Table CXXIV. — Coefficients of availability of nutrients and energy in diet with and without alcohol — Continued. 



Table CXXV summarizes the results of experiments with the same subject and the same diet 

 before and after entering the calorimeter and averages the results for all the experiments. 



Table CXXV. — Comparison of gains or losses of nitrogen, and of coefficients of availability in the preliminary periods 



outside the calorimi U r and tin i xpt riim ntal pt rinds inside.
