The connection between changes of temperature and changes in 
the rate of growth are shown in the accompanying curves. The 
irregularity in the rate of growth shown in our Tables is here 
rendered perceptible. 
The first point that strikes one on looking at the results is the 
high temperature at which growth can go on. The following are 
the maximum temperatures of five experiments :— 
56^5 C. 57?:5 C. 
54°°5 57°5
