JH comments on JL's 'memoir on the heat of vapours,' indicating JH's dissatisfaction with the experimental basis (the experimental work of J. L. Gay-Lussac) for the conclusions. JH offers improvements in the construction and operation of the ice calorimeter.
JH has arranged for U. J. J. Leverrier, J. C. Adams, and Wilhelm Struve to visit JH together at Collingwood. JH is writing to invite JL to join them.
As JH's [1854-4-28 ?] did not elicit a response, JH is again trying to arrange at what station to meet JL.
Promises to become more knowledgeable about [heat?] theory in order to be able to discuss it with JL. Cautions that the subject is an intricate one.
Mostly news of JH's family; JH inquires as to the state of health of JL's mother.
JH is trying to arrange where to meet JL.
JH expresses some concern about the accuracy of a wet bulb thermometer, as he is not clear about the nature of the experimental base for its use.
Thanks for 'small, but intense' volume sent.
Is displeased by R.S.L. Council's seemingly rash resolution with regard to idea of permanent magnetic observatory.
Thanks for letting JH know about honor accorded at 'the Anniversary' [Meeting]. Offers condolences on JL's 'late severe loss.'
Advice as to best way to present JL's method of calculating the orbits of comets to R.A.S. If JL desires R.A.S. to undertake calculations, might be some difficulty.
In light of minutes of R.S.L. Council meeting, outlines vision of permanent national physical observatory and, more importantly, an experimental institute or college. Hopes Edward Sabine will be interested.
About observing binary stars. JH has decided not to accept the offer of passage on a war ship to the Cape of Good Hope, as he wishes to be beholden to no one for the results of the expedition.
Comments on several different reports; also on some experiments that lead JH to think much of the radiant energy of the Sun is absorbed in the atmosphere.
On the 'misfortunes & mishaps' of the Aden magnetic observatory and on the proper care of magnetical instruments.
Hopes JL will call application of JH's brother-in-law for position of Secretary of Bank of Asia to attention of a director, who is JL's relative.
Thanks for work on lunar theory. Sends news from Feldhausen, noting 'latest Astronomical novelty,' the sudden growth of star Eta Argus.
Asks whether JL wishes to present method [see JH's 1847-12-4] at next R.A.S. meeting.
Cannot accept JL's kind invitation. Predicts a storm regarding the jury awards for the Great Exhibition.
