After that Linnaeus sent Fredrik HasselquistHasselquist, Fredrik

] is still there, and he will be sent to their colonies [in South America] at their expense. So Linnaeus has not worked for himself but for the public; both the Dutch nation and Linnaeus have profited from these journeys, although the expense has been covered from Sweden.

So Linnaeus had really not expected a refusal from the Dutch regarding Kähler. All he wanted was permission to go there and gather innocent flowers and insects in the wilderness, and Linnaeus thought nobody would refuse that, except maybe the Japanese. It was the more surprising, as the Dutch have contributed so much to science. However, times change, and science follows the political circumstances.

Linnaeus does not want Preis to try to have the issue reassessed. Linnaeus has managed to get money for Kähler to go, and he will go, but Linnaeus will send him to another country in Africa. It does not matter where he goes.

However, Linnaeus does ask Preis to obtain a formal document from the government containing this refusal, a testimony for the future. Thus, nobody can question Linnaeusís care for Kähler, and those who do not think this could happen will have it manifestly documented.

This would be very gratifying both to Linnaeus and to all lovers of science.
