Jacquin asks Linnaeus not to judge the Austrian flora by Wilhelm Heinrich KramerísKramer, Wilhelm Heinrich
Jacquin comments on Carduus mollis, which is not quite like Linnaeusís. The same is the case with a Silene species.
Jacquin thinks that Linnaeus has mixed up two species of Erysimum and asks some questions about Ornithogalum umbellatum and Selinum pumilum.
Jacquin gives a long and very vivid description of the small crab Cancer parasiticus. Then, he answers Linnaeusís request for a description of the Harpyja eagle, which he had in a cage in America. Jacquin describes it in great detail, also how he kept it, how he fed it and with what, its favourite foods, hens and monkeys etc.
Jacquin gives short descriptions of nine birds and a mammal similar to a monkey, large as a small cat. It is nocturnally active, herbivore and living in the forest in South America. He does not know its scientific name; the native name is Marta.
Jacquin reports that Amomum Zerumbet is flowering and asks for seeds of Linnaea borealis.
Jacquin has heard that a medal has been cast of Linnaeus and he wants a copy of it. He promises in return a silver medal with Gerhard van SwietenísSwieten, Gerhard van
Twenty-eight seeds of American plants are sent, and the species are listed. Most of the seeds have been sown successfully in the garden in Vienna.
Jacquin sends dried specimens of several plants, among them Cherleria, and asks for seeds and specimens of several species which he enumerates.
Jacquin sends a piece of a magnetic mineral from somewhere in Dominique. He describes the circumstances and the location where he found it. Even the soil from there is a little magnetic.
Jacquin is once more heading for the mountains near Vienna and promises more letters on new plants after he has returned.
Jacquin wants a specimen of Kiggelaria. He offers Linnaeus specimens of Austrian plants, and Linnaeus may just mention what he wants and Jacquin will get it for him sooner or later.
Jacquin gives a complete address to be used by Linnaeus in his letters and ends the letter with a question on two Euphorbia species occurring in the Austrian Alps.
