Last letter to JH was private [see GA's 1845-4-1].
Gives detailed, official, replies to the questions in the magnetic committee circular [see JH's 1844-12-5].
Illegible.
Has been appointed keeper of Mining records at the Museum of Economic Geology. Hopes to meet him personally and thank him for his assistance.
The President was requested to write to the East India Company about the observatories. Continuance of the magnetic observations at Greenwich was referred to the Committee of Physics. Cannot find where Nicolas Clement-Desormes's observations are published. Has been studying the wet bulb problem. Capt. Herbert has denounced the article on hygrometry in Brewster's Encyclopaedia.
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.
Asks JH's opinion on a paper on magnetism by Karl Reichenbach, which has some 'very extraordinary' statements.
Will direct JH's 14 Apr. letter to Prince Metternich.
As trustee of marriage settlement of CB's sister [Mary Anne Hollier], JH is asked to sign enclosed order. Reports distribution of money to sister and to H. J. Hollier.
Received JH's directive to send dividend to Mary Ann Hollier. Other money is invested in property at Cardiff, owned by Mr. Hollier. CB in bad health. Questions authorship of Vestiges [of Creation].
Sends specimen of esculine, or polychrome, extracted from horse chestnut. It exhibits optical properties that JH recently investigated. Offers to send specimen of colophene. Asks JH's recommendations for foreign secretary of R.S.L., following death of J. F. Daniell. This officer must supervise magnetic and meteorological observatories. [JH annotation: 'By all means appoint Sab(ine).']
Will invite G. A. Erman to act as B.A.A.S. commissioner in reduction of 1829 Gaussian constant. Will try to remedy misconceptions of G. B. Airy. T. M. Brisbane will not get involved. Testing new magnetic instrument by Humphrey Lloyd for Arctic expedition. Invite C. F. Gauss to Cambridge.
Reply from G. A. Erman to JH's circular is best one yet received. Erman recommends calculating magnetic constants of 1829. ES suggests grant from B.A.A.S. to fund this. Alexander Humboldt will reply soon. Charles Wheatstone should describe new apparatus in letter to JH that can be sent to observatories.
Received reply from Karl Kreil in letter from Count Senftenberg, who owns private magnetic and meteorological observatory east of Prague run by Kreil's former assistant. ES asks JH to write letter to Clemens von Metternich, as requested by Senftenberg. High regard for Kreil's work.
Received thirteen replies to JH's circular; nine remain unanswered. Suggests printing these, before they are published by B.A.A.S, and distributing these along with second circular by JH.
H. U. Addington will send JH's letter to Clemens von Metternich via Robert Gordon, English minister to Vienna. JH may include George Peacock's signature also. Printer will send proofs of replies to JH's circular to JH for corrections. JH's estimate for expenses for observatories is too high. Sent copy of JH's circular to Charles Wheatstone.
Published opinions on magnetic and meteorological survey should be restricted to correspondents who were directly involved in observations, particularly foreign participants. Most others may express their views at B.A.A.S. meeting in Cambridge. Recommends omitting M. F. Maury's letter and including that of J. M. Gilliss.
Response to questions on magnetic circular sent out by JH [see JH's 1844-12-5].
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.
