My dear Lyell
I am writing to you in order to answer Lady Lyells note to Emma,—as she find writing or indeed doing anything whatever a considerable exertion.
We have been most sincerely grieved to hear such very indifferent accounts of

I wish I could see you sooner than I shall, for I

I am working very steadily at my big Book;—I have found it quite impossible to publish any preliminary essay or sketch; but am doing my work as complete as my present materials allow, without waiting to perfect them. And this much acceleration I owe to you.
I know you like all cases of negative geological evidence being upset. I fancied that I was a most unwilling believer in negative evidence; but yet such negative evidence did seem to me so strong that in my Fossil Lepadidæ I have stated, giving reasons, that I did not believe there could have existed any Sessile Cirripedes during the Secondary ages. Now the other day Bosquet of Maestricht sends me a perfect drawing of a perfect Chthamalus, (a recent genus) from the Chalk! Indeed it is stretching a point to make it specifically distinct from our living British Species.— It is a genus not hitherto found in any Tertiary bed.
Farewell | Yours most truly | C. Darwin

Lyell had been working for several years on an analysis of the volcanic geology of Madeira and intended to publish a paper in collaboration with Georg Hartung (see K. M. Lyell ed. 1881, 2: 232, 282). The paper was eventually abandoned, but Hartung later published most of their results (Hartung 1864). - +

Lyell had urged CD to publish a short sketch of his theory in order to establish his priority (letter from Charles Lyell, 1–2 May 1856). - +
