a lot of rare seeds that he collected during his mission in Tartary, near the Urals. Bielke now sends these seeds to Linnaeus. They are relatively old, 5-6 years, so he advises Linnaeus to sow them densely, as the fertility is probably reduced. Bielke would like Linnaeus to put aside seeds for him from Papilionaceae, so he can create a collection of them, just as he has done with Gramina.

Together with these seeds Kalm encloses a paper cone containing new seeds that he has received from good friends. Among others, there are seeds of Lathyroides Messerschmidii. Bielke would love to have seeds of them, too. The seeds of Pulsatilla deserve special care, as they are extremely rare.

[Through Kalm] Bielke asks Linnaeus to use his influence to make the following Russian professors members of the Royal Swedish Academy of Sciences [Kungliga Svenska VetenskapsakademienKungliga Svenska Vetenskapsakademien,

. They are all contributors to the collections Linnaeus will receive later this year.

P. S. 1. Kalm mentions that Bielke wants to emphasize that Siegesbeck is a real gentleman and a true friend who has contributed more than anybody else to the collections sent to Linnaeus.

P. S. 2. Bielke would also recommend Heinzelmann for a membership. As a member he would be even more willing to share with Linnaeus his enormous collections, not only in botany but in all fields of natural history.
