40 Dr. G. Gore. Chemico- Electric Relations of [Dec. 18, 



enable curves to be drawn showing the variation of relative electric 

 positions of different metals with the variations of strength of the 

 liquid. Such curves were drawn, compared with each other, and 

 conclusions inferred respecting similar metals or groups of metals. 



In the following tables the numbers at the top of each column 

 represent the numbers of grains of the particular salt dissolved in the 

 quantity of water stated. The amount of water employed in the solu- 

 tions of the first six tables was 50 cub. centims., and in Tables YII 

 and VIII it was 800 grains. 



The specimen of gallium not having been obtained in sufficient time 

 for the whole of the experiments, it was not employed in Tables I and 

 VII and part of Table III. Being also easily fusible it could not be 

 used in hot solutions.
