curve, a table of {.%■) for Type B and a discussion of the dissection of a frequency distribution 
into components in which some approximate results are given and the suggestion of shortening 
the solution of the fundamental nonic by means of graphical work is made. 
We have jiut forward the above criticisms to show the practical difficulties we have met in 
using the suggested methods ; though these difficulties seem very important to us they do not 
blind us to the energy and ingenuity expended on the papers.

As this is hardly the type of statistical work that will appeal to our readers it is unnecessary 
to criticise it.
