Can he recollect the origin of Table V in the Report of the Committee on Meteorology showing the elastic force of aqueous vapor? James Apjohn says JL calculated it but JL has no recollection. JL's mother is in a hopeless state.

The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Can he recollect the origin of Table V in the Report of the Committee on Meteorology showing the elastic force of aqueous vapor? James Apjohn says JL calculated it but JL has no recollection. JL's mother is in a hopeless state.
Many years ago JH questioned him about the calculation of the perturbations in an inclined orbit, the satellites of Herschel [Uranus] for example. Has only recently seen the light. Is now confident that he can calculate the perturbations of any planet in any orbit. Gives details and would be glad of JH's comments.
Has been induced to become a candidate to represent the University of Cambridge in Parliament and encloses his address. Would like JH's support.
A circular letter to the electors of the University of Cambridge, asking for their support in the upcoming poll for representative to Parliament [see JH's 1832-11-30].
Will JH be able to dine with the other visitors at Greenwich on Saturday? JH has been awarded a Royal Medal. Thinks JH is wrong in not desiring a passage to the Cape in a Man of War.
J. T. Boileau and L. E. O. Ludlow were appointed by H.E.I.C. to direct Indian observatories. R.S.L. is concerned that it has no choice in selecting directors. Instruments for H.E.I.C. observatories. Should JL request additional staff for all 16 observatories, or only for nine permanent ones?
Has he succeeded in obtaining a Daguerrotype for J. C. Ross? Thinks one or two would be desirable. Has got one himself and obtained good results. Two of his family are ill, which brings him to town. Hears that JH has got colors, which is a great step.
Has read over all JH's report. Makes suggestions for alterations and omissions to bring it into line with the wishes of Council.
Sends a copy of his work on the tides. S. D. Poisson's theory is noticed near the end of the 2nd volume of Mécanique. Thinks some experiments are necessary to find the effect of the sun on climate. Has received a note from the Treasury.
Would like JH to amalgamate William Whewell's and JL's memoirs. Thought the principle of universal gravitation was conceded by all. Treasury have sent back the bills and want the Antarctic ones separated from the Observatories ones. Should take notice of the effect of iron steams [on instruments?].
Sends a copy of the report, which he has looked over with P. M. Roget. S. H. Christie seems averse to altering it. Thinks it important to make observations of the temperature with barometric readings in balloon ascents. Only readings by J. L. Gay-Lussac at present.
Has received letter and report. Will he consider by Thursday whether to refer the report back to the Committee. Does not think the balloons should be too large. Regarding the sun's effect on climate. Presumes Council cannot alter report.
Regrets that JH in his address to the R.A.S. should have omitted to mention the names of P. G. le D. Pontecoulant and JL in connection with the calculation of the lunar and planetary perturbations.
Thanks for his letter. Will communicate to P. G. le D. Pontecoulant what JH has to say about him. It was certainly unwelcome that JH should omit JL's name when referring to the lunar theory.
Sent an extract of JH's letter to P. G. le D. Pontecoulant. Now gives an extract from Pontecoulant's reply. Is sorry they are not to see JH at S. J. A. Compton's (2nd Marquis of Northampton) tonight.
Has talked to William Lamb (Lord Melbourne) about permanent magnetic and meteorological observatory. Was received 'as well as we could have anticipated,' but without definite answer. Thinks head for observatory should be appointed and give lectures.
Council passed 'with great unanimity' resolutions regarding permanent magnetic observatory to be established in London.
Further remarks on council meeting about permanent magnetic observatory and G. B. Airy's answer [to invitation to head it?]. Awaits communication from William Lamb (Lord Melbourne).
Placed JH's letter before the Committee of Papers but the Committee did not change its views regarding the publication of W. H. F. Talbot's paper. Is pleased JH is promoting his experiments so successfully.
J. F. Daniell informs JL that the table was calculated by William Galbraith. James Apjohn states everyone is in agreement that the absolute heat of steam is constant, but JL disagrees. Intends raising the matter of John Southern's experiments at the next meeting of the B.A.A.S.
