Rejoices that JH plans to persuade H.E.I.C. to publish results of magnetic and meteorological observations. No one at R.S.L. has been in charge of these observations since Humphrey Lloyd gave it up. Submits JD's list of stations and observations. Encloses specimens of JD's pure 'anchovia' and 'Sabrina.'

Sends the amended books. Regarding payment by the week or day. Hopes that the dispute with Mr. Morrell can be amicably settled.

How to obtain copies of H.E.I.C. observations. Humphrey Lloyd never intended to process data from H.E.I.C. observatories; these were added to survey after Lloyd's original (1838) offer to superintend B.A.A.S. observations. Sends copy of Toronto volume to JH to use as model for H.E.I.C. publications. Asks for JH's suggestions for Arctic observations next winter. Encloses note from [T. R.] Robinson in Parsonstown.

Reviews establishment of H.E.I.C. observatories and comments on quality of magnetic and meteorological observations at Simla, Madras, and Singapore. Has heard nothing from A. B. Orlebar, director of Bombay observatory.

Activities at H.E.I.C. magnetic and meteorological observatories in Simla, Madras, and Singapore. Results from Simla, elevation 8000 feet, will complement high altitude observations in Europe. Vertical force instrument at Singapore is better than at all other stations, but high humidity there makes actinometer unreliable.

Is grateful for his letter regarding the Portland vase; has shown it to Peel, who has agreed to introduce a short bill to protect such properties. Will read JH's letter to the Trustees.

Much obliged for JH calling but regrets he was out. The question [on steam] they have been discussing seems to be answered by a paper by a Prof. Karl Holtzmann he has just come across; comments on this. If JH is coming to S. J. A. Compton's (2nd Marquis of Northampton) soiree will he come and dine at St. James' Place?

Thanks for JH's valuable information on actinometers. Encloses particulars that HB sent to [J. H.] Kay along with instruments.

Based on JH's 1821 formula in R.S.P.T., WN calculated aberrations of compound double achromatic object glasses, to be used in determining radii for grinding lenses. Explains theory. Attempting to construct 4.2-inch lens.

Was not aware when he wrote his paper that doubt existed regarding the invariability of [the absolute heat of steam?]. Comments on the variations in the theories of S. D. Poisson and Karl Holtzmann. The experiments JH suggests would be highly interesting. Would he like to see Holtzmann's paper?

Lists 17 foreign and six English scientists to whom ES sent JH's letter and Toronto volume.

Has no doubt that any improvements JH suggests should be published. [John?] Taylor has borrowed Holtzmann's pamphlet, which will be sent as soon as returned. Karl Holtzmann's formula for air appears quite out. Gabriel Lamé evades the question. If JH writes anything on his calorimeter hopes he will mention the various questions raised.

Judges the unfinished portrait of Francis Baily a faithful rendering, although he is portrayed without the glasses, which he usually wore. Fears the intractability of [W. S.] Stratford and its implications for the workings of the R.A.S. Council. On the dispute between [W. R.] Dawes and [George] Bishop and how to resolve it.

Reports in considerable detail on magnetical and meteorological observation in Russia. Supports the idea of international conference of leaders in such work.

[Detached postscript] Asks JH's opinion of new apparatus that [William] Simms will soon put on paper.

Forwards reply from C. R. Weld explaining why Greenwich magnetic and meteorological observations were not sent to English and foreign scientists involved in global survey.

Elizabeth Baily would like him to write an inscription for her brother's memorial tablet. Francis Baily was buried in the land of his fathers at Thatcham.

Further regarding the various theories on the latent heat of steam. Agrees with JH regarding the magnetic observations. Hudson's Bay Company has sent a large bill for J. H. Lefroy's expenses, which the R.S.L. declines to pay. Fears that Edward Sabine is out of humor about something.

JH's influence worked; J. W. Lubbock asked ES for list of recipients for Greenwich magnetic and meteorological observations. Preparations for new Arctic expedition. Will give copies of JH's letter to F. M. E. Wilmot and J. H. Kay. New observatory at Colombo [Ceylon]. Problem defining seasons for observations at St. Helena. Reply from W. E. Weber [to JH's circular].

Responds to questions on magnetic circular sent out by JH [see JH's 1844-12-5]. Comments on continuing government funding for global system of magnetic and meteorological observatories. Suggests goals for future observers.
