[The record of work includes his volume on 'Coral Reefs' (A notice of the Coral Reef work appeared in the Geograph. Soc. Journal, xii., page 115.), the manuscript of which was at last sent to the printers in January of this year, and the last proof corrected in May. He thus writes of the work in his diary:--
"I commenced this work three years and seven months ago. Out of this period about twenty months (besides work during "Beagle's" voyage) has been spent on it, and besides it, I have only compiled the Bird part of Zoology; Appendix to Journal, paper on Boulders, and corrected papers on Glen Roy and earthquakes, reading on species, and rest all lost by illness."
In May and June he was at Shrewsbury and Maer, whence he went on to make the little tour in Wales, of which he spoke in his 'Recollections,' and of which the results were published as "Notes on the effects produced by the ancient glaciers of Caernarvonshire, and on the Boulders transported by floating Ice." ('Philosophical Magazine,' 1842, page 352.)
Mr. Archibald Geikie speaks of this paper as standing "almost at the top of the long list of English contributions to the history of the Ice Age." (Charles Darwin, 'Nature' Series, page 23.)
The latter part of this year belongs to the period including the settlement at Down, and is therefore dealt with in another chapter.]
