BRIDGMAN. 



The maximum departure of any point from a smooth curve was 0.6% 

 of the total effect, and the average numerical departure was 0.15%. 



TABLE XI. 

 Nickel. 



The deviations from linearity are distinctly not symmetrical; they are 

 also reproduced in Figure 13. 



The average temperature coefficient between 0° and 100° was 

 0.00487. This would indicate a metal of fairly high commercial 



Pressure, Kg. /Cm.' X 10' 



Figure 13. Nickel, results for the measured resistance. The deviations 

 from linearity are given as fractions of the resistance at kg. and 0°C. The 

 pressure coefficient is the average coefficient between and 12000 kg.
