Preface vii 



is given in a statistical laboratory, nor does it profess to provide an account 

 of the innumerable uses to which they may be put, or to warn the reader of the 

 many difficulties which may arise from inept handling of them. Additional aid 

 may be found in the text which usually accompanies the original publication of 

 the tables. 



In conclusion here I wish to thank the loyal friends and colleagues Dr W. F. 

 Sheppard, Mr W. Palin Elderton, Dr Alice Lee, Mr P. F. Everitt, Miss Julia Bell, 

 Miss Winifred Gibson, Mr A. Rhind, Mr H. E. Soper and others whose un- 

 remitting exertions have enabled so much to be accomplished, if that much is 

 indeed not the whole we need. I have further to acknowledge the courtesy 

 of the Council of the British Association, who have permitted the republication 

 of the Tables of the G (r, v) Integrals, originally published in their Transactions. 



To the Syndics of the Cambridge Press I owe a deep debt of gratitude for 

 allowing me the services of their staff in the preparation of this work. Pages and 

 pages of these Tables were originally set up for Biometrika, or were set up afresh 

 here, without the appearance of a single error. To those who have had experience 

 of numerical tables prepared elsewhere, the excellence of the Cambridge first proof 

 of columns of figures is a joy, which deserves the fullest acknowledgement. 



Should this work ever reach a second edition I will promise two things, 

 rendered possible by the stereotyping of the tables : it shall not only appear 

 at a much reduced price, but it shall be largely increased in extent.
