 diminishes, and in others, for instance, Nos. 155 and 156, is actually 

 reversed. 



The following table and diagram represent the change which 

 occurred with the solution composed of 14 oz. of water and 2 oz. of 

 chrome alum (No. 156); (those of sulphate of nickel (No. 155), and 

 bromide of nickel (Nos. 106 and 139), are also shown for three tempe- 

 ratures each in the diagram). The dotted lines represent the elec- 

 trical states of the heated platinum.
