Taking the weights recorded above as an indication of the extent 

 of errors that are likely to occur in work of this kind, there is rea- 

 son for considerable confidence in the apparent results of a feeding 

 experiment continued for over four months. Another error always 

 accompanying experiments in feeding for growth is the varying capaci- 

 ties of different animals for utilizing food in the direction of growth. 

 This error can be eliminated in part, at least, by changing the rations 

 so that each of two rations to be compared shall be fed to the same 

 animal or animals for a certain length of time. Another method of 

 doing the same thing is to feed all the animals on the same ration for 

 a time, and then use the comparative results as a basis for correcting 

 the apparent gain on different rations. The former method was 

 used by the Station in the experiments previously discussed.
