Not illustrated. 1915 Excerpt: ...(Without food.)--Continued. Table 17.--Respiratory exchange in comparison experiment with the ZunU-Geppert apparatus and the Benedict respiration apparatus (tension-equalizer unit). (Without food.)--Continued. As in the previous comparisons, the differences between the averages for the two apparatus have been calculated for each experiment, using the values for the tension-equalizer unit as a base-line, and are given in table 18. The results show that this difference is sometimes plus and sometimes minus, and somewhat large in several of the compari sons. The average variation is 12 c.c. for the carbon-dioxide production, 10 c.c. for the oxygen consumption, and 0.045 for the respiratory quotient. An examination of the statistics shows that there was more or less variation in the conditions during experimenting. A few comparisons, however, show results for each apparatus which are, on the whole, entirely comparable, as, for example, the experiments with T. M. C, A. G. E., L. E. E. (July 14), and D. J. M. The averages for D. J. M. are not in close agreement, but if the periods are arranged in the order in which they were carried out it will be seen that the results give slowly descending values independent of the apparatus. This subject had been somewhat active previous to the experiment in running on errands and was accordingly not in the best of condition for such observation. The largest differences between the two apparatus are shown by the subject J. J. C., these being both plus and minus. This subject was most difficult to control because of his inability to keep awake; in all probability the variations are due more to differences in wakefulness rather than to actual differences in the method of determining the respiratory exchange. An examination of th...
