My dear M^r Murray,

I am sorry to have caused trouble about the £1–16 by my blunder.¹

As I said I am not sanguine about the sale of the little book, but success apparently depends largely on chance; and it appears to me fair that if above 1500 copies should be sold that I should receive $\frac{2}{3}$ profits as on former occasions.² I am bound to look after D^r Krause’s³ interest (as well as my own) and unless you feel inclined to agree to my proposal, I should prefer publishing on commission, or taking the proof sheets to Mess^rs Macmillan⁴ to see if they will give me larger profits. Do you offer books published on commission at your sale to the booksellers, which I suppose is an advantage? I omitted to state that I shall have pay M^r Dallas for translating, and he has translated a good deal more of Krause’s MS than appears to me worth publishing.⁵

A picture of D^r Darwin has been photographed by the Autotype C^o, & there only remains to strike off copies, and to ascertain the price per thousand.⁶

Yours sincerely | Ch. Darwin
