Suggests CD go to Geological Society, present himself, as AS's friend, to William Lonsdale and study the Society's collection.

Ramsay's death a grievous loss.
Before this you will have received a letter I addressed to you, some time since, at
Shrewsbury. It contained a statement of what I was doing & had done— I
have now resolved to confine myself to this county, & if I can finish it to my
satisfaction I shall be well content to turn my back on these mountains for a
season— I cannot but be glad at your appointment & I truly hope it
will be a source of happiness & honor to you.— I really dont know what

- f1 129.f1Sedgwick probably refers to Daubeny 1826 as particularly relevant to South American geology. A much spotted copy in Darwin Library--Down may be the one CD had on board the Beagle (see Correspondence vol. 1, Appendix IV). A pencil drawing of volcanic islands in the section on the Azores (p. 26) and a note `Covington Copy' next to a footnote on trachyte (p. 180) are more characteristic of notes CD made later while at work on the geology of the voyage.
- f2 129.f2Jean François d'Aubuisson de Voisins.
- f3 129.f3Abraham Gottlob Werner formulated the so-called Neptunian hypothesis that the rocks of the earth's crust were formed by depositions from a global ocean. It is not clear whether Sedgwick refers to Aubuisson's An account of the basalts of Saxony (1814) or to his two-volume more general geological work, the Traité de géognosie (1819), in which Aubuisson modified his Neptunism, though not his admiration of Werner as a founder of the science of geology. Both volumes are in Darwin Library--CUL. The Traité's title-page bears the inscription `C. Darwin HMS Beagle' and has many more annotations than the Account. CD refers to it frequently in his geological notes during the voyage. There is no evidence that CD also had the Account on board.

- f9 129.f9Sedgwick reported on the geology of North Wales to the Cambridge Philosophical Society on 11 March 1833. An abstract was published in the Philosophical Magazine 2 (1833): 381. His major finding was that `the strata of that district are bent into saddles and troughs, of which the anticlinal and synclinal lines occur alternately, and are all nearly parallel to the ``great Merionethshire anticlinal line.''
