Asks for seeds and roots of native plants of the Cape. Refers to JH's writings on beating of the heart and comments on some optical experiments of Charles Wheatstone and David Brewster.

Will write [J.-B.] Biot, but does not know to which enquiries Biot wishes JH to respond. Also wants to thank Biot for his kindness. S.-D. Poisson in a statement before the Académie des sciences has misdescribed JH's planned voyage.
The observational data from FS regarding Gamma Virginis are so significant that JH begs FS to continue to observe and send JH the results. Comments on a number of other astronomical observational matters.
Concerned about payment for instruments. Has read in newspaper that JH is preparing to study the southern hemisphere. Asks to keep in touch. Will soon go to Paris for transit instrument and another publisher for the translation of JH's work. Problems on account of Revolution.
JH preparing for his journey to Cape Town. Compiling a catalog of nebulae and clusters. Sending to CH a comparison of a new set of elements of Gamma Virginis and a set of observations of it from 1720-1833; JH asks CH to send a copy to Carl Gauss.
Gently rejects MP's offer to accompany JH to the Cape to act as JH's assistant. JH claims the voyage to be a 'pure family party of pleasure,' and if astronomy can not be well practiced at the Cape, the family may go on to India to visit the relatives of JH's wife, Margaret.
Praises JH's Prelim. Discourse and work in general. Wishes well at the Cape.
Thanks JH for clues to interesting star 'near Eta Coronae.' Sends sketches of April [1832?] observations of nebulae.
Comments on JH's paper on potash in Annales de chimie. Has observed reaction products in microscope. Concerned over delay in publication by David Brewster of his experimental results in optics and light, especially as WT not convinced of legitimacy of rumored results.
Account of the four-month voyage to Tierra del Fuego, Cape Horn, and return. The Fuegians are landed with Richard Matthews [the missionary in charge of them]. Storms, seasickness, hostile savages, and scenery are described. His increasing interest in all branches of natural history makes the hardships worth while. FitzRoy buys a schooner. CD will stay at Rio Negro while it is fitted.
Feeling simply 'dismal.'

Has received payment from [John] Murray [for review of Mary Somerville's Mechanism of the Heavens ?]. Cannot answer Mrs. Somerville's question about poles of maximum cold.
Sends on a copy of JH's orbital elements for Gamma Virginis.

Thanks EC's for EC's observations made with EC's excellent telescope. Discusses Eta Coronae, Gamma Virginis, EC's drawing of M51, and whether Orion changes, stating that JH is 'no believer in rapid changes in Nebulae yet there may be changes....'
