depressions. It is therefore clearly demonstrated that there are influences 

 which obscure a correlation at definite points, but in this table III, not- 

 withstanding this influence, it is very convincingly seen that correlation really 

 exists. That the situation is in very truth something more than this can 

 be learnt from table IV. 



table IV 



Here we also see the maxima moving in zig-zag form over the table. 

 Yet it is not possible to trace the correlation-diagonals as was done in 

 tables I, n and HI. It is however possible to trace here a multiple of 

 diagonals, e. g. line 11 — 52, line 135 — 127, line 112 — 75 &c. These diagonals 

 are not however to be traced through. Thus indeed we have to admit (just 

 as we have seen on a small scale in table III) that influences are present 

 which veil the correlations from our sight. Yet, however weak, there still 

 is a germ of correlation present in table IV, which becomes clearest when 

 we compare it with tables V and VI.
