Proposed travel arrangements for JH.
Decides not to print G. Reichenbach's papers on JH's advice. Will consider Reichenbach's papers in the future.
Thanks FB for some papers; raises questions relating to remodelling the constellations of the southern sky.
Asks GA on behalf of F. W. Bessel, for unreduced positions of a star that FB wishes to examine for annual parallax.
The colored meteors were too low on the horizon for JH to see them. Comments on the number of falling stars when comets approach the earth. Sends copies of his essay on comets and a book for children. Is working on various papers including one on 'Deafness in Balloons.' Is co-operating with L. A. J. Quetelet in a Register of Periodical Phenomena.
Regarding H. C. Schumacher and the Stephen Groombridge observations.
Requests copy of JH's observations made in 1811. Asks latest opinion of JH on Gamma Virginis before the publication of his Cycle of Celestial Objects for the Use of Naval, Military, and Private Astronomers.
Is grateful for the very interesting photograph; will keep the preparation secret if he discovers it. Has been trying many experiments with benzoates with curious results, but bad weather has stopped progress so has now turned to thermography to test the truth of Mr. Prater's conclusions. Comments on these.
Invitation from the Local Council to visit Cork for the B.A.A.S. meeting.
President of the Società Italienne des Sciences has received the invitation for members to attend the B.A.A.S. meeting at Cork. Regrets the length of the journey prevents members attending, but have nominated Michael Faraday to attend.
Apologizes for confusion about F. W. Bessel's request [see GA's 1843-6-6], but JH had neglected to check date on FB's letter.
Will review all Gamma Virginis observations before revising orbit. Catalogue of major nebulae complete; will work on minor nebulae next.
Regarding a letter from F. W. Bessel. On holiday on the Isle of Wight.
Is on the point of returning to the Cape and will be pleased to deliver anything to Thomas Maclear. Has borrowed three chronometers from the Admiralty for the magnetic survey. His stay was too short for him to visit JH.
Completed 'one of the most curious products' of JH's Cape Results: the map and catalog of the 'Nubecula major' region.
Comments on book on etymology forwarded by Sherwood & Co. [see 1843-5-26].
Sends JH's 1817 observations; cannot locate any he made in 1811. Tells WS Gamma Virginis measurements will take more time.
Sending details of a singular appearance in the heavens on 16 June.
Answers questions raised in JH's 1843-6-5; comments on other astronomical matters.
Discusses deficiencies in astronomical equipment at Cape's observatory, and troubles in observing comets, double stars, and other phenomena. Hopes equipment can be updated.
