 biosis (total time in oxygen-free medium minus time during which the 

 oxygen bound to haemoglobin at the beginning of the exposure was still 

 available), 61 minutes. CB', oxygen uptake during recovery from anaero- 

 biosis (the amount of oxygen used for the reoxygenation of the blood has 

 been subtracted). CC, theoretical curve that would have resulted if the 

 animal had not repaid its oxygen debt. (According to Borden, 1931.)
