When following up these experiments half a year later — the experi- 

 mental arrangement being the same as in the foregoing paper — we 

 found irradiation with 2000 r not to influence the exhalation of ^^COg 

 which follows injection of bicarbonate (Fig. 1). Concomitantly a shift 

 in the reaction of the animals against adrenaline had occurred. In the 

 previous investigation 2 y adrenaline, given subcutaneously 15 min 

 before the injection of the labelled bicarbonate, was found to decrease 

 the I'^COg-output by about 30% in contrast to an increased output of 

 24% found in the present investigation (Table 1).
