Brief note alerting JH to the presence of a foreign visitor.

WP identifies date and people present at the time of the experiment referred to by JH in his 1845-11-9.

Is sending JH some powder that HP thinks might be a good compound for polishing telescope specula.

Invites JH to come to the magnetic conference meeting being held at the B.A.A.S. meeting.

Sends JH a copy of the resolution dealing with the publication of Fauna Antiqua Sivalensis.

Informs JH that the committee to deal with the publication of Fauna Antiqua Sivalensis has been struck and is to prepare a request to the government for aid in publishing.

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].

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

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.'

Accepts JH's invitation to join Magnetical and Meteorological Committee of B.A.A.S. Will see JH at Cambridge next week. T. M. Brisbane's magnetic observations will be published in Transactions [of Royal Society of Edinburgh]. JH was responsible for making these known.

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).']

Acknowledges receipt of JH's order from B.A.A.S. for £30. Mr. Harris is much worse and cannot respond personally.

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.

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.

Proposed date for B.A.A.S. meeting creates difficulty for HL. Assurance that no one other than JH could have provided such vital leadership for global magnetic survey. Doubts that [James] McCullagh could serve committee well; suggests [J. D.] Forbes instead.

Response to questions on magnetic circular sent out by JH [see JH's 1844-12-5].

Informs JH that 'It is necessary to ask you as President of the British Association to preside at the General Advisory' to be held on 16 June. JH should also inspect the Cambridge Observatory.

Arrangements made for copies of the B.A.A.S. Catalogue of Stars to be distributed to public institutions and to individuals.
