" The value of the Cirripede monograph lies not merely in the fact 

 that it is a very admirable piece of work, and constituted a great addition 

 to positive knowledge, but still more in the circumstance that it was a piece 

 of critical self-discipline, the effect of which manifested itself in everything 

 your father wrote afterwards." T. H. Huxley to F. Darwin, 1887. 



" One result was that he would never allow a depreciatory remark to 

 pass unchallenged on the poorest class of scientific workers, provided that 

 their work was honest, and good of its kind. I have always regarded it as 

 one of the finest traits in his character, — this generous appreciation of the 

 hod-men of science, and of their labours... and it was monographing the 

 Barnacles that brought it about." Sir J. D. Hooker to F. Darwin, 1887. 



1856 "Early in 1856 Lyell advised me to write out my views pretty fully, 



and I began at once to do so on a scale three or four times as extensive 

 as that which was afterwards followed in my Origin of Species." 



1858 Joint paper by Charles Darwin and Alfred Russel Wallace " On the 

 Tendency of Species to form Varieties ; and on the perpetuation of Varieties 

 and Species by Natural Means of Selection," communicated to the Linnean 

 Society by Sir Charles Lyell and Sir Joseph Hooker. (Read July 1.) 



" I was at first very unwilling to consent [to the communication of his 

 MS. to the Society] as I thought Mr Wallace might consider my doing so 

 unjustifiable, for I did not then know how generous and noble was his 

 disposition." 



1859 Nov. 24. Publication of The Origin of Species (1250 copies). 



" I never even built a castle in the air of such success as it has met 

 with ; I do not mean the sale, but the impression it has made on you (whom 

 I have always looked at as chief judge) and Hooker and Huxley. The whole 

 has infinitely exceeded my wildest hopes." From a letter to Lyell, 1859. 



" I have received your kind note and the copy ; I am infinitely pleased 



and proud at the appearance of my child You are really too generous to 



me about the, to me, scandalously heavy corrections. Are you not acting 

 unfairly towards yourself?" From a letter to Mr John Murray, 1859. 



" The most potent instrument for the extension of the realm of natural 

 knowledge which has come into men's hands, since the publication of 

 Newton's ' Principia,' is Darwin's 'Origin of Species.'" Huxley, 1887. 



" The oldest of all philosophies, that of Evolution, was bound hand 

 and foot and cast into utter darkness during the millennium of theological 

 scholasticism. But Darwin poured new life-blood into the ancient frame ; 

 the bonds burst, and the revivified thought of ancient Greece has proved
