Is searching for a Robert Georg Twaddel; asks JH whether he knows anything of him.
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.
Thanks JH for birthday wishes for JH's aunt Caroline Herschel. Goes on to tell JH about Caroline's health, both physical and mental, and about the birthday celebration for Caroline.
Has just read W. R. Dawes's description of the observatory at Camden Lodge and the telescope by eorg Merz makes TM envious. Hopes JH will press claims for one for the Cape. Is at present engaged sinking the Sector for shelter. TM has suffered much from the effects of the heat. Dr. Gall has died, aged 98. What a drubbing G. B. Airy has given R. H. Inglis.
Cannot explain how Thomas Henderson arrived at special figures in N. L. Lacaille's star catalog. Will examine Lacaille's volumes tomorrow.
Arranges concurrent meetings of Standards Committee and Visitation [to Greenwich observatory]. Possible explanation for notations in [Thomas Henderson's] 'tables at June 11.' Please review and edit 'Preface to Lalande.' Will write to [Elizabeth] Baily.
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.
Believes that RS's suggested correction, 'when translated into its equivalent value in terms of the inclination,' will provide sought-for values.
Dispute with W. S. Stratford over proof sheets. Efforts to appease [T. R.] Robinson. RS's progress on works of N. L. Lacaille and J. J. L. Lalande.
RS will disclaim editorial responsibility for 'Preface' to J. J. L. Lalande's work if W. S. Stratford modifies it substantially. G. B. Airy is upset by omissions in 'Preface.' Usefulness of J. B. J. Delambre's work in understanding observations of N. L. Lacaille.
Aggravated by W. S. Stratford's refusal to send proofs [of 'Preface' to J. J. L. Lalande's work] to RS.
Repeats yesterday's protests against W. S. Stratford's refusal to send revised proofs to RS. Hopes G. B. Airy will not blame JH for delay.
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.
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.
A notice of meeting of the Standards Commission.
