| The deflections of both circuits being of the same sign, the line of this alloy 
must be above that of palladium on the diagram. The following is the formula 
deduced from the third column of the above table :— 
6 = —'91017 + 064227 + 00019887’. 
) The fourth column shows the accuracy of this formula up to nearly 380° C. 
Hence 
dé 
Gp = 06422 + 00089767. 
aig 10 
If, therefore, f= 0C.,7= 06422, 
and if t= 300° C,, = "1835.
