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 the letter of 20 February 1760Letter L2682 that had just arrived.

Among several minor notes on various plants, Linnaeus goes into some detail to describe the fruit of Cedrela that is not like any other.

Linnaeus admits, with some hesitation, that Patrick BrowneBrowne, Patrick (1720-1790).
Irish. Botanist who made six voyages to
the West Indies. In 1756 he published
The Civil and natural history of
(1756). Correspondent of
might have been very fond of food and drink. He still says, however, that Browne is the absolute expert on American plants. If Jacquin can surpass him, he will really come out on top, but until then Linnaeus holds Browne in high esteem due to what he has done.

Linnaeus does not understand Jacquin’s description of the hermit crab and regrets that there is no specimen available. Neither does he know of anybody on Curaçao who could send one to him.

In reply to the previous letter, Linnaeus means that Onobrychis, found with, Charles de LecluseLecluse, Charles de

of the imperial gardens in Vienna,
professor at Leiden.
, is a rare plant very similar to AstragalusAspalathus is a variety of Genista, according to Linnaeus.

Linnaeus tells Jacquin that he plans to add descriptions of 200 animals and 100 plants as a supplement at the end of part 3 of Systema naturae, 10th editionLinnaeus, Carl Systema
, 10th edition (Stockholm
1758-1759). Soulsby no. 58.
, after the section on minerals [the 10th edition was published in two volumes, “Animalia” 1758 and “Vegetabilia” 1759. The third volume, “Mineralia” was never published]. He invites Jacquin to supply material, but brief, to be added under Jacquin’s name but at the same place. Linnaeus is afraid the book will grow too bulky due to all these additions.

Linnaeus is aware that much is still to be learnt about the animals of America, but he is glad to learn so much about the plants from Browne and Jacquin. Since Jacquin is the later of the two, he is the more reliable of them.

Linnaeus has not received a set of seeds sent by Jacquin and wonders with whom they were sent; he has just got a few (that did not gerinate) and a list of seeds promised.

Linnaeus is eagerly waiting for the new Austrian flora [Linnaeus is presumably referring to Enumeratio stirpium plerarumqueJacquin, Nicolaus Joseph, baron von
Enumeratio stirpium plerarumque,
quae sponte crescunt in agro
Vindebonensi, montibusque confinibus.
Accedunt observationum centuria et
appendix de paucis exoticis
] and asks for a description of the Harpyia eagle, especially its habits. He urges Jacquin to publish his American findings so that they will not be lost to science.

The letter has an abrupt end since Linnaeus has to leave for Stockholm, where he will be for a week.
