The deflection of the alloy circuit being negative, the alloy line is below 
| that of N. From the third column we deduce the formula 
d= —10°6516 + °859657¢ + -0001812 ?. 
The fourth column shows its accuracy up to about 400° C. Hence 

“ = ‘85965 + :00036247.

The results of experiments with the M-N junction of variable temperature 
in oil are contained in Table XIV.
