[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.
