SUMMARY AND DISCUSSION OF RESULTS. 
The purpose of the experiments was to find what proportions 
of the different nutrients of the food would be digested and 
made available to the body, and what proportion of the energy 
of the food would be utilized by the body. These figures which, 
as previously explained, are designated as coefficients of avail- : 
ability, are summarized in the following table. The upper | 
portion of the table gives the coefficients for the nutrients and 

energy of the total diet, including milk, cream, sugar and break- 4 
fast cereal, whereas the lower portion gives ae coefficients for a 
the cereal part of the diet alone. 5

Results for total diet.—In the three experiments with Grape- 
Nuts the coefficients for total organic matter agree very closely 
for all three subjects, the range being from 93.6 to 94.5 per 
cent. The coefficients for fat, carbohydrates and energy are 
likewise in very close agreement, but those for protein vary 
somewhat, the range being from 85.1 per cent. with one subject 
to 89.3 per cent. with another. The coefficient for the third 
subject is almost identical with the average for the three. 
The agreement in these results is therefore considered quite 
satisfactory.
