"No one except my mother, knows the full amount of suffering he endured, or the full amount of his wonderful patience. For all the latter years of his life she never left him for a night, and her days were so planned that all his resting hours might be shared with her. She shielded him from every possible annoyance, and omitted nothing that might save him trouble, or prevent his becoming overtired, or that might alleviate the many discomforts of his ill-health. I hesitate to speak thus freely of a thing so sacred as the life-long devotion which prompted this constant and tender care. But it is, I repeat, a principal feature of his life, that for nearly forty years he never knew one day of the health of ordinary men, and that thus his life was one long struggle against the weariness and strain of sickness. And this cannot be told without speaking of the one condition which enabled him to bear the strain and fight out the struggle to the end." That Darwin himself appreciated the goodness of his wife can be seen from the following tribute which has appeared in _More Letters of Charles Darwin_. It does not appear in the _Autobiography_ because Mrs. Darwin was living at the time of its publication. Where in all literature can a more tender and beautiful appreciation be found?-- "You all know your mother, and what a good mother she has been to all of you. She has been my greatest blessing, and I can declare that in my whole life I have never heard her utter one word I would rather have been unsaid. She has never failed in kindest sympathy towards me, and has borne with the utmost patience my frequent complaints of ill-health and discomfort. I do not believe she has ever missed an opportunity of doing a kind action to any one near her. I marvel at my good fortune that she, so infinitely my superior in every single moral quality, consented to be my wife. She has been my wise adviser and cheerful comforter throughout life, which without her would have been during a very long period a miserable one from ill-health. She has earned the love of every soul near her." XLIII ANECDOTES OF HUXLEY Huxley was more than one of the greatest scientists of the last century; he was a man of literary ability. By his popular lectures and clear expositions he probably did more than any other man of the century to popularize the many and important discoveries of the scientific world. At first there was much opposition to him, owing to a lack of information on the part of the public as to the import of the doctrine of evolution. Ex-President Gilman of Johns Hopkins University tells what a storm of protest was raised in America when Huxley was invited to deliver the opening address at the founding of the new university. Huxley is not even now regarded as an orthodox man, but much of the former prejudice has given way.
