Is enclosing two transcripts of letters from William Simms relating to the object-glass. a. Hopes to give account next week. b. One glass good, other has failed.
Regarding the acceleration of retention of a shrinking sphere.
Has been with Philip Melvill of the East India Co. discussing the printing of the observations. Would it be a good use of JH's photographic papers to take a reverse of William Parsons' (3rd Earl of Rosse) drawings of nebulae? Cannot obtain Nicolas Clement-Desormes's or John Sharpe's papers. Doubts if the mode of measuring latent heat hitherto used can be recommended for accuracy.
[William] Penn produced letter written on WR's behalf by JH. Thanks JH for letter, which increased Mr. Slingsby's [?] confidence.
ES will write to M. F. Maury. Concurrence of both R.S.L. and B.A.A.S. is needed before congress is announced. Proofs of foreign responses to JH's circular will be ready next week.
George Bishop refuses permission for W. R. Dawes to edit Dawes's own observations. Portrait of Francis Baily should be nearly finished. Auction of Baily's books. Plans to start over 'de novo' and not use Baily's method for evaluating standards of measure. Convinced that standards must be connected with Ordnance survey of U.K. and T. F. Colby's units.
Response to questions on magnetic circular sent out by JH [see JH's 1844-12-5].
Evaluates in a detailed manner the magnetical and the meteorological observations organized by the British at various overseas locations. Makes many specific recommendations, generally supporting their continuation.
Hopes to inscribe a copy of Francis Baily's autograph on the proofs of his portraits. On the plates his full titles should be inscribed; asks JH's help in determining these. How RS can combine this with the autograph. On JH's dispute with James South.
Passes on information received from Thomas Maclear regarding stars. Has tried to use William Simm's object-glass.
Sends correction to data for Gamma Virginis. Asks if JH has 'considered the puzzle of Aristarchus [lunar crater]' discussed in WS's Cycle of Celestial Objects.
R.A.S. making exception in letting J. H. Mädler's chart be removed for JH. Continues observation of Gamma Virginis.
Giving the plan of the Observatory.
Describes testing William Simms's object glass and then gives details of the equatorial mounting GA used; offers to send carpenter to JH to construct mounting so JH can test object glass [diagram].
Note sent with package from [J. F.] Encke of Berlin.
Sends Gamma Virginis data. Will report Aurora Borealis observations to R.A.S.
Announces change in meeting time of Council on 14 May.
Announces 15 May meeting of Physics Committee.
Several items of R.S.L. business.
Hears from the Dean of Ely that JH is busy writing his B.A.A.S. oration. Sent a new volume yesterday. Wished JH had been at RM's soiree on Wednesday.
