art. He supported Swedish artists and
scientists and collected art, books and
natural history objects. He assisted

request [Bruyset to Linnaeus, 29 AprilLetter L2708] for the finished Lexicon Historiae naturalis [Linnaeus refers to the proposal, put forward by CouturierCouturier, (?-?). French.

, that he should publish a “Dictionnaire portatif d’histoire naturelle”. This work was never published].

Linnaeus informs that he has been hard at work with the Lexicon and has found the work more extensive than anticipated, especially as to the minerals, as he has not yet completed his work in this particular field. He had to leave both projects for other requests. He aims to complete the third volume of the Systema naturae during the summer holiday [Linnaeus refers to the Systema naturae, 10th editionLinnaeus, Carl Systema
, 10th edition (Stockholm
1758-1759). Soulsby no. 58.
; the 10th edition was published in two volumes, “Animalia” 1758 and “Vegetabilia” 1759. The third volume, “Mineralia” was never published]. When this work is done he will return to the “Dictionnaire”, which will take more time than he had expected himself, because, if it should be properly done, Linnaeus has to enumerate not only all terms, but also all the names of animals, plants and stones, which is a considerable number.

P.S. Linnaeus asks Tessin to kindly inform the Countess Tessin [Lovisa Ulrika TessinTessin, Lovisa Ulrica (-1768).
Swedish. Countess, wife of Carl Gustaf
] that Linnaeus has limited knowledge about “ärtmeysen” [probably Helianthus tuberosus], except that 1. it ought not to be planted in wet or marshy soil and 2. nor in shadow

Apart from that, the plant is too delicate for our climate.
