Henslow informs me that Sedgwick (Sedgwick's address is given somewhat abbreviated in "The Cambridge Chronicle", May 19th, 1860.) and then Professor Clarke [sic] (The late William Clark, Professor of Anatomy, my father seems to have misunderstood his informant. I am assured by Mr. J.W.
Clark that his father (Prof. Clark) did not support Sedgwick in the attack.) made a regular and savage onslaught on my book lately at the Cambridge Philosophical Society, but Henslow seems to have defended me well, and maintained that the subject was a legitimate one for investigation. Since then Phillips (John Phillips, M.A., F.R.S., born 1800, died 1874, from the effects of a fall. Professor of Geology at King's College, London, and afterwards at Oxford. He gave the 'Rede' lecture at Cambridge on May 15th, 1860, on 'The Succession of Life on the earth.' The Rede Lecturer is appointed annually by the Vice-Chancellor, and is paid by an endowment left in 1524 by Sir Robert Rede, Lord Chief Justice, in the reign of Henry VIII.) has given lectures at Cambridge on the same subject, but treated it very fairly. How splendidly Asa Gray is fighting the battle. The effect on me of these multiplied attacks is simply to show me that the subject is worth fighting for, and assuredly Iwill do my best...I hope all the attacks make you keep up your courage, and courage you assuredly will require...
CHARLES DARWIN TO A.R. WALLACE.
Down, May 18th, 1860.
My dear Mr. Wallace, I received this morning your letter from Amboyna, dated February 16th, containing some remarks and your too high approval of my book. Your letter has pleased me very much, and I most completely agree with you on the parts which are strongest and which are weakest. The imperfection of the Geological Record is, as you say, the weakest of all; but yet I am pleased to find that there are almost more geological converts than of pursuers of other branches of natural science...I think geologists are more easily converted than simple naturalists, because more accustomed to reasoning.
Before telling you about the progress of opinion on the subject, you must let me say how I admire the generous manner in which you speak of my book.
Most persons would in your position have felt some envy or jealousy. How nobly free you seem to be of this common failing of mankind. But you speak far too modestly of yourself. You would, if you had my leisure, have done the work just as well, perhaps better, than I have done it...
...Agassiz sends me a personal civil message, but incessantly attacks me;but Asa Gray fights like a hero in defence. Lyell keeps as firm as a tower, and this Autumn will publish on the 'Geological History of Man,' and will then declare his conversion, which now is universally known. I hope that you have received Hooker's splendid essay...Yesterday I heard from Lyell that a German, Dr. Schaaffhausen (Hermann Schaaffhausen 'Ueber Bestandigkeit und Umwandlung der Arten.' Verhandl. d. Naturhist. Vereins, Bonn, 1853. See 'Origin,' Historical Sketch.), has sent him a pamphlet published some years ago, in which the same view is nearly anticipated; but I have not yet seen this pamphlet. My brother, who is a very sagacious man, always said, "you will find that some one will have been before you."I am at work at my larger work, which I shall publish in a separate volume.
But from ill-health and swarms of letters, I get on very very slowly. Ihope that I shall not have wearied you with these details. With sincere thanks for your letter, and with most deeply felt wishes for your success in science, and in every way, believe me, Your sincere well-wisher, C. DARWIN.
CHARLES DARWIN TO ASA GRAY.
Down, May 22nd 1860.
