at Burman’s extensive library and Seba’s incompar¬ 
able apothecary’s establishment. Then they travelled 
across the Zuyder Zee to Harderwijk, arriving early 
the next morning. 
Harderwijk, a small town in Gelderland, then 
boasted a university, which was greatly frequented by 
foreigners, especially Swedes, wishing to obtain the 
degree of Doctor of Medicine. Here not only Lin¬ 
naeus’s teacher and benefactor, Rothman, but Rosen, 
and most of the then members of the Collegium 
medicum in Stockholm, had obtained the same 
dignity. This may have been the reason that made 
Linnaeus prefer this university to Leyden, which 
undoubtedly could claim to possess more eminent 
professors, both in medicine and natural history. A 
contributory reason may have been that Harderwijk 
did not require long residence, and thus demanded 
less economic sacrifice. 
On the day of arrival, Linnaeus looked over the 
University and called on the Professor of Mathe¬ 
matics, J. H. van Loms. On the 7th of June O.S.— 
18th N.S.—his name was inscribed in the Album 
studiosum of the University, and on the same day he 
was sufficiently and sedulously examined in general 
medicine. He took as his subjects two aphorisms of 
Hippocrates, upon a diagnosis, prescribed for the 
treatment of a case of jaundice, when he, with deep 
learning, encountered all the questions concerning 
doubtful points and arguments; the result being that 
he was declared Candidate of Medicine. His thesis 
already prepared in Sweden, “ Hypothesis nova de 
febrium intermittentium causa ” [New hypothesis as 
to the cause of intermittent fevers] in which he sought 
for the causes of ague in certain parts of Sweden being 
so frequent, by assigning the drinking of clayey water 
as the determining act—he had previously left for 
inspection in readiness for his examination, with Pro¬ 
fessor Jan De Gorter, who returned it on the 19th, 
marked as usual, “ imprimatur.” The same day,
