary 

 canal always contains more or less fodder; but at the 

 same time it gives us a useful hint of the amount of 

 work required in the digestion of the bulky fodder of 

 herbivorous animals. 



Saving of Work by Concentrated Fodder.— A cer- 

 tain amount of work by the digestive organs is, of course, 

 necessary and unavoidable, but it is evident that the amount 

 of this work will be reduced by the use of as concentrated 

 fodder as possible. 



That is, the less the proportion of indigestible matters 

 contained in a fodder, the less of the fodder will have to 

 be eaten and worked over by the animal in order that it 

 may obtain the amounts of the several nutrients wliich it
