Has obtained Peter Huber's paper on "the natural history of the humble-bees" for the Linnean Society and relates some of its principal discoveries; Huber is the son of William Huber of Geneva who published an "ingenious" work on hive bees five years ago including discovery that the queen bee is impregnated out of the hive whilst on the wing and that it is fatal to the males. Huber intends to publish further observations on bees in a second volume, including on the small pouches between the segments on the undersides of the abdomen, in which wax is inserted, and has also observed that the "yellow matter" found on the legs of bees is "bee bread", as discovered by John Hunter [(1728-1793), surgeon and anatomist] before him, but Huber found that this was known to an "old English author on bees which was translated early in [the eighteenth] century into German".

Grateful for Smith's assistance in helping him through France and during his "exile" intends to work on framing much better characters for the division of 'Phalaena' [moths]. Unable to give an account of [Edmund] Davall. Comments that "our revolution" has passed off without bloodshed [French invasion of Switzerland], however at the first moment of its revolt every Englishman except himself left Lausanne as it was expected that the [French] would attack, forcing the cantons to gradually fall off [from the Swiss Confederation] and leave Bern at the mercy of the French. Asks whether [William] Kirby has published on bees as was being reported before leaving England.

Staying with [Edmund] Davall in Orbe, gives a detailed account of Davall's current condition and its history. Believes Davall's condition to be more epilepsy than paralysis and to have had its immediate cause in overwork and overeating from the delusion that he was threatened with a consumption. Detailed description of Davall's fits, has been prescribed powder of valerian root with a little musk to be taken 3 or 4 times a day, has also been treated with "calomil bark" and "flores zinci". Davall experienced much uneasiness having only heard rumours circulated by the French as to the condition of England, has been relieved to hear of the efforts of English resistance. Believes Davall will recover. Comments on the beauty of the area around Orbe. Hopes to send a work by Linnaeus he found in Bern, Switzerland.

Update on [Edmund] Davall's health, which has become more settled with only one partial attack in the last 13 weeks. Davall's physician has prescribed "pills of asafoetida" but finding them too heavy Clark suggetsed Davall take gentle doses of opiates to ease his irritability which also had the benefit of easing his constipation. With [Peter] Hubert has been correcting the paper on bees, comments that the style is heavily influenced by [René Antoine Ferchault de] Réaumur [(1683-1757) French scientist]. Comments on the pleasing appearance of the Alps now that the snow has melted. Is hopeful of obtaining a passport for France from Mr Pitch of Geneva, for which he wrote a piece on veterinary co[lleges] for the "Bibliotheque Brittanique". If disappointed shall return to England via Germany.

Relates events of [Edmund] Davall's death, which occured 26 September 1798. Davall had been confined to his bed for the last three weeks, describes his health in the run up to his death. Died as the apothecary was applying sinasims [mustard plasters] to his feet. Mrs Davall very miserable at her loss. Shocked by Swiss custom to dress and bury the dead in their best clothes, believes it is strongly insisted on by the lower classes. Davall has left Smith his Herbarium. Clark concerned that Davall's "splendid collection" of books shall be a heavy burden to the family in the current distressed condition of Switzerland and Europe. As he has no prospect of getting to France he shall shortly to return to England, having been away 14 months. Hubert sending his paper on bees soon.
