JDH writes that he is sending Sir William Turner Thiselton-Dyer [WTTD] the list of herbarium visitors for the RBG Kew annual report, he was not sure whether to include [George] Bentham's name. He notes that the list shows a 'wonderful amount of botanical query & activity'. JDH is now preparing the list of additions to the herbarium, including the extensive list of [Georg Wilhelm Heinrich] Schimper & General William Munro's donated herbaria. JDH discusses the benefits of WTTD going to Court, both for him personally & for the office of Assistant Director of RBG Kew. JDH mentions that he likes the hotel Romain, where he is staying in Paris. He & his party plan to dine at Lavalier's & Capones[?] in Paris before travelling south.

JDH is sending Sir William Turner Thiselton-Dyer [WTTD] the prepared list of donations to the RBG Kew herbarium, for the annual Kew Report, which will need revising by WTTD & [Daniel] Oliver. They may also wish to edit Hooker's eulogy to [General William] Munro. JDH cannot work up the list of Kew's publications without references so the Report will be delayed beyond the end of Mar this year. JDH & [Asa] Gray have visited [Joseph] Decaisne who is convinced that a student of his can define the characters of the natural orders based on hairs[?], & Decaisne is classifying species of Clematis according to the bristles on the stem & testa, which Baillon[?] will undoubtedly debunk. They visited the Jardin des plantes where JDH observed about 18 immature species of Madagascar palms. Also met: [Marie Maxim] Cornu, [Philippe Édouard Léon] van Tieghem, [Pierre Étienne Simon] Duchartre & [Gaspard Adolphe] Chatin. They have dined at Lavalier's & been to St Denis. Next they go to Chambery, Turin, Genoa, Pise [Pisa], Rome & Naples.

JDH reports that he has arrived in Rome. En route the party stopped in Paris & dined with Lavalie[?] & Copen[?], the latter may leave his herbarium to RBG Kew. They then travelled through Chambery & Turin, where they saw the Champollion Collection of Egyptian Antiquities but JDH forgot to call on Giovanni Arcangeli who is a professor there. JDH admired the view of the Alps towards Monte Viso from an 'Alpine club' house at Turin. After Turin they went to Genoa & tried unsuccessfully to call on the Marquis Giacomo Doria. They also saw the Doria Natural History Museum with a splendid collection of animals from the Malay Islands & called on Federico Delpino. JDH revisited the palaces with the Van Dyke paintings he saw in 1874. He calls the Genoa botanic garden 'small & miserable'. From Genoa they took the train to Pisa where they met up with Betsy White as was. JDH describes the Duomo they visited in Pisa. He also describes the scenery en route from Pisa to Rome. They will next go to Castellammare & stay at the Hotel Quisisana in Naples before returning to Rome. They have briefly seen Miss May Symonds & her brother. JDH notes how sparsely populated, though cultivated, the plains of Italy are. He has seen a few wild flowers: anemones & violets. Curiously the bark of almost all the trees south of the Alps is very white: Planes, Poplars, Mulberries & Elms.

JDH writes to Sir William Turner Thiselton-Dyer from Castellammare, where he & Lady Hooker have just arrived after spending some time in Rome & Naples. At Naples he visited [Anton] Dohrn's aquarium. He describes some animals of particular interest he saw there: Crinoids, Sepia [cuttlefish], Octopus & Loligo [squid]. He also mentions seeing fish, Ascidia, Corals, Madrepores, Melobesias, Diptera, Beroe, Crustacea, Meduseus & Ulva. In the Naples museum JDH admired the statuary especially a head of Homer & a Venus after Milo. He found the collection of paintings inferior to those at the Vatican & preferred the murals & artefacts from Pompeii, especially: a pane of glass, a surgeon's instrument, a glass plate & a blue glass flagon. JDH has visited Pompeii & tried to understand exactly how it was preserved by the volcanic eruption, he is puzzled why there are not more charcoal remains of the wooden upper stories of buildings & speculates that the town was only partially buried & the exposed material later carried away. Castellammare is where Pliny the elder died during the eruption. JDH is keen to see Herculaneum & understand how its artefacts were not all destroyed by the lava. He also wanted to see Professor Luigi Palmieri at the observatory on Vesuvius but Palmieri is in Rome. JDH intends to ascend Vesuvius the next day. JDH visited the Naples botanical garden but did not see Vincenzo de Cesati or Giuseppe Antonio Pasquale. JDH calls the garden 'wretched' but he did learn something there about Mediterranean Pini. JDH will next go to Amalfi, Salerno & Paestum but not to Capri or Monte St Angelo because of the poor weather. Odoardo Beccari was in Rome appealing against the removal of a herbarium in Florence. JDH comments on the news of Mrs Meade's death & on the poor botanical knowledge of Sir John Lubbock. JDH has asked [John] Smith to give Dyer a list of all RBG Kew garden staff. JDH comments briefly on vegetation in the area, including sour oranges.

JDH informs Sir William Turner Thiselton-Dyer that he has asked [John] Smith to send William Govett Romaine some green house things, Romaine was helpful to RBG Kew as Secretary of the Admiralty. JDH mentions some correspondence with Sir Charles Wyville Thomson. Since last writing JDH & his wife [Hyacinth Hooker] have been to Amalfi, Sorrento, Paestum & up Vesuvius & have visited Anton Dohrn's aquarium & museum in Naples. Next they will go to Rome & Florence. JDH has also written to Reverend William Samuel Symonds & his son 'Willy' [William Henslow Hooker]. Letters can be addressed to JDH as follows: Maquai, Hooker &c Care of Bankers.
