the other lot of cows as they had on those to which they were 

 given originally. There was no interval at all between the 

 two experiments. The second experiment, here described 

 as Experiment L, commenced on February 16, and continued 

 till April 25, 1908. The results are given in the following 

 tables. Table XLIL shows the yield of milk in each lot. 



In comparing the respective yields of milk given by the 

 two lots of cows (see Table XLII.), it is again necessary to 

 confine ourselves to the period of the first eight weeks of the 

 experiment. When the rations were reversed it is unfortu- 

 nate to have to record that lot II. never quite took to the grains 

 and only with reluctance ate them. In spite of this fact, 

 lot II. receiving the grains gave, during the period named, 

 a greater average yield of milk than lot I. If the greater 

 increase in the quantity of milk yielded in Experiment K was 

 due to the brewers' grains the result in Experiment L is what
