Jacquin again asks about Linnaeusís attribution of the Salix species, since he is not at all satisfied.
Jacquin also has more questions on Theobroma augusta. Specifically, he asks for advice when a plant agrees with another in the shape of the flower but not of the fruit, while it agrees with a third one in the shape of the fruit alone. He is very much concerned over this state.
Neither have Linnaeusís answers satisfied Jacquin in several other plants (Cyca, Arenaria, Brassica, Convallaria, Convallaria, Curcuma and others), and Jacquin wants more explanations and tells Linnaeus what his own opinion is.
Jacquin repeats the information that the rat, Sciurus glis, steals cow milk from the peasants who keep their cows in the highlands in the summer to get milk for cheese and butter. He does not explain how the theft is performed. He adds that if the rat is kept indoors and fed by men, it lives from cow milk only. It sleeps all winter without taking food and goes back to sleep immediately even if it is waked by force.
Jacquin will shortly send him a list of more plants, which Adolf MurrayMurray, Adolph (1751-1803).
