CHARLES DARWIN. 85 



I cannot give here even an epitome of the Ongi?i of Species 

 (1859), the Variations of Anifuah and Plants under Domesti- 

 cation^ or the Descent of Man (187 1), all three of which 

 books are more or less zoological ; to the second of these I briefly 

 referred under the head of Botany ; neither can I go further than 

 to say that we find the marks of Darwin's genius not only in the 

 three sciences already named, but also in that of 



Psychology. — His book entitled The Expression of the 

 Emotio?iSy published in 1872, together with a single chapter in 

 the Origi?i of Species and three in the Descent of Man^ are all 

 nearly related to this science. To these we must add what I 

 believe w^as his last-written paper, published in Alind, on the 

 Psychogenesis of a Child, an Essay on Infantile Intelligence. 



I have said enough to show the wide-reaching grasp of his 

 mighty intellect and the debt that all the world of sciences owes 

 to his labours. 



Regarding his greatest work. The Origin of Species, and 

 that which twelve years afterwards followed it, The Descefit of 

 Man, I need only say a few words. For the most admirable and 

 masterly epitome and exposition of these books I refer any of you 

 to the lately-issued volume, ' Charles Darwin,' by Grant Allen, 

 forming the first of ' English Worthies.' Pages 58-143 of this 

 beautiful tribute to Darwin's memory will charm every reader of 

 them. 



We are all more or less familiar with the story of the Origi?t 

 of Species. The " idea " of the work occurred to Darwin in 

 1837. After five years' collecting of facts, ht "allowed himself to 

 speculate on the subject, and drew up some short notes;" in 

 1844 he enlarged these into " a sketch of probable conclusions ;" 

 from then up to 1859 he " steadily pursued the same subject." 

 Twenty-two years did Darwin wait before he ventured to send 

 forth his epoch-making book ! And yet the Quarterly Review, by 

 way of a monstrous perversion of truth, charged him with " a con- 

 tinually growing neglect of the facts around him ;" and the Edi?i- 

 burgh Review warned the members of the Royal Institution (who 

 had listened to Huxley's favourable lecture on the book) against 

 such " abuse of science " ! 



The immediate cause of the issue of the book must not be
