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.
