Tj, co ll, constructs some curves of t mperature coefficients 

 showing how they decrease rapidly from high values at 1. 

 peratures to low values at higher temperatures. 



Tempe rat :re_co_eff icient in the present study : The 

 growth temperature relations of the four fungi used in the work 

 here reported were studied in certain respects by i/.eans of such 

 temperature coefficients as hare previously "been described. 

 Since unexplained fluctuations in growth rate as related to 

 temperature are to be neglected, it being desired tc tain 

 information of a general nature only, the mean 24 hour rates 

 for the Tarious 24 hour observation periods (given in tables 

 U- 32} were not employed in calculating the temperature co- 

 efficients. Instead of these, the length of the ordinates for 

 each decree on the smoothed graphs of figures 2-5 were used. 

 These ordinate values are presented in ta v les IX - XII. T^e 



arrangeioent and notation of the first parts of tables UF- 2T 

 are here followed.
