From Equations (xxii) to (xxv) on p. 240, we get the fully 

 corrected raw moments to be : —

In our case the range /> = 9, and we get : —

\\ T here the curled brackets give the correction over and above 

 Sheppard's correction. 



Thus we get fully adjusted raw moments to be

Transferring to the Mean (which itself is now changed) we 

 obtain the Moment-Coefficients about the Mean. 



Moments after " full correction"

 and the Mean = 1656-5043 mm. 

 with S.D. = 67-1950 mm.
