The On'i^in of Species was published, and the whole 

 of the 1,250 copies sold, on November 24, 1859. An 

 advance cop\ had been sent b)- Darwin to the 

 friend whose opinion he was so extremely anxious to 

 learn. ' I shall be itiioisely curious to hear what effect 

 the book j^roduces on )'ou,' he wrote on October 15.^ 

 Huxley replied on November 23 that he had finished the 

 Origm on the previous day. He wrote of ' the great 

 store of new views ) ou have given me ' : - and in his 

 chapter On the Reception of the Orio^in of Species, he 

 says, ' my reflection, when I first made myself master of 

 the central idea of the " Origin" was, " How extremely 

 stupid not to have thought o^ that !" '"^—-further evidence 

 that he knew nothing of the subject of the Linnean Societ\ 

 memoir, where this central idea is admirably, although of 

 course briefly, set forth and illustrated b\' its two great 

 discoverers. 



Huxley's ignorance of Natural Selection between July 

 I, 1858, and the end of November, 1859, suggests certain 

 interesting conclusions. Great and original workers rarely 

 have the time for wide reading in their subject away 

 from the lines of their special investigations. But want 

 of time is not the only cause. They are, perhaps 

 unconsciously, led by an instinct which warns them that 

 the attempt to be encyclopaedic, though within the limits 

 of but a single science, is itself destructive of originality. 

 And yet there is nothing so inspiring to a young worker 

 as the fact that his attempts have interested a great leader 

 in his own subject. To a Darwin at the age of fifty, it 

 ma)' be a small thing that his younger friend is too 

 engrossed to read his paper, and )et many years before 

 we know that even Darwin keenly felt the neglect, as it 

 appeared to be, of his early geological work. Thus he 

 wrote in 1844 or 1845: 'I have long discovered that 

 geologists never read each other's works, and that the
