with increasing temperature. At 0° the third derivative of the 

 resistance as a function of pressure is positive, at 50° it is zero, and at 

 100° it is negative. 



Mercury. I have already pubHshed results for the resistance of 

 liquid mercury as a function of pressure and temperature,^^ but I 

 have now found it possible to considerably extend the range of the 

 previous work. Previous work on the liquid was between 0° and 50° 

 and to 6500 kg., and a few very rough qualitative results were obtained 

 for the solid. The results for the liquid have now been extended over 

 the temperature range 0° to 100° and over the pressure range to 12000 

 kg. In addition, the resistance of the solid has been accurately meas-
