Further about the map printing problem [see FB's 1841-4-6].
Is delighted at the prospect of JH's article being included in the next number of the Quarterly Review. Is not surprised it will extend to fifty pages, but hopes he will remember the 'general reader.'
Measuring work of the base line is virtually completed and levelling of the line will commence forthwith. Has devoted every day to the work except Sundays. Comments on various aspects of the work. F. E. Wilmot wishes he had not returned the rusty dip bar. Obelisk is on board the Romeo.
Reports receipt of a communication, which argues that all elements are merely isomers of one substance. Expresses support for such a view.
M. F. B. Dausse visited FW several times to study instruments and copy meteorological observations. Dausse urged FW to share these with D. F. J. Arago, who is concerned at delay in publishing survey results. Please notify R.S.L. that Arago's official request will arrive soon. Encloses copy of FW's 15 Apr. 1841 letter to Arago. New rain gauge. Problems with anemometer and dipping needle. Will visit Cape Agulhas with Thomas Maclear to make magnetic observations.
List of papers JH took from CLH on his 'last visit' to [Hanover]. Miscellaneous notes about relatives and acquaintances.
Forwards request of the Secretary of the Treasury for justification of public monies for expenses incurred for magnetic and meteorological observations of the Antarctic expedition. Brief note from JH should suffice for House approval. Note should mention G. B. Airy's request concerning the reduction of the Greenwich lunar and planetary observations and Francis Beaufort's concerning navigation. ES promoted to Lieutenant Colonel.
Provides examples to justify governmental support of various magnetic and meteorological observations. States that 'Terrestrial magnetism ... of all sciences of observation holds out the greatest present prospect of decisive reduction under ... exact theory.' Mentions work by N. L. Lacaille and Thomas Maclear at the Cape.
Quotes passage from C. E. Trevelyan (Treasury Office) to [Hussey] Vivian concerning the number of copies of published data and the number of magnetic observatories. Requests JH's perusal and advice. Includes letter from [A. T.] Kupffer on latest observations.
Has not unpacked William Herschel's letters that JH secured from the R.S.L.
Sends letter on the subject of the star maps.
Regarding the payment of John Arrowsmith's bill for the printing of the star maps, which seems excessive in relation to the low standard achieved. Would like FB's comments.
Has communicated JH's remarks to John Arrowsmith. Is sorry for the inconvenience caused.
Would like some dry prints of the star map, if no further expense is involved. Is sorry that he has caused him all the bother.
John Arrowsmith has undertaken to make further copies of the star maps on dry paper, free of charge.
Sends missing barometer observations from Montreal, Flushing, and Albany. B.A.A.S meeting postponed.
Doubts that isomerism of all elements can be verified experimentally, but notes a number of groups with similar atomic weights that might well fit. Further on vegetable colors in photography. Refers to enclosure of a further dialogue on infinity.
