130 The Correlatiou CoeJjUcient of a PolycJionc Table 
II. The second table examined was taken from Macdonell's paper " On Criminal 
Anthropometry/' Biometrika, vol. i, p. 216. The original table is too extensive to be 
given here, but may be found in loc. cit. The horizontal categories are the heights of 
3000 criminals in feet and inches, and the vertical categories the lengths of their 
left middle fingers in millimetres. The correlation coefficient found by the product 
moment method is -6608 ± -0069.
