upSUMMARY

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.
received Linnaeus’s latest letter (presumably 9 October 1769Letter L4278) on 4 November 1769 with Anders Philip Tidström’sTidström, Anders Philip

list, and by chance, on the same day, he sent his mineral samples for Tidström from Vienna. He gives the names of his correspondents in Hamburg and wants Tidström to do the same on his part.

Jacquin will continue to collect material for Tidström. He promises to pay for the transport between Vienna and Hamburg but remarks that that is very favourable for Tidström, whose expense must be much lower.

Jacquin plans to go on with his presentation of rare plants in the Vienna garden (Jacquin refers to the Botanical Garden of the University of Vienna, founded in 1754, his work is Hortus botanicus VindobonensisJacquin, Nicolaus Joseph, baron von

), which will be printed at his personal expense. He has about 50 pictures cut already and some more are in drawings, waiting to be cut. He sends two specimens, Rosa bicolor and Crotalaria incana. Only such plants will be treated that are not yet satisfactorily published, and all will be hand-coloured according to nature. – Jacquin does not know how many plants there will be, but the cost is high. The plates will be published in a loose series as long as it is possible to sell them. No predetermined order of plants is set, and a list of the first ones is given.

Jacquin expresses thanks for the plants received but remarks that all that was promised was not in the letter when it came to him. Additionally, he is very interested in getting duplicates from Linnaeus of the material from the region of Cape of Good Hope, especially Erica, Protea and Leucadendra.

Jacquin offers to publish Genista sphaerica if he gets a specimen in a container with alcohol.

All but one of the small Loasa plants had been killed in the greenhouse, where the pot had accidentally been exposed to dripping water. They do not withstand being sprayed with water. The remaining one gives seeds that may save the species, and Linnaeus will get some of that in due course.

Jacquin has got some containers from a Swede, meant for Linnaeus, but he did not manage to pack them with the minerals in Tidström’s boxes, which were too full already. They will be sent at some future time.

Jacquin has written a treatise on calcium and limestone (Examen chemicum doctrinae Meyerianae de acido pinguiJacquin, Nicolaus Joseph, baron von

tale of the fat acid. And in the summer, Jacquin’s students in Vienna had been using Linnaeus’s Systema naturae for the first time.
