The correlation coefficient for the first Report containing 1405 pairs of 
judgments is r = '47 ; that for the second which includes 2018 pairs is r = "50. 
This result should be looked upon as a measurement of the intelligence exhibited 
by boys in different subjects rather than as a measurement of the personal 
equation between different masters. I have also employed a contingency table to 
examine the pairs of judgments by the same master at different times.
