PREFACE IX 



Moreover, whenever circumstances permit, I have 

 endeavoured to make my own part in the book en- 

 tirely impersonal. My experience is that the constant 

 iteration by the biographer of his relationship to the 

 subject of his memoir can become exasperating to 

 the reader; so that, at the risk of offending in the 

 opposite direction, I have chosen the other course. 



Lastly, I have to express my grateful thanks to 

 all who have sent me letters or supplied information, 

 and especially to Dr. J. H. Gladstone, Sir Mount- 

 stuart Grant Duff, Professor Howes, Professor Henry 

 Sidgwick, and Sir Spencer Walpole, for their contri- 

 butions to the book ; but above all to Sir Joseph 

 Hooker and Sir Michael Foster, whose invaluable 

 help in reading proofs and making suggestions has 

 been, as it were, a final labour of love for the memory 

 of their old friend.
