ured at 0° between the solidifying pressure (7640) and 12000 kg,, and 

 the change of resistance on soUdifying at 0° has been also determined. 

 The liquid was measured with the Carey Foster bridge, by the same 

 method used for most metals in the form of fine wire. The mercury 

 was contained in a U-shaped capillary, and connections were made to

the mercury by amalgamated copper wires dipping into cups at the 

 upper ends of the U. The resistance was about 10 ohms. The capil- 

 lary was of Jena glass No. 3880a, the same grade of glass as that used 

 in the previous work. This particular capillary was blown in 1907,
