Not illustrated. 1910 Excerpt: ...frequently demonstrated that in experimental periods as short as 1 hour, it is possible to determine all three factors, carbon-dioxide production, oxygen absorpl"i 1, 9-I111 Water vaporization to within an error of i 1 to 2 per cent.' Usually the values found in the control tests are inside of this limit of error. Almost invariably in experiments of 3 to 5 hours' duration, the total sum of carbon dioxide preduced and oxygen absorbed will be very close to theory. I11 Practically all of the experiments with diabetics it was possible to secure ex ' Benedict, Rlche and Emmes, Am. Journ. Physio1., 1910, 26, p. 1. periments of 2 or 3 horns or more in length. In nearly all cases it was also possible by means of the gas analysis apparatus, to divide the measurements into 1-hour periods, and hence the values are given in hourly periods as a general rule. The carbon-dioxide determination for such periods has been proved repeatedly to be extremely exact. On the other hand, the determination of the oxygen consumption and the apportionment of the oxygen for the different hours of an experiment continuing 2 or 3 hours may be somewhat at fault and occasionally abnormally high respiratory quotients have been obtained in one period and abnormally low quotients in the other, which would indicate a discrepancy in the oxygen measurement. While as a. rule, therefore, the ozygen determination for the whole experiment may be looked upon as exceedingly accurate, in many instances the values for the oxygen consumption in 1-hour periods may be at fault. In general, however, we believe that the oxygen measurements as here reported in periods of 1 hour are well within the limit of error in physiological experimentation.
