This trsat esulted in several graphs J fun- 



gus, and a comparison of these crrapris brings out certain fc. 

 of the march of the growth- temperature relation aa it cnar.ged 

 throughout the exposure period. 



These growth-temperature graphs were constructed in the 

 ordinary way. For the given fungus and observation period the 

 mean 24 hour rates (first part of Tables III - VI) '.-tie plctted 

 as ordinates and the indices of maintained temperature .vere 

 plotted as abscessas. After the points were in place a smoc 



ed graph was drawn In the regular manner* 



Tc illustrate this process of smoothing, the four 

 graphs for the second 24-hour period after inoculation a»-e 

 shown together in Figure 1. The points shown en or near e 

 smcct v ed graph represent the mean rates taken from the table. 

 It is seen at once that they arrange themselves ir a very sat- 

 isfactory lisrner as regards the smoothed graph , i.-s., that 

 the process cf smoothing introduces only very slight alterations 

 from any of the values derived directly from observations. 

 These four second-day graphs are representa .rs. 



All are shown (without the points -- the value for which may 

 t e obtained from tables III - VI, oo;-e\^r) in figures 2 -5, 

 each figure presenting the several smoothed graphs for a sin- 

 gle fungus.
