Delighted that Brongniart thinks Sigillaria aquatic, and that E. W. Binney thinks coal is a sort of submarine peat. Thinks coal-plants will prove to be aquatic, though JDH will sneer at this.
Has acquired a new microscope.

Arranges concurrent meetings of Standards Committee and Visitation [to Greenwich observatory]. Possible explanation for notations in [Thomas Henderson's] 'tables at June 11.' Please review and edit 'Preface to Lalande.' Will write to [Elizabeth] Baily.
Comments on the paper he has sent him. Finds it difficult to give an opinion as so much verification is required.
[Extract of letter to WJH from T. E. Cantor] on zoological distribution in the Malay Peninsula.
Asks if the recent discussion of what name, 'Leverrier' or 'Neptune,' should be used for the new planet changed JH's opinion on whether the name used in the Nautical Almanac for JH's father's planet should be 'Georgian Planet' or 'Uranus.'
Is searching for a Robert Georg Twaddel; asks JH whether he knows anything of him.
Approves naming the new planet Neptune and continued designation of JH's father's planet as Uranus. Suggests reasons and alternatives.
About the lunar model made by WW, and being considered for purchase [see JH's 1846-2-20].
Sends parcel of specimens for R. W. Bunsen.
Encloses letter from W. S. Stratford at R.A.S. How RS plans to distribute works on J. J. L. Lalande and N. L. Lacaille left unfinished at death of Francis Baily.
Speculates on name for JR's 'hot and cold basins' and on causes of equatorial heat and polar cold.
Looking forward to learning JH's opinion of Richard Sheepshanks.
CD defends his position on submarine coal formation and coal-plants against JDH’s strong objections.
Has the papers by [Thomas] Henderson but they do not contain much information.
On a puzzling aspect of [Thomas] Henderson's papers. One column in his tables seems to have been altered in someone else's handwriting. Wants to know the origin of these corrections, and how Henderson's tables ought to be printed. Offers several options.
Professor [H. J.] Anderson of New York wishes to be introduced to JH. Number 600 of Astronomische Nachrichten will finish the 25th volume of the journal. Wilhelm Struve will be present.
Cannot explain how Thomas Henderson arrived at special figures in N. L. Lacaille's star catalog. Will examine Lacaille's volumes tomorrow.
Arranges a meeting the next morning with JH.
Discusses the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
Replies to some of the queries from JH's 1847-5-6 letter.
