Received prospectus of Kew observatory. Its objectives seem incompatible. It appears better suited as experimental institution. Refer Francis Beaufort to JH's 11 Oct. 1835 letter to Beaufort defining physical observatories.
Received WB's atmospheric curves yesterday, but too late to report them [at 1842 B.A.A.S. meeting]. Final report will be presented at next [1843] meeting.
Reviews WB's assistance in JH's meteorological investigations as testimonial on behalf of WB's application for position of curator at Kew Observatory.
Offers to meet FB at Manchester B.A.A.S. meeting and to bring FB to Collingwood for a quiet visit.
Alerts WW that F. W. Bessel, in very poor health, will attend the Manchester B.A.A.S. meeting. JH plans to bring Bessel to Collingwood after the meeting.
Has stayed in Manchester an extra day, and has managed to avoid becoming involved in the organization of next year's B.A.A.S. meeting at Cork; talks about plans for F. W. Bessel to visit Collingwood, and about JH's plans to return home.
JDH writes to Charles Lyell about specific points of geological interest encountered on the Ross Antarctic Expedition. Thanks Lyell for giving him Darwin's book with a description of Cape Verde. Also says he values THE GEOLOGICAL RESEARCHER & the profile of Lyell, which he keeps in his cabin with his father & Baron Humboldt's. Describes the Geology of Kerguelen Island & compares it to the account of Captain Cook who knew it as Desolation Island. Rocks incl: Trass, lava, Breccia, whinstone, volcanic conglomerations, basalt configurations, Quartzes & Zeolites. McCormick sent back fossil woods. Letter includes a sketch of Christmas Harbour. Birds incl: endemic Chionis & night Petrel. 3 insects: a Curculio, apterous moth & a spider. Describes the Kerguelen climate. Found more plants than expected: seaweeds, lichens, Mosses & Jungermannia, all perennial South American types. Writes about icebergs near Kerguelen & refers to the theory of erratic boulders which Charles Lyell's son has written about. Describes an agate fossil trunk he found in Van Diemen's Land & his notes on it in TRANSACTIONS OF THE NATURAL HISTORY SOCIETY OF TASMANIA. The Auckland Island flora resembles that of New Zealand. Describes icebergs, first seen at latitude 63 degrees south. At 66°S collected black volcanic rock containing Olivine from an iceberg, which is illustrated. Describes mountainous land mass at 71°S & an island with a penguin rookery. Dredging to 300 fathoms found marine life: chiefly Mollusca, Crustacea, Corals, Bicellaria, some Ophiura & Syenite rock deposited by an ice berg. On an island 76°S observed signs of the different natural means of rock transportation & land formation. Includes a sketch of the ship 'Erebus' anchored off this island's cliffs. Describes discovery of the volcanoes 'Erebus' & 'Terror' incl. sketch. Discusses abundance of Diatoma found in the tow net & stomachs of Salpa & his belief that it is vegetable not animal. JDH has a geological collection for Lyell Jnr.
JDH informs Ward that the expedition was unable to go to Chatham Islands so he could not get Hypnum Menziesii for Ward. There are very few botanical discoveries to be made in the extreme south latitudes. The wealth of marine animals suggests there should be corresponding plant life but JDH has only found 1 sea plant within Antarctica; a Diatoma. He has found vegetation beyond the previous southern extreme of known plants: Deception Island. He discusses these southerly marine plants: Sargassum natans, Macrocystis pyrifera & a Laminaria brought on currents from New Zealand & propagated at sea by marine animals. The distribution & character of the latter is described at length. Recounts his study of the new Antarctic Diatoma identical to confervoid remains found in fossil powders, & his study of New Zealand mosses incl. a long description of the development of Theca based on dissections of Orthotichum, Dawsonia & Polytrichum & Sclotheimia sp. In general his conclusions agree with Valentine's. His description incl. detailed speculation on Sporule formation, the anatomy of the columellar e.g. in a new species of Entosthodon from Bay of Islands & in other Funaria, & the teeth which connect the peristome to the theca e.g. in Schistostega & Syrrhopodon compared to Syrrhopodon & others. His observations suggest that the distinction of genus Codonoblepharum based on its cone shaped membrane is erroneous. Quotes from his notes on a Campbell Island moss. Speculates on the nature of the annulus. Touches on the mystery of sexes in mosses. States that all this anatomical investigation should aim toward a natural arrangement of mosses, hitherto hampered by ignorance re. geographical distribution & habit. Under date 21 June records his observations on the anatomy of an Orthotrichum & a Sphagnum, incl sketches. Under date July 21 describes: dissection of Voitia, with reference to Brown's description from Parry's Voyage, also the drumhead of Polytrichnum, both incl. illustrations.
