possibility of such a transition with a very shght discontinuity of re- 

 sistance is not entirely ruled out by these measurements, although it is 

 exceedingly improbable.

The smoothed results are collected in Table VH, and the experi- 

 mental values are sho-mi in Figure 9. Within the limits of error the 

 deviations from linearity are symmetrical and parabolic, and are 

 sufficiently characterized by the values of the table.

Figure 9. Aluminum, results for the measured re.sistance.^.The deviations 

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

 the deviations are symmetrical, there is no need for giving the detailed devia- 

 tion curves. The pressure coefficient is the average coefficient between 

 0° and 12000 kg.
