Animals were subjected to anaerobic conditions largely by immersion in water at 25° C. for varying periods of time. Immersion in water was found to give results identical with those produced by the gases hydrogen, carbon dioxide or nitrogen. Animals were first put in the manometers and their normal rates of oxygen consumption determined. After removal from immersion in water they were again quickly put in the same manometer and their rates of oxygen consumption during re- covery noted. By such a procedure a continuous record of the oxygen consumption of the organism was obtained except for the actual period of immersion in water. Blood pH determinations were made by micro-colorimetric methods (Bodine, 1925). By means of fine capillary pipettes blood was easily obtained from minute punctures made by fine needles in the lateral abdominal wall of the f 6 7 ft 9 /» TIME //y HOURS FIG. i. Curve showing the effect of immersion in water for 75 minutes on the rate of oxygen consumption of a male, nymph, Melanoplus differ entialis. Space within arrows indicates the period of immersion of the animal; points on curve, the rates of oxygen consumption before (which is taken as 100 per cent.) and after im- mersion.
