The following table gives various temperatures of the heated junction of 
the M-N circuit, with the corresponding deflections.

(1.) Alloy of which 20 per cent. is Palladium. 
The signs of the deflections show that if the current flows from M to N, 
across the heated M-N junction, it flows from N to AgPd.» across the 
heated junction of these substances. Hence the diagram lines of M and 
AgPd,, are on opposite sides of the N line. From the above observations 
we deduce the formula 
d= —9°015 + 6362+ 0005622? .
