GALTON PROFESSOR, UNIVERSITY OP LONDON 
In Biometrika, Vol. VIII, 191 1^ the Editor promised an account of 
the lifework of Francis Galton. That account out-grew the limits of 
this Journal, and the first instalment has now appeared in the above 
issue. 
" It is not too much to say of this book that it will never cease to be memor- 
able. Never will man hold in his hands a biography more careful, more 
complete." — The Times 
" A monumental tribute to one of the most suggestive and inspiring men of 
modern times." — Westminster Gazette 
" It was certainly fitting that the life of the great exponent of heredity should 
be written by his great disciple, and it is gratifying indeed to find that he has 
made of it, what may without exaggeration be termed a great book." — Daily

Tables for Statisticians & Biometricians 
Edited by KAEL PEARSON, F.R.S. 
~ GALTON PROFESSOR, UNIVERSITY OP LONDON 
ISSUED WITH ASSISTANCE FROM THE GRANT MADE BY THE WORSHIPFUL 
COMPANY OF DRAPERS TO THE BIOMETRIC LABORATORY. 
" To the workers in the difficult field of higher statistics such aids are invaluable. Their 
calculation and publication was therefore as inevitable as the steady progress of a method which 
brings within grip of mathematical analysis the highly variable data of biological observation. 
The immediate cause for congratulation is, therefore, not that the tables have been done but 
that they have been done so well The volume is indispensable to all who are engaged in 
serious statistical work." — Science 
" The whole work is an eloquent testimony to the self-eflPacing labour of a body of men and 
women who desire to save their fellow scientists from a great deal of irksome arithmetic ; and 
the total time that will be saved in the future by the publication of this work is, of course, 
incalculable To the statistician these tables will be indispensable." — Journal of Education 
" The issue of these tables is a natural outcome of Professor Karl Pearson's work, and apart 
from their value for those for whose use they have been prepared, their assemblage in one 
volume marks an interesting stage in the progress of scientific method, as indicating the number 
and importance of the calculations which they are designed to facilitate."— Post Magapine
