Hoping to publish a register of examples of curves based on his own Septenary system of generating lines. Would JH be interested?

JM is traveling in Germany for some time and intends to end up at a scientific conference in Bremen. He encourages JH to try to attend that conference so they may become acquainted.

Birth of JH's daughter [Mathilda Rose]. JH's 'little travelers' will arrive soon to visit Baldwins at Anstey.

'Penny Post' is deluging JH with nuisance mail. Reviews JH's efforts to obtain object glass for equatorial telescope at Cape of Good Hope. Trying to convince G. B. Airy to purchase from Merz and Mahler in Munich, rather than from William Simms. Russia is using TM's 'Cape Arc' in survey of its entire country.

Agrees to host congress at Cambridge to assess data from [magnetic and meteorological] observations. Suggests adding D. F. J. Arago to list. Will include this in GP's address to B.A.A.S at York. [JH annotation: List of five members.]

A. T. Kupffer proposes international meeting of authorities in terrestrial magnetism. ES suggests combining this with 1845 meeting of B.A.A.S. at Cambridge. Plans for publishing observations before Cambridge meeting.

Ship is ordered for Lt. Clark's excursion. Feels certain that Lord Stanley has consulted colonial governor.

JH is premature in concluding that international meeting of magnetic researchers would result in appeal to British government for funds to continue B.A.A.S. observatories beyond 1845. ES has not reviewed later observations [1842-43] and cannot judge whether observations have met original goals of R.S.L. and B.A.A.S. Agreement by Robert Peel and F. I. Brunnov on need for longer period of observations. Affirms value of JH's role in evaluating results of survey.

ES agreed to superintend publication of magnetic observations only because Humphrey Lloyd refused to do so any further. Format intended for each volume. Gratitude for JH's contributions to magnetic research. [P.S.: Provision of instruments to U.S. observers.]

Does not believe that a magnetic congress held at this time would be productive or representative; a better job could be done by letter.

Will be in London and hopes to see JH. Thanks for his letter and the promise of sending his papers on light. Also wants information on [Louis] Daguerre's work.

Announces the discovery of a new comet by [Heinrich] D'Arrest, a university student. Wilhelm Struve has seen it.

Reports the birth of JH's 9th child, Mathilda Rose Herschel.

Tries to obtain equatorial telescope for Cape Observatory. Works only on Cape Results and his children's education. Mentions reforms in southern constellations. Announces birth of seventh daughter [Mathilda Rose].

When his packet is ready for the Cape, forward it to him at the Admiralty and he will arrange for it to be sent. Congratulations on the new addition to the family. When next in town perhaps he would be interested in seeing the new object glass for the Cape, which William Simms is preparing.

Will send his letter to Thomas Maclear with one of his own. Agrees with him regarding the object glass, but feels that English artists should be encouraged.

Has traced the comet notified in J. F. Encke's circular. Gives his readings for its position. Has compared the stars near it. Hopes JH's family are all well.

Now a long time since she has written but she has happy memories of their last meeting. Is anxious about the posthumous fame of her son. Would be pleased to hear news of the family.

Talks about stiffening a vertical circle, or tube; explains that southern constellation remodelling has been very minimal.

Seeks WW's advice on a proposal that an international magnetic congress be held in conjunction with the 1845 B.A.A.S. meeting in Cambridge.
