I am EXTREMELY glad to hear that you approved of my cirripedial volume. I have spent an almost ridiculous amount of labour on the subject, and certainly would never have undertaken it had I foreseen what a job it was. I hope to have finished by the end of the year. Do write again before a very long time; it is a real pleasure to me to hear from you. Farewell, with my wife's kindest remembrances to yourself and Mrs. Fox. My dear old friend, yours affectionately, C. DARWIN. CHARLES DARWIN TO W.D. FOX. Down, August 10th [1853]. My dear Fox, I thank you sincerely for writing to me so soon after your most heavy misfortune. Your letter affected me so much. We both most truly sympathise with you and Mrs. Fox. We too lost, as you may remember, not so very long ago, a most dear child, of whom I can hardly yet bear to think tranquilly; yet, as you must know from your own most painful experience, time softens and deadens, in a manner truly wonderful, one's feelings and regrets.

I then opened yours, and such is the effect of warmth, friendship, and kindness from one that is loved, that the very same fact, told as you told it, made me glow with pleasure till my very heart throbbed. Believe me, I shall not soon forget the pleasure of your letter. Such hearty, affectionate sympathy is worth more than all the medals that ever were or will be coined. Again, my dear Hooker, I thank you. I hope Lindley (John Lindley, 1799-1865, was the son of a nurseryman near Norwich, through whose failure in business he was thrown at the age of twenty on his own resources. He was befriended by Sir W. Hooker, and employed as assistant librarian by Sir J. Banks. He seems to have had enormous capacity of work, and is said to have translated Richard's 'Analyse du Fruit' at one sitting of two days and three nights. He became Assistant-Secretary to the Horticultural Society, and in 1829 was appointed Professor of Botany at University College, a post which he held for upwards of thirty years. His writings are numerous: the best known being perhaps his 'Vegetable Kingdom,' published in 1846. His influence in helping to introduce the natural system of classification was considerable, and he brought "all
