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.
wants to make a check on the letters he has received. He has just received one from Linnaeus of 10 September 1761Letter L2961, and a few days previously received another without a given date but written a few days earlier (September 1761)Letter L2962. Previous to that, the last letter from Linnaeus was dated 20 March 1761Letter L2889, answered by Jacquin on 20 May 1761Letter L2912, but no answer has arrived to that letter. He wonders why. He also thanks Linnaeus for seeds.

On Pinguicula, a plant common in the mountains of Martinique, Jacquin is surprised that Linnaeus says he has not received a drawing sent by Jacquin. He points out that Linnaeus referred to that drawing in the letter of 20 March 1761Letter L2889.

Jacquin answers Linnaeus’s questions on Sida trisulcata, Samyda and Casearia; the latter two can not belong to the same gender.

There had been a discussion in Vienna on the number of stamens in Asclepiades, but Jacquin got his sceptical colleagues to take part in a demonstration and showed them the truth, after which there had been a better understanding of the art of botanical examination. The flower seems to be hard to examine, since it flowers for a very short time; Linnaeus has never seen the flower, so Jacquin promises him a dry preparation of the flower and asks to be believed.

Jacquin has not seen Albrecht von Haller’sHaller, Albrecht von

poet, professor of medicine, botany,
anatomy and surgery at Göttingen
1736-1753. Correspondent of Linnaeus.

rariores proveniunt
([Lausanne]
[1760] ).
). – One of the leaves sent by Linnaeus is Rhamnus cubensis, while Jacquin does not remember the other one.

Jacquin sends some prints of woodcuts of drawings of plants, some cut by himself, another cut by an expert after a drawing by Jacquin. Jacquin is not too satisfied with his own talents.

Jacquin has been in the Alps twice this year and seen many rare plants, and he plans to return in April since snow and cold prevent his going before that. He is used to a warmer climate. He is about to publish a work with descriptions of 100 rare plants and an index of 300 (Jacquin refers to Enumeratio stirpium plerarumqueJacquin, Nicolaus Joseph, baron von

in his Austrian flora (Jacquin refers to Elenchus vegetabilium et animalium per AustriamKramer, Wilhelm Heinrich

(Vienna and Prague 1756).
). He also adds a few pictures, as many as he can afford, and follows Linnaeus’’s system.

Jacquin will send material to Johan Frederik GronoviusGronovius, Johan Frederik

in Holland a few months later and will then also send a container of spirit with American flowers in it; Gronovius will be asked to forward that container to Linnaeus. Jacquin gives a list of the species concerned and some advice to Linnaeus on how to proceed to be able to make proper examinations of these specimens when they have been taken out of the preservative fluid. In the same way, also a small herbarium of Austrian plants will be sent. – Jacquin asks for leaves of Laurus cinnamomus and Cassia.

Jacquin has started to publish the work on American plants [Selectarum stirpium Americanarum historiaJacquin, Nicolaus Joseph, baron von
Selectarum stirpium Americanarum

] and has already got proof sheets, one being sent to Linnaeus. He suggests that also Linnaeus should send his material to Jacquin through Gronovius and adds a list of plants that he would like, mainly Gramina and Cryptogamae.

The letter ends with a question on the present opinion in Sweden with regard to Cicuta as a remedy against cancer – many have started to doubt that in Austria – and renewed instructions on the proper way to address letters to Jacquin.
