* These temperatures were read directly from the standard curve, no 

 account being taken of the differences in electromotive force of the element 

 actually used and the standard element. Since, however, these differences 

 were always small and correspond to less than 1'0°, and since the standard 

 curve changes in curvature very slowly, no error is introduced thereby into 

 the change of melting point caused by pressure, the quantity in which we 

 are chiefly interested.
