lot are summarized in Figure 14, which in A plots the mean rate per 

 hour per living individual in the isolated (solid) and aggregated state 

 (broken line). The broken line is drawn as the mean of the two 



Fig. 14. — Showing, A, the mean rate of oxygen consumption per hour at the be- 

 ginning and during successive fifths of the starvation period; each space on the ordi- 

 nates represents i cu. mm. oxygen. B, The mean oxygen consumption; each space on 

 the ordinates represents 100 cu. mm. of oxj-gen. The broken line gives the respiration 

 of the bunched individuals.
