AGRICULTURAL EXPERIMENT STATION. 



attached to the animal by a light leather harness, and any loss of 

 either fodder or dung could be easily detected. 



The feeding period with each food was twelve days, during the 

 last five of which the feces was collected, the preliminary feeding of 

 the first seven days being considered necessary to entirely free the 

 digestive apparatus from any residue of former food. Fortunately 

 the rations were completely consumed, except in two instances 

 where the amounts uneaten were too small to materially affect the 

 results. The feces was collected twice each day, weighed on a 

 balance sensitive to one-half grain, and from the whole amount, 

 carefully mixed, one-tenth was taken and dried for analysis. 



The data needed for calculating the coeflScients of digestibility are :' 



(1) The composition of the foods eaten. 



(2) The composition of the feces. 



(3) The weight of food eaten and dung excreted. 



The composition of the fodders has already been given. That of 

 the feces follows. The second contains the weights of food con- 

 sumed, and of solid excrement voided.
