to behave differently from any of the 

 so far as the curves obtained when the 

 metal was first heated were irregular in outline and very 

 broad. The maxima were not as definite as in the preceding 

 cases, and the displacement corresponded to a smaller value 

 of e\m. The character of these curves is well shown by the 

 curve with points thus : — X in fig. 1.

After the gold had been heated for some time the curves 

 assumed a more normal shape and at the same time the 

 distance between the maxima increased. The curves with 

 the points marked thus : — in fig. 1, which were obtained
