L4281. Carl LinnaeusCarl Linnaeus (1707-1778). Swedish.
to Johan Otto HagströmJohan Otto Hagström (1716-1792).
Linnaeus has just returned from a visit to Abraham BäckBäck, Abraham (1713-1795).
Linnaeus says that it is difficult to find an observant German who is not born to be a compilator, and is not surprised that Gleditsch has not made observations but has simply written what he has believed. Linnaeus advises Hagström not to include Gleditsch in his writings but simply to say that Gleditsch had written on the same subject but not in such detail.
Linnaeus has not read Gleditsch’s book [Linnaeus refers here to the Vermischte physikalisch-botanisch-ökonomische AbhandlungenGleditsch, Johann Gottlieb
Linnaeus says that his Receptaculum did not exude any sweet juices when the air got colder, but that it certainly became reduced in size in proportion to the warmth in the air.
Linnaeus complains that his publisher has made an error in connection with Helianthus annuus [Linnaeus refers to the remarks made by Hagström in his last letter].
Linnaeus regrets that the seeds didn’t germinate. The same said Pehr KalmKalm, Pehr (1716-1779).
Linnaeus then gives Hagström examples of how he describes plants, and how he shows the printer where to use italics, capitals, etc.
Linnaeus doubts whether a plant that thrives in warmer climates would be rejected by bees in colder ones; it cannot be possible, nature remains the same.
Then Linnaeus answers Hagström’s request about a “winter argument”, and promises to give it some thought but emphasises that it is difficult to find something in a hurry.
Linnaeus praises Hagström’s observations, and says he always reads them with great pleasure.
