When amalgams of the same cadmium content were 

 melted and chilled, the cells containing them did not always 

 have the same E.M.F. even after several weeks. However, 

 the differences were comparatively small for the amalgams 

 containing more than 14 per cent, of cadmium : thus after 

 30 days at 0° C. two cells containing 16 per cent, chilled 

 amalgams had E.M.F.'s of 1-02947 v. and 1*02931 v., and 

 two other cells with 18 per cent, amalgams had E.M.F.'s 

 of 1*03335 v. and 1-03310 v. 



In two instances there were very rapid rises in E.M.F. 

 and subsequent rapid falls ; one instance is the 13 per cent, 

 amalgam cell of Table VI., and in the second case a 16 per 

 cent, chilled amalgam cell had an initial E.M.F. of 1-04097 v.,
