correlation occurs when least crowding exists. In line 50, series 63, the 

 coefficient is .673 ± .024, this being the lowest coefficient. The highest 

 is .896 ± .008, for series 100, the difference being .223 ± .025, which is 

 significant. In line 62 the extreme coefficients differ by .182 ± .022,
