'For the student of the History of Science, as well as for the student of Galton- this volume is of prime importance. . . .The voli 

 important and deeply interesting. It is splendidly illustrated." — Glasgow Herald 



"Galton's personality and achievements have taken their place in the history of science, and more than justify the sumptuous 

 Letters, and Labours' on which Professor Pearson has lavished special knowledge and labour." — The Times Literary Supplement 



'It is a wholly worthy memorial of a very great man." — Science 



' We prophesy that Pearson's Life of Gallon will be ranked by our descendants not very far behind Boswell's 'Johnson,' and Treve 

 MacaulayV — British Medical Journal 



' If our race continues to progress in the right direction, our descendants of, say, five or ten centuries hence will be insatiable in 

 need of information about such men as calton and darwin. They will bless Pearson for his devotion. If the greatness of a man is 

 Treasured by the product of his originality by his energy — and this seems the right way of measuring it — GALTON is certainly a very 

 nan and his greatness will increase, and not decrease, as years and centuries go by." — Isii
