the narrower ration relatively large amounts of the oil meal, and for 

 the wider ration relatively large amounts of barley meal were used. 



(1) Effects ofone-sidrd increase of nitrof/rnoii.s/ood. — To test the eftects 

 of large rations with narrow nutritive ratios, two series of experiments, 

 scries C and D, were made. In each series the ditierent rations were 

 made up by taking one basal ration for all and adding oil meal and 

 barley meal in different relative ]»roportions.
