About the lunar model made by WW, and being considered for purchase [see JH's 1846-2-20].
Encloses letter from W. S. Stratford at R.A.S. How RS plans to distribute works on J. J. L. Lalande and N. L. Lacaille left unfinished at death of Francis Baily.
Looking forward to learning JH's opinion of Richard Sheepshanks.
Professor [H. J.] Anderson of New York wishes to be introduced to JH. Number 600 of Astronomische Nachrichten will finish the 25th volume of the journal. Wilhelm Struve will be present.
Cannot explain how Thomas Henderson arrived at special figures in N. L. Lacaille's star catalog. Will examine Lacaille's volumes tomorrow.
Arranges a meeting the next morning with JH.
Discusses the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
Replies to some of the queries from JH's 1847-5-6 letter.
Can offer no explanation of how Thomas Henderson computed tables from data in N. L. Lacaille's star charts. Henderson did all his work at home. Suggests explanations for Henderson's corrections in red ink.
Reports that the RAS has an available balance of £77. He calculates that to complete the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française... and N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere, however, will require £83 pounds; WS hopes to cut costs so that they do not overspend their grant.
Concerning Thomas Henderson's reductions of N. L. Lacaille's observations.
Sending to JH some information about 'L's catalogue' [either N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere or J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....]
Although WS is suffering from gout, he promises to work on the layout of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
Congratulates JH on finding solution [to Thomas Henderson's notations]. Sends extract of 11 Mar. 1841 letter from Henderson, stating that Henderson used computations in Francis Baily's edition of N. L. Lacaille's catalog. RS's notes on observation and reductions of J. J. L. Lalande. Sent skeleton of RS's 'Preface' to W. S. Stratford.
Discusses the layout of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
About a time conflict involving the R.S.L. and Visitation Day at the Royal Observatory.
Asks JH for measures of several double stars.
A note enclosed with the printed observations made with the Northumberland equatorial telescope.
Has directed the printers, Taylors, to send JH's booksellers the parts of the Barometrographia as issued, free of all costs. The science of meteorology attracts little attention at the moment.
Believes that RS's suggested correction, 'when translated into its equivalent value in terms of the inclination,' will provide sought-for values.
