PREFACE
In writing my husband's life I have tried, so far as it was possible, to let him, especially in matters scientific, speak for himself.
For the purpose of his biographer it is unfortunate that my husband lived in almost daily intercourse for parts of many years with more than one of his most intimate friends. Hence there are no letters to several people with whom he was in the habit of discussing scientific, philosophic, and theological questions.
The letters relating to his work will, I hope, interest any one who cares for biological science. Whatever may be the exact place which shall be assigned to him, by those who come after, in the great army of workers for Science, this much may be said: that no one ever served in the cause of Science with more passionate and whole-hearted devotion, more entire disinterestedness—
All for Love, and nothing for Reward.
I have to acknowledge the kindness of many who have put letters at my disposal. I cannot sufficiently express my thanks to Mr. Francis Darwin for generously allowing me to print portions of the correspondence which for seven or eight years was one of the chief pleasures and privileges of my husband's life. I must also thank my brother and sister-in-law, the Dean of Christ Church, Professor Poulton, Professor Schäfer, Professor Le Conte, Mr. Thiselton-Dyer, and others for like permission.
