Reports conflicting observations of Gamma Virginis. Uses JH's method of measuring double star positions.

Regarding the Brisbane Catalogue. JH's discoveries relating to the moon. The James South lawsuit still hangs on. Is about to depart for Scotland. W. S. Stratford has finished his ephemeris of Halley's Comet.

Asks TM to accompany himself and Daniel Cloetes in hunting a leopard.

Mural and transit are at JH's command. Will have pleasure in joining him on Saturday. Has a good supply of balls and will procure some goose shot.

Comments on communications with the Cape. James Stewart (Margaret Herschel's brother) is well liked by the family. GP is sending on his meteorological observations, noting that he has reduced his emphasis on astronomy. Is working on a long memoir on integral calculus. [Many parts of the letter are illegible.]

Received his last letter regarding Alpha Virginis in time to read it at the council. Has sent him all Stratford's Ephemerides. Regarding the sounding of the Brazil Banks. Back goes to Wager River the first week in June.

Discusses observations of Mt. Etna since its last eruption in 1832 and the work of geologist Teodoro Monticelli.

Has been busy correcting proofs of a little book to be printed by Cadell in Edinburgh which has occasioned the delay. Observed the eclipse at the Observatory with D. F. J. Arago. Comments on the work of Arago. French science and literature at a low ebb.

Wonders if people at the Cape observed the large fall of meteors during the night of 12 Nov. 1833; comments on this and gives theories of one professor. JH's name was used for newspaper article on discoveries on the moon; the person responsible was R. A. Locke. Encloses one of his own memoirs on the eclipse.

Does not want to compute precessions for each individual star.

Has asked Dr. Andrew Smith, Capt. J. E. Alexander, and their friends for Saturday; hopes JH can join them. Has recognized fifteen of the November cometary stars; they are in Harding's map with one exception. The Ephemeris will require a small correction.

Is proceeding at a respectable speed with the Brisbane list. Has received [Andrew?] Smith's box safely. Saw Dr. Smith last night; he is more reconciled. Many thanks for the trees; the ground is suitable to receive them.

Thanks WS for having accepted his medal from R.A.S. Finds that the [Thomas] Brisbane Catalogue contains insufficient right ascension information, complicating reduction observations. Observed Halley's Comet.

Preparing fifth edition of Principles of Geology, using JH's facts about boiling seeds. Mathematical error in CL's climate theory. CL's first speech as president of Geological Society. Criticizes R.S.L. JH's volcanic theory was too complex; will incorporate it into later editions. Benefits to science of Charles Babbage's social parties. Latest publications in geology. P.S. Glad to learn that JH thinks origin of new species may occur through intermediate causes; Germans criticized this. CL chooses not to engage in controversies. Speculates on successive extinction of species. Notes on African hot springs.

Believes the wires are 0.2" thicker than the old ones. Dust has settled on the parallel wires of the telescope. Advises how adjustment may be made to JH's micrometer for parallelism.

Has returned the drawings to [Andrew?] Smith not having received carte blanche to look at them. Bent one of the thick wires of the micrometer when taking out the plate, so has inserted another. The micrometer will be ready tomorrow. Clean Bermuda webs and two silver wires of 6" diameter.

Thanks TM for restoring JH's micrometer.

Charles Lyell wrote letter to JH recently. Now encloses with it letters of introduction to persons in Rio and abstract of paper by Charles Babbage. [Henry] Brougham's attacks on Thomas Young.

WW's results regarding tidal observation and theory. Requests further data from the Cape. Has nearly completed his history of the inductive sciences.

Is enclosing some accounts of the eclipse of the sun. The St. Helena instruments have arrived. Some observations are going to be made in Upper Canada. G. B. Airy proposes some extensive magnetic observations at Greenwich. Is going to Greenwich to see and plan extension to the observatory.
