Thanks JSBS for his work. CD concludes the ferment of Drosera must differ from pepsin.

CD has forwarded proofs of Descent [2d edition]. Urges GHD not to work on them if his poor health makes them too tiring.

Thanks GHD about Spalding [i.e., for responding to Spalding’s request, see 9472].

Intends to keep working on [Descent, 2d ed.] proofs despite his illness.

Thanks GdeS for his "Études sur la végétation" [Ann. Sci. Nat. (Bot.) 5th ser. 15 (1872): 277–315]. "Nothing can be more important … than your evidence of the extremely slow and gradual manner in which specific forms change."

Hopes GdeS will shed light on whether polymorphic forms like Rubus and Hieracium are generating new species at present; CD doubts this.

Comments on CL’s planned bequest to science. CD would do the same if he had fewer sons.

Movement in plants; effect of syringing on Opuntia plants that capture insects with their flowers.

No summary available.

Will look for letters from JH in RG's father's papers.

JDH reports that the slightly cold weather in Cannes & Montpellier have aggravated his rheumatism. Criticises the maintenance of [Jules Emille] Planchon's garden in Montpellier & attributes this to the fact that they try to grow twice as many species as necessary on a small budget. The aging Professor Charles Martins gave a charming tour of the garden. At Montpellier station met with [Hugh Algernon] Weddell arriving from Cette [Sète], where he had been doing lichen research. Mrs [Frances] Hooker is going to Florence to stay with Miss Galton. JDH is happy 'to miss' the presidency of 'Section D' [at the Florence International Botanical Congress] & supports [John] Tyndall for a vice-presidency. Mentions the Roman ruins at Nimes & a trip from Nimes to Pont du Gard ruin, where he gather 42 species in a single spot. Tomorrow they leave for Antibes where they may see [George James] Allman if he has not left for San Remo. They then go to stay with Mr Hanbury at Mentone [Giardini Botanici Hanbury previously known as Palazzo Orengo], and on to Genoa, Pisa & Florence. JDH reports that [Geroge] Bentham is well but 'put out' to hear that Cambridge Universoty has awarded him the peculiar honour of LL.D. Adds that having met St George Jackson Mivart in Paris & found him to be a willing candidate for secretary of the Linnean Society this information has been met with enthusiasm from Frederick Currie [Currey].

[Letter in French, transcript available in French and English]. JDH writes to Sir William Thiselton-Dyer in order to practice the French he is learning. He writes that he & his party have travelled from Nimes to Arles, where he saw the Roman ruins, & from Arles to Cannes during which journey he admired the countryside & particularly the Pinus pinea groups by the sea. He compares Cannes itself to Torquay but less green. They then stayed with Mr Altmann at the Hotel du Cap in Antibes where they also met with Mr Thuret & Dr Bornet. JDH describes & praises Thuret's garden, which is full of plants from all over the world which thrive despite the extreme seasonal temperatures caused by the Mistral winds. JDH personally prefers the climate & greener vegetation of Madeira & Portugal to that in France. The cold weather in Antibes aggravated JDH's rheumatism, the season there is nearly over. He also met a Colonel Roper in Antibes who was there with his wife for her health. Colonel Roper was very well read in natural history, his wife went every night with a princess to a casino in Monaco at returned by train at midnight. JDH discusses Bornet's work on seaweeds which grow within the tissues of lichen & gives his own opinions, particularly on the 'gonidie'. He also mentions the possibility of lichens & algae with parasitic relationships, or whether it is more a case of their primordial condition. JDH continues the letter in English under the address Pegli, near Genoa. He writes that they will go next to Sestri, Spezzia & Florence & notes that [George] Bentham has had diarrhoea & JDH's own cough lingers.

JDH expects Smith has already told Thiselton-Dyer of his 'insouciance' respecting Nice. Thanks Thiselton-Dyer for correcting his [Kew Annual?] Report, he suspects the mistakes were in the record of garden arrivals as [Daniel] Oliver prepares the herbarium records & [John Reader] Jackson the museum acquisitions. He will consider Thiselton-Dyer's suggestion that [George] Nicholson prepare the garden records, as he considers him very able & thinks Smith should make more use of his talents. Mentions that Decaisne gave him Brouquarts'[?] Setewale [Curcuma zedoaria] of Carruthers. JDH will not reply to Miss Booth's letter yet as he wants to avoid visiting her in Lyons, they are trying to keep her father's botanical books together. Tells Thiselton-Dyer not to spend too long on JDH's [Royal Society Presidential?] address. Proposes that the paper on Nepenthes be a joint effort. Agrees with Thiselton-Dyer view on physiological research. Is anxious to read Sachs[?]. JDH calls Florence 'glorious'. The Horticultural Show & Botanical Congress are 'fiascos'. Filippo Parlatore is ill with whopping cough so JDH was made chair of the first session in his place, it should have been George Bentham. Lists some of the attendants. Mentions Carnel brought his Cynomoria to the congress & [Andrei Sergeyevich] Famintsyn read a paper on Myxogasters. Next JDH, Mrs [Frances] Hooker & Huxley go to Venice, then home via Munich. Allman is in Florence but will return in time for the first meeting of the Linnean Society in June.

JDH thanks Sir William Turner Thiselton-Dyer [WTTD] for his letter with news of the loss of the ship 'Liberia', on which their friends the Lowes were passengers. Richard Thomas Lowe's death means the Flora of Madeira will never be finished, like so many other systematic works of botany. In Filippo Parlatore's absence from the Botanical Congress, in Florence, JDH was elected to act as President. He describes how he went about organising & chairing the proceedings of the Congress. He mentions the following papers that were given: one on the Colchicaceae of Greece, [Andrei Sergeyevich] Famintsyn[?] on Myxogasters, Caruel on Cynomorium from Sardinia, Schimper on Astrophyllites from the gneiss quarries of Mont Blanc. JDH had to comment on the papers in his poor French which annoyed some attendees. A bust of [Philip Barker] Webb was invested. JDH & the Vice Presidents had an audience with the King of Italy [Victor Emmanuel II], who JDH calls 'repulsive'. JDH is now in Venice & will return home via Paris. [John] Ball & [George] Allman stayed on in Florence, but the latter must return home soon for his election to the Presidency of the Linnean Society. JDH informs WTTD that he is happy to be a President of the British Association [for the Advancement of Science] meeting but will be satisfied if he only presents the joint paper on Nepenthes. JDH & party are well, except for [George] Bentham who has had diarrhoea. JDH briefly had a cough but has recovered. Mr Harvey is also in Venice.
