With thanks for ED’s publication. "I consider your having made my work known in Germany a full & ample recompense to such exertions as I made during our Voyage".

Thanks ED for copy of German edition of Journal of researches. Asks him to write and ask German publisher to return plates and MS.

"It is evident that you have not time now to pay me a visit, & indeed as Mrs Darwin is in daily expectation of her confinement I could hardly have asked you … When I saw your name & that of many other naturalists at Cambridge, I wished much to have been there; but my strength so often fails me, that I expected more mortification than pleasure …

I should have liked to have heard the Crater-of-Elevation discussion; after having read both sides, I cannot subscribe to that view; but I think there remains something unexplained about those many vast circular volcanic ruins …

I presume it is very unprobable [sic] that there will ever be a second German Edition of my Journal … I have largely condensed, corrected & added to the Second English Edition, & I am sure have considerably improved & popularised it".
