MEMOIR. lxili 
To which Bates replied as follows :-— 
‘22, HARWOOD STREET, HAVERSTOCK HILL, N.W., 
“* May 2nd, 1863. 
‘*My DEAR MR. DARWIN, 
**T have received both your letters containing remarks on my book, 
and need not say how well satisfied I feel with them. From all quarters, 
strangers and friends, the opinions are favourable. It is most curious: all 
find pleasure in the book, Darwinians, Calvinistic church ministers, Dissenting 
parsons, hard-headed men of business; women, old men and boys; philo- 
sophic naturalists and species grubbers. It makes one feel contented to be 
the author on the score of literary form alone, but more substantial rewards 
are not wanting, for Mr. Murray has given me a handsome sum (£250); 
although the edition (1250) is far from sold out. He has behaved in the most 
friendly manner to me, the friendliness visibly increasing every day. 
“‘T cannot forget that all this is due primarily to yourself, who gave me so 
favourable an introduction to a publisher. Not only that, if it had not been 
for your spurring me on I am quite sure the book would never have been 
written. As long as I live I shall remember these things, and wish it were 
within the limits of etiquette to make them public. Murray said to me on 
Wednesday, ‘I am very glad I am the publisher of the book.’ 
*‘Your former letter, in which was a quotation from a letter of Asa Gray’s, 
gave me much pleasure. I find there is no end to the instruction that may be 
drawn from these cases of mocking butterflies; every time I reflect on them 
some new deduction flows forth, so that I think I have matter enough for 
another paper, which might be illustrated by the same plates. Mr. Wallace 
came last Sunday to spend the evening with me, and after examining all my 
specimens of these mockers, came to the conclusion that all nature does not 
furnish so plain and striking a case of the origin of species, and of new and 
complex adaptations to new conditions, by the simple process of variation and 
natural selection. But my first task will be to write a paper on the general 
subject of origin by segregation of local races. 
‘* Believe me, yours sincerely, 
“H.W. BATES” 
The notices of the book were as appreciative as its author could 
expect or desire. The easy and luminous style, the vividness and, 
withal, sober exactness of the descriptions, the air of veracity, of real 
but never obtruded knowledge throughout, imparted a fascination 
to which every review, save that of the Athengum, jealous of its 
ancient v6le of advocatus diaboli, paid just tribute. The following 
extract from the lengthy notice which appeared in the Revue des 
Deux Mondes may be taken as a fair specimen of the rest :— 
‘* Without dwelling on the special interest which attaches to Mr. Bates’s 
discoveries, it is easy to show by a few quotations that the phenomena which 
+he describes speak to the imagination of every man, scientific or not, to
