naturalist. Linnaeusís student. Linnaeus

flowers. He was one of the tutors of

thanks Linnaeus for his letter of the 5 March 1773 [this letter has not come down to us], and for the information that the insect he enquired about was in fact Pediculus apis [see Hagström to Linnaeus, 4 January 1773Letter L4788].

Hagström has once again been confirmed in his belief regarding the effect of some remedy on dysentery, having treated two patients so severely afflicted that their faeces were full of blood. Hagström gave them two doses of powder to be taken once daily on a spoon together with a warm beverage. Already after the first powder their condition had improved.

, writes Hagström, had a live marten, Mustela martes, that Hagström often observed. Among other characteristics, the marten slept deeply. Huntsmen had told Hagström that, indeed, they could come across martens sleeping in the forest and could approach quite close without waking them.

[there were no third editions of these works]. Salvius had profited to 100 percent on these books and thus another printer might also do the same.

Spring is arriving. Hagström is amused by Anders SparrmanSparrman, Anders (1748-1820).
Swedish. Naturalist, physician and
traveller. Disciple of Linnaeus. In 1765
he went on a voyage to China and in 1772
to the Cape of Good Hope, where he
served as a tutor. Later the same year,
Sparrman went on James Cook´s
second voyage as assistant naturalist to
Johann Reinhold Forster and his son
Johan Georg Adam Forster. After his
return to Sweden in 1776 he was
appointed keeper of the natural
historical collections of the Royal
Swedish Academy of Sciences in 1780. In
1787 he participated in an expedition to
West Africa. Practicing physician in
Stockholm. Author of several works, the
best known of which is his account of
his travels in South Africa and with

P.S. Hagström urges that the School curriculum should be reformed at all secondary schools. Teaching in natural history was now dormant at the secondary school in Linköping; nobody was reading the subject. Hagström suggests that Linnaeus should work through Ulrik SchefferScheffer, Ulrik (1716-1799).
