The results, as would have been expected, are not mark- 

 edly different from those obtained in "the preceding experiment. 

 The results in the second experiment are lower than in the first, 

 with the exception of the digestibility of the ether extract and 

 nitrogen-free extract. It should be noted, also, that, although 

 the alfalfa used in Experiments I and II was from the same 

 field and cut and cured at practically the same time and under 

 similar conditions of weather, the analysis shows quite a range 

 in composition.
