It is impracticable to publish in detail all of the values obtained with the other subjects included in this study, as the mass of data is so extensive. To show the particular point emphasized in this discussion of results, namely, the probable trend of the morning metabolism from 8 a. m. to 1 p. m., an abstract of the results for 29 subjects is presented in tables 43 to 45. These tables show the weight, height, and age of each subject, the limits of the period of time in which the experiments were made, the number of individual periods included in the experiments, and the average carbon-dioxide production and oxygen consumption in the successive half hours of the day; also the number of experimental days from which each value is drawn. As in the preceding tables, grand averages are given for each subject for the carbon-dioxide production and oxygen consumption for the total number of experimental days, this being found by averaging the daily averages of each factor for all of the experiments with the individual subjects. The data are arranged according to the weight of the subjects in each group. As would be expected from the results found in tables 37 to 42, the data indicate that with these subjects, also, there is no noticeable tendency toward an alteration in the basal metabolism as the day progresses, particularly in the values for the oxygen consumption.

1Average body-weight and average age for the series of experiments.

2The experimental periods were usually 15 minutes in length and in most instances there was but one period in the half hour. The average time of the first period used was at all times approximately between 8 a. m. and 9 a. m., except as otherwise noted.

3The average time of beginning the first period with this subject was 6h30m a. m.

An examination of the detailed tables from which this abstract is made shows even more strikingly than with the subjects trained in the use of the apparatus, as were H. L. H., L. E. E., and J. K. M., that there were considerable variations in the individual values. While most of the material from which this abstract is drawn was more fragmentary than that given for the three subjects in detail, there is no evidence of a tendency for the metabolism to change in either direction during the period of experimentation.
