There are no previous measurements of the pressure coefficient. 



The temperature measurements were continued from 100° to 170°, 

 because a polymorphic transition has been suspected above 100°. 

 In fact I did find a discontinuit}' in resistance at about 145°, thus veri- 

 fying the approximate location of a transition as found by Jaenecke.-^^

 The coefficient is constant between and 12000 kg. 



No trace of the transition was found at any pressure in the temperature 

 range of the measurements above, however, and the results are un- 

 affected by the existence of the transition. The study of this transi-
