1) Calculated bij Macdonell (1904). 
2) Adult male Egyptians accused of crime. 
3) Calculated from the mean headlength and the mean headbreadth. 
4) Cit. from Pearson in Schuster (1911, p. 49). 
5) Standard deviation is calculated by me. 
6) A very small series of crania (Macdonell 1906, p. 103). 
7) These values are small, comprehensible from the series of numbers of 




























the classes for headlength and headbreadth (Retzuis and First p. 112, 114).
