Linnaeus thanks Nicolaus Joseph von JacquinJacquin, Nicolaus Joseph, baron von
(1727-1817). Dutch. Botanist. In
1755 at the order of emperor Franz I of
Austria he went to the Antilles and
South America. In 1763 he became
professor of mineralogy and chemistry at
Chemnitz, later professor of botany at
Vienna and director of the botanical
garden at Schönbrunn. Correspondent
of Linnaeus.
for a letter of 29 March 1760Letter L2691 that arrived with a number of seeds enclosed.

Linnaeus is especially pleased to have received a branch of Drypis and a very careful description, which allowed him to correct information from Micheli and put this species in the right class. Earlier efforts to obtain this material had not been successful, and Linnaeus again has the opportunity to say that he could not rely on anybody else’s observations. Most of the merit is with Franz von MygindMygind, Franz von
(c.1710-1789). Danish/Austrian.
Counsellor of the imperial court in
Vienna. Correspondent of Linnaeus.
, and Linnaeus will make a note of this fact, with due reference to that man, in part 3 of Systema naturae [Linnaeus refers to the 10th edition, 1758-1759Linnaeus, Carl Systema
, 10th edition (Stockholm
1758-1759). Soulsby no. 58.
, which was published in two volumes, “Animalia” 1758 and “Vegetabilia” 1759. The third volume, “Mineralia” was never published].

After again expressing his gratitude to Mygind in a very flattering manner, Linnaeus comments on Johann Sigmund Valentin PopowitschPopowitsch, Johann Sigmund Valentin
(1705-1774). Austrian.
Philologist and natural scientist,
professor at Vienna.
, a scholar in Vienna, who had written many unfriendly or even hostile texts concerning LinnaeusLinnaeus, Carl , Linnaeus wonders why Popowitsch is so angry with him, and he even asks Jacquin to try to make Popowitsch change his attitude.

Linnaeus goes on to comment on some of the plants that Mygind had sent. He wonders where Mygind had managed to collect them.

The letter ends with thanks for seeds that Linnaeus had tried to get from other sources but in vain. He hopes they will grow into plants. A couple of detailed comments: Mr Barech should send seeds before they get too old and lose their ability to grow. Jacquin should have fed the lizard with insects and small amphibians that should have kept it alive. At Uppsala, the winter ice on the rivers broke up on April 23, the white wagtail, Motacilla alba and a frog, Rana horaria, have been seen, and the hazel, Corylus, snowdrop, Galanthus and coltsfoot, Tussilago, are flowering.
