It is, of course, possible that the oxygen tension at which the effects of oxygen deficiency appear, may not be the same in the presence of high tensions of carbon dioxide as in the relative absence of this gas. If the above experiments had been carried out in the region of oxygen deficiency, however, even slight increases in the oxygen tension would have resulted in an increased rate of oxygen consumption. That this was not the case is shown by a comparison of experiments 18 and 19 (Table II) which show that when the oxygen tension in tonometer B (C(X) in experiment 18 was 62 per cent greater than that in tonom- eter B (CO2), experiment 19, the differences in the rates of oxygen consumption lay within the error of the method. The carbon dioxide tensions in the two tonometers B (CO2) do not differ by enough to affect appreciably the rates of the oxygen consumption in the two ex- periments.
