Circumstances of a "cruel war" cuts him off from Smith's "fortunate homeland, fair and free cradle of the liberal arts". Sends through the Stockholm Academy [of Sciences] his new edition of a work by "the divine Linnaeus" [probably fourth edition of "Philosophia botanica"], which he has dedicated to the Linnean Society. Nothing "more fervently desired by all good men and scholars than the resumption of trade with England"; keen to receive the latest additions to [John] Sibthorp's work edited by Smith ["Flora Graeca"].

All students of botany here dismayed to be cut off from contact with British scholars. Has dedicated his new edition of Linnaeus' "Philosophia botanica" to the Linnean Society and is sending it via Hornemann of Copenhagen; currently unable to send his "Historia rei herbariae" (1807-1808).

Commends his friend, the son of Hagen of Königsberg, to Smith; wishes he could accompany him to Britain to study the treasures there. Requests news of Smith's studies and [Sir Joseph] Banks' old age.

Hopes Smith receives the treatise he is sending [probably "Plantarum Umbelliferarum denuo disponendarum Prodromus" (1813)], asks that the second copy be sent to [Samuel] Goodenough and that he be sent specimens of any plants he is lacking from that family.
