Provides JH with the measurements from a series of observations of Gamma Virginis.
Refers to a variety of salts and their reaction to light in the production of photographs. JH hopes that [?] still intends to publish his work in this area.
Will undertake magnetic report except parts for which research is not yet completed. Needs [Johann] Lamont's recommendation regarding experiments. Sends [James] Ross's observations for perusal.
Finds GA's measurements of Gamma Virginis far away from JH's own, and instructs GA in the best way to measure double star positions.
Devises and suggests mode of micrometric measurement of angles.
Pleased with JH's Gamma Virginis results. Mr. Visconti made head of Military Geographical Institute at Naples.
Sends calculations of Gamma Virginis and determines its eccentricity. Believes the orbit is highly elongated, like that of a comet.
Agrees with JH opinions of Gamma Virginis orbit. Sends JH a drawing by C. P. Smyth of Halley's Comet.
Regarding the measurement of angles. Observations on a problem set by JH.
Since he forwarded the parcel he has changed his address.
Has received the maps. Gives F. W. Bessel's views on the re-arrangement of the constellations which has been proposed. Comments on FB's memorandum.
Is returning the report to the B.A.A.S., with one alteration. Will forward the map to Mr. Jensen with JH's remarks.
Will be unable to attend the meeting of the B.A.A.S. His sister is having an operation to her eyes. Is sending an account of the comet. Mr. Jensen will be coming down with the map.
Mr. Jensen called to say that he will be visiting Collingwood on Monday with the map.
Comments on calculation of orbit of Gamma Virginis; requests any observations EC has of that star.
Received copies of barometer observations. Searching for original data (lists stations) that JH sent to WB. Invites additions to JH's report. Please send account of expenses.
Yesterday's letter was mistakenly sent to WB's former address. Sends copy.
JH's theory of barometric waves. Comparison with ocean tides. Non-trade winds follow laws of periodicity and are predictable, accounting for previously unexplained phenomena. Attributes rotating storms to interference of two or more wave trains. Will propose WB as director of new B.A.A.S. project to discover laws of weather behavior. Sends payment for WB's expenses. Never saw anything more beautiful than WB's 'Symmetrical Barometric Curve.'
Declines WP's invitation to attend Cork B.A.A.S. meeting and afterwards to visit WP and to see his reflecting telescopes. Informs WP that [C. A. von] Steinheil had written JH about a process of 'Electro-gilding' mirrors for telescopes.
Regarding a nuisance created at Slough by a steam engine.
