temperature optj for any process is that temperature 

 which is the middle point of a range of temperature for which 

 perat ire coefficient is unit

 A • hed process - temperature graph, similar 

 temperature graphs of figures 2-5, is first constructed, 

 ing a.s short temperature intervals ahout the apparent ax- 

 i as is possible. thi . are read ordinate values 

 lately short inte -, for some distance on either 

 of the apparer " . Fro ordinate ( ra J 

 valves are calculated the temperature ccef its for equal 

 temperature ranges whose lower limits are as near together as 

 is pcssihle. finally, the coefficient values are plotted as 

 ordinates on a graph whose abscissas ere the i Le points of 

 the temp : e ranges employed fo>~ car:'- coefficient, 

 and this ' jotted in the usu- 3 sr. - derived 



temperature for the process in question is that tempera- 

 ture which: is represented by the abciasa of that point or the 

 graph whose ordinate is 1.0. This procedure howe has not 

 been followed in the \. t paper. 



Still another poin* ths t needs emphasis i tudy of 

 the p-eneral nature of .1 erature coefficients of all pro- 

 cesses tl it havs * . rature minima and maxima, is this, that 

 ever.v such process must show a cert* i t< perature range for
