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 were collected, the preliminary feeding; 

 of the first seven days being considered necessary to entirely free 

 the digestive apparatus from any residue of former food. Fortu- 

 nately the rations were completely consumed, except in two- 

 instances, where the amounts uneaten were too small to materially 

 affect the results. The feces were collected twice each day, weighed 

 on a balance sensitive to one-half gram, and from the whole 

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



The data needed for calculating the coefficients 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.
