This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...is lying quietly in bed asleep, and at the end of the period, 9 a. m., he is riding a bicycle ergometer at a high rate of speed. Again, at 11 o'clock at night the subject is sitting dressed, possibly reading or writing, and at 1 a. m. he is sound asleep, covered with bed-clothing. It is during these two periods, when the widest variation in bodily activity naturally takes place, that We find the greatest discrepancies in the measurement of the volume of oxygen. These discrepancies are indicated generally by abnormal values for the "respiratory quotient." (Seep. 184.) In the particular experiment the results of which are presented in this report (p. 177) these discrepancies do not appear. CONCLUSION REGARDING THE ACCURACY OF THE OXYGEN COMPUTATION. This method of calculation is found to be far more practicable and on the whole more satisfactory at the present state of our experimentation than a method depending upon analyses of air at the end of each period; for the difliculties in securing proper temperature measurements of the large volume of air affect alike the calculation of the total residual oxygen whether the analysis of a sample is made by the most approved methods or whether the computation method is employed. It is therefore believed that the errors involved in the system of calculations as above outlined are certainly no greater than those that necessarily occur in using direct analyses of oxygen under present conditions. CHECK ON THE COMPUTATION METHOD OF DETERMINING OXYGEN. The method of computation outlined on pp. 86-90 gives the amounts of oxygen and nitrogen present in the air at the end of each period; consequently at the end of any experimental period we can calculate the percentage composition of air free...
