To J. de C. Sowerby 19 February 
Down Farnborough Kent
Feb. 19th —
My dear Sir
The Plate will now do very well;1 & I am much obliged for all the trouble you have taken, & congratulate you that I can cause no more.
The specimens all arrived quite safe: I thank you for having registered them which I did not think of, & I return you in stamps the Cost.—
With respect to what you say about the payment of the drawings is exceedingly liberal; but on the other hand, the drawings, though no doubt they facilitated the engraving, must have put you to some extra trouble; did you include this trouble in your estimate to the Pal. Soc.? because if not, I must beg you, to make some charge to me, for I should be sorry to take an unfair advantage of your liberality. On the latter view, whenever convenient, please to let me know what I am indebted to you.
Accept my thanks & believe me | Yours very faithfully | C. Darwin
P.S. | Mr Salter2 tells me you have several named fossil Balani; if you could at any time get to these & lend them me, they might & probably would be of great service.3
Comments on JdeCS’s plates [for Fossil Cirripedia (Lepadidae)]. Asks if JdeCS can lend him specimens of fossil Balanidae.
