Forwards reply from C. R. Weld explaining why Greenwich magnetic and meteorological observations were not sent to English and foreign scientists involved in global survey.
Has received the books. Began with Karl Holtzmann's and finds the reasoning at fault. Comments on this. [Marked 'not sent.']

Elizabeth Baily would like him to write an inscription for her brother's memorial tablet. Francis Baily was buried in the land of his fathers at Thatcham.

Further regarding the various theories on the latent heat of steam. Agrees with JH regarding the magnetic observations. Hudson's Bay Company has sent a large bill for J. H. Lefroy's expenses, which the R.S.L. declines to pay. Fears that Edward Sabine is out of humor about something.
Will help with the dispute between [W. R.] Dawes and [George] Bishop, provided certain things are understood by all the parties involved; enumerates these. Will speak as discretely as he can with [W. S.] Stratford.
JDH gives his opinion of the botanic garden in Brussels; he was impressed by the palm collection incl. Elate sylvestris & Caryota urens. The garden secretary Mr Drapier is unpopular. Mentions some other botanists of Brussels: Lucien; Dumortier; Galiotti, whose nursery he visited; Quetelet, who he met at the Brussels Academy. JDH admired the picture gallery in Brussels, especially the Rubens, & the Church of St Gudula. In Ghent he saw further fine paintings & churches. He also wen to Van Houtens nursery with [Joseph] Decaisne's brother, a regimental surgeon. Van Houten has impressive collections of camellias & palms. His collectors in Guiana, Brazil & West Africa were not productive. He is willing to exchange plants with William Jackson Hooker, for things from Antipodes & Jamaica plants such as [Ronald Campbell] Gunn's seeds. All 3 Decaisne brothers, botanist, painter & surgeon, have received the Legion of Honour. At Antwerp saw the cathedral, exposition of plants & botanic garden. Went on to Breda on the 'Diligence' then to Rotterdam & Leiden. At Leiden he has met with [Caspar Georg Carl] Reinwardt & seen the botanic garden, with excellent succulents & Japan duplicates to be sent to RBG Kew. JDH recommends further plant exchanges with the Dutch botanists as they have good connections with the Japan & Java. [Carl Ludwig von] Blume has shown JDH [the Rijkshrbarium] collection of Japan things; which he has at the expense of Siebold & is willing to share with JDH, incl specimen of Staffleria patina. JDH may extend his trip to see HORTUS CLIFFORTIANUS in Harlem & Linnaeus' Lapland dress in Amsterdam. JDH notes how spectacular Blume's collection of Orchideae, drawings & birds is. Visiting Leiden & the Jardin de Plantes, Paris have been epochs in JDH's life. Mentions the high opinion of WJH & his publications in Europe. Discusses his plans for taking over Robert Graham's lectures [at Edinburgh]. Muscologists in Leiden want [George] Gardner's Brazilian mosses.
JH's influence worked; J. W. Lubbock asked ES for list of recipients for Greenwich magnetic and meteorological observations. Preparations for new Arctic expedition. Will give copies of JH's letter to F. M. E. Wilmot and J. H. Kay. New observatory at Colombo [Ceylon]. Problem defining seasons for observations at St. Helena. Reply from W. E. Weber [to JH's circular].
Has written down what he gathered from HF on Tibetan dogs. Would welcome a few more details at any time, as he knows of nothing parallel to it.
Responds to questions on magnetic circular sent out by JH [see JH's 1844-12-5]. Comments on continuing government funding for global system of magnetic and meteorological observatories. Suggests goals for future observers.

Discusses cleavage planes of mineralogical specimens.
JDH informs his father, Sir William Jackson Hooker, that he has been looking through specimens at the Leyden [Leiden] herbarium with Carl Ludwig Blume. He is impressed by the number of things from Borneo, Java, Sumatra & Japan & wishes Blume would share duplicate specimens more readily. He suggests that they might exchange specimens if more willingly if places ever actually sent them things for their museum. JDH particularly notes how impressive Korthal's Nepenthes are. Blume & Sibeold have established a garden for things from Japan & Dutch colonies. Blume has promised JDH a specimen of a Sumatran Rafflesia & his described ferns & mosses. JDH describes his impressions of Blume & his wife. Explains that the Leiden herbarium did give India & Madagascar specimens to [Joseph] Decaisne in Paris in return for him doing dissections for RUMPHIA. JDH is disappointed that Blume has published nothing since BIJDRAGEN TOT DE FLORA VAN NEDERLANDSCH INDIË. Siebold only looks after the living plants. Miguel is developing connections with Japan & may in time be able to send specimens to RBG Kew but it will be a long time before his collections match those at Leiden. JDH suggests they send Blume named Java things to try & get Japanese specimens in return. There are two moss men at the Leiden herbarium: Dr Dozy & Dr Molkenboer who send duplicate material to Paris, the latter apparently wrote to WJH but got no reply. JDH thinks Miguel is a very promising botanist & RBG Kew should buy his work on Cycadeae. Miguel is working on peppers, figs & Suriname & Java plants. Many people ask JDH about Charles Darwin because of his book [about the voyage of HMS Beagle]. They also ask after [Robert] Brown. JDH informs WJH of his plans to travel to England from Brill or Hellevoetsluis via Rotterdam. He mentions the British Flora for Edinburgh students, he is glad in Scotland he will not have to lecture in Latin as they do in Leiden. He discusses the merits of Heward's plan for a plant & book agency.
Thanks WP for sending drawings and descriptions of various nebulae observed with WP's giant reflecting telescope. Comments on various nebulae. Expresses the idea that some planetary nebulae are 'hollow elliptical or spherical shells with or without a central Star.'
Actinometers are 'counterordered.' Reply from H. W. Dove to JH's circular. Problem defining seasons for tropical stations. Concerned that some authorities are reaching decision to extend or to terminate magnetic observations before receiving and reading Toronto volume. Failure of R.S.L. to send Greenwich magnetic and meteorological observations to appropriate recipients. Details of J. H. Lefroy's magnetic survey for Hudson's Bay Company, and misunderstanding over who would pay for Lefroy's transportation. Efforts by F. M. E. Wilmot to obtain ship for survey of [Cape of Good Hope]. ES concurs with Treasury's suggestion that copy of Toronto volume be sent to each colony. Observations of nebulae by T. R. Robinson.
