Ejntome of Charles DarwivUs Life xv 



1842 " In June 1842 I first allowed myself the satisfaction of writing a very brief 

 abstract of my [species] theory in pencil in 35 pages ; and this was enlarged 

 during the summer of 1844 into one of 230 pages, which I had fairly copied 

 out and still [1876] possess^." 

 Sept. 14. Settled at the village of Down in Kent. 

 "I think I was never in a more perfectly quiet country." 

 Publication of The Structure and Distribution qf Coral Reefs ; being Part I. 

 of the Geology of the Voyage of the Beagle. 



1844 Publication of Geological Observations on the Volcanic Islands visited during 



the Voyage of H.M.S. Beagle; being Part II. of the Geology of the Voyage 

 of the Beagle. 

 " I think much more highly of my book on Volcanic Islands since Mr Judd, by 

 far the best judge on the subject in England, has, as I hear, learnt much 

 from it." [Autobiography, 1876.] 



1845 Publication of the Journal of Researches as a separate book. 



1846 Publication of Geological Observations on South America ; being Part III. of 



the Geology of the Voyage of the Beagle. 



1851 Publication of a Monograph of the Fossil Lepadidae and of a Monograph of 

 the sub-class Cirripedia. 

 " I fear the study of the Cin-ipedia will ever remain ' wholly unapplied,' and 

 yet I feel that such study is better than castle-buildiug." 



1854 Publication of Monographs of the Balanidae and Verrucidae. 



" 1 worked steadily on this subject for... eight years, and ultimately published 

 two thick volumes, describing all the known living species, and two thin 

 quartos on the extinct species... .My work was of considerable use to me, 

 when I had to discuss in the Origin of Species the principles ot' a natural 

 classification. Nevertheless, I doubt whether the work was worth the 

 consumption of so much time." 



" From September 1854 I devoted my whole time to arranging my huge pile of 

 notes, to observing, and to experimenting in relation to the transmutation of 

 species." 



1856 " Pearly 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," counnunicated to the Linnean 

 Society by Sir Charles Lyell and Sir Joseph Hooker. 



"I was at first very unwilling to consent [to the comnmiiioation of his MS. to 

 tlio Society] as 1 thought Mr Wallace might consider my doing so unjustifi- 

 able, for I did not then know how generous and noble was his disposition." 



"July 'JO to Aug. 12 at Sandown [Isle of Wight] began abstract of Species 

 book." 



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



"Oh, good heavens, the relief to my head and body to banish the whole 

 subject from my mind !...But, ala.s, how frcqiioiit, how almost univcr.>;:il it is 

 in an author to persuade hini.scirof tlie truth of iiis (twn dogmas. My only 

 hope is that I certainly see many difficulties of gigantic stature." 



' Tho first draft of The Origin of Species, edited by Mr Francis Darwin, will bo 

 publiBhed this year (1909) by the Syndics of the Cambridge University Press.
