It has long enjoyed popularity as a source of clear descriptions of the  practical use of Pearson and also Gram-Charlie systems of frequency  curves. Professor Johnson has substantially revised this book. The  material on correlations has been omitted; descriptions of further kinds  of frequency curves have been added; the treatment of frequency  surfaces has been recast and broadened; and the opportunity has been  taken to amend the original text in the light of later research. The aim  of this book remains essentially practical. There is no attempt at  encyclopaedic coverage of all known systems of frequency curves and  surfaces. It should be of especial value as a quick reference book (for  statisticians and non-statisticians alike) for formulae and methods used  in fitting frequency curves.
