show some hospitality to a young naturalist, Linne’s 
eagerness flamed up anew. The Swede proved to be 
Carl Gustaf Dalberg, at that time revisiting Sweden. 
Finally Rolander was recommended for the post. 
From Count C. De Geer, 600 dalers [^15] were 
received for equipment, and provided with instructions, 
he started at the end of 1754 or the beginning of the 
next year. 
Little is recorded of what followed, but he was 
detained by illness at Amsterdam, only getting to 
Paramaribo in June, 1755, which he quitted in the 
following January. Dalberg tried to persuade him 
to stay longer, but he pleaded his weak health, dislike 
of the climate, and weariness of working in the heat. 
Thus Linne’s hopes of Rolander’s success were 
blighted, the only thing he had sent to the Uppsala 
garden being specimens of the Cochineal cactus, 
referred to later; and he complained that “ Rolander, 
that ungrateful pupil, gave him nothing of his 
collecting,” but delivered them to Court Marshal De 
Geer, who afterwards presented Linne with a store 
of rare plants. 
It soon appeared, however, that Rolander was less 
ungrateful than unfortunate. Before long he was 
seen to be disordered in mind. This showed itself 
chiefly in the fact that he brought home some grey 
seeds and said they were pearls, fine pearls, and even 
though their shells were fractured, he guarded them 
as being precious. On other topics he spoke sanely, 
even studying Materia medica in Stockholm, till 
Linne found him incompetent. Afterwards he went 
to Denmark to sell his pearls, which were, however, 
stolen, then he lived in Skane upon charity, and died 
in Lund in 1793. 
One of Linne’s cleverest pupils was Anton 
Rolandsson Martin, who had a long struggle against 
poverty, with experience of suffering, and of dis¬ 
appointed hopes, but found in his teacher a faithful 
helper and comforter. Born in Livland in 1729, he
