Thanks for letter relating to domesticated bullfinches’ instinctively cutting off cowslips [see 9430]. Suggests observing whether the birds swallow any part of flower or particular parts.

Thanks for recent edition of CD’s Journal of researches.

[Letter in French, transcript available in French and English]. JDH writes that he is sending Sir William Turner Thiselton-Dyer [WTTD] a corrected copy of the [KEW ANNUAL] REPORT & leaves it to WTTD's discretion when it is ready to send to the printers. JDH & his party travelled to Nimes by rail via the mountains from Clermont Ferrand & JDH was impressed by the basalt landscape, which he describes. The vegetation is not more advanced than in England but the trees coming into leaf were attractive. JDH wonders why there is so much variation in the colour of different species' young leaves but not their mature foliage. In the southern valleys JDH saw olive, wild chestnut & evergreen oak. JDH praises the Jardine de Plantes, Paris, which [Joseph] Decaisne showed them. JDH discusses [Adolphe] Brogniart's views on palaeobotany; his opinion that [William] Williamson's theories are superior to [William] Caruthers' & his belief that there are no Polypodiaceae fossils in the coal beds. The party will next visit [Jules Emile] Planchon in Montpellier then go to Pont du Gard, Arles, Cannes, to see Mr [Gustave-Adolph] Thuret in Antibes & [Daniel] Hanbury in Menton. There is an addenda to the letter, written in English, under date 30 [Apr 1874] in which JDH reiterates the places they have visited & reports that he read about the resignation of G. Russell in GALIGNANI'S MESSENGER & that he himself is still mildly ill with a cough.
