232 MAINE AGRICULTURAL EXPERIMENT STATION. 1908. 



fresh samples of corn were used. It will be noted that the 

 average results obtained with the protein in the first period are 

 quite different from those of the third period, although both 

 were made with the simple diet. So, too, the average results 

 of the second and fourth periods, with the mixed diet, differ by- 

 over three j)er cent. How far this variation is due to differ- 

 ences in the corn itself it is impossible to say.
