The tables given above of the 3", ;", and ¢''-coordinates show 
directly that the frequency distribution is of type A. It is, however 
not possible, from a mere inspection of the tables, to decide whether 
this distribution is normal or not. For deciding this question I have 
computed the skewness and the excess as well as the mean and the 
dispersion of each frequency table. The result is shown in the fol- 
lowing tables.
