Thanks Adanson for the reply and sends the book requested, with an essay Observations meteorologiques. Wants to study the influence of electricity on plant growth and mentions, among other things, “worms” damaging wheat. No annotations except subject headings and “j’ai repondu le 19 juillet 1775.” The draft of the reply is dated “10 juillet 1775.” Discusses the Tremella and Conferva situations in detail. Read with pleasure Corti’s remarks on the animalcula of infusions, some of which appeared new to Adanson, telling how he began to study these under the eyes of Needham in 1745, leaving this study at the age of 48 to work on the encyclopedia. Mentions briefly the “worms” in the cereals and praises Corti’s meteorological observations, suggesting that he add microclimatological data, e.g., soil temperatures, as Adanson did in Senegal. Also present is an early draft of his paper on Tremella [cf. AD 290] and a description of a Chara species from the Tuileries. An undated and unfinished second draft of Adanson’s reply of 4 pp. is also present.
