To William Lonsdale [15 May 1838]
My dear Lonsdale
I return my paper.—1 I have put a few pencil notes on the margin, which will explain to the referee, how much I intend modifying certain portions.— The whole I find requires a good deal of clarifying & polishing.
I returned from Cambridge last night.— I found Sedgwick very well & in high spirits, & therefore the sooner my paper goes to him the better.—
I have been looking over parts of Hopkin’s paper.2 I find in the latter part he refers to the diagram (No. 1. of mine)3 as a really possible section of a mountain chain, which, after what you pointed out to me, appears to me, clearly to be an inaccuracy on his part, although not of essential consequence. I shall get myself into a dilemma, with these sections, if I do not take good care.
I wish it was not too late to modify the title 〈of〉 the paper, as I have put it in pencil but that, I suppose, is altogether impossible.—4
Yours most truly | Chas. Darwin Tuesday Morning
