Fig. 6. The Deviations of the Electromotive Force of Thallium Amalgams. 



7? f r 



Deviations from the expression w = : ~p ln ^ are plotted in millivolts as ordinates, 



the logarithms of the concentration ratios as abscissae. The most concen- 

 trated amalgam contained 1.85 per cent by weight of thallium and 98.15 

 per_ cent by weight of mercury. A horizontal line on the diagram would 

 indicate complete fulfilment of the concentration law. This curve is almost 

 if not quite independent of temperature, at least between o'and 30".
