My dear Forchhammer

I ought to have written sooner to have thanked you very sincerely for your letter of the 27th of April: it told me quite fully & most clearly, all that I wanted to know of your Geology.

Prof. Steenstrup's specimen which I owe first to your kindness have been of great use & interest to me: I have now described 33 fossil Pedunculated Cirripides, & they are in Mr Sowerby's hands to make drawings of.—

With my very sincere thanks | Believe me | Yours very truly | Charles Darwin

    The letter has not been found. The geological information may have been in answer to letter to J. J. S. Steenstrup, 3 April [1850], asking about the relationship of the chalk formations of Scania, Faxoe, and Westphalia. In Fossil Cirripedia (1851): 7, CD cited Forchhammer and Steenstrup as his authorities for considering them equivalent formations, more recent than the common Upper or White Chalk and equivalent to the formation of Maastricht.
