APPENDIX. 309 



that before their marriage he would travel for three years, 

 in order to acquire that reputation to which he was so 

 well entitled to aspire. Linnaeus took his departure for 

 Leyden, where the reputation of Boerhaave * was then 

 attracting a crowd of disciples. He reached this town 

 without resources of any kind ; but the great Dutch phy- 

 sician knew how to appreciate the stranger, and through 

 his means he was soon made known to a rich amateur 

 passionately fond of natural history. This generous 

 patron threw open his collections and his library to the 

 young Swede, who, in testimony of his gratitude for these 

 favours, immortalised the name of his benefactor in the 

 title of one of his first works.f At Leyden, Linnasus re- 

 ceived the degree of Doctor of Medicine, after which he 

 visited England and France. It was during one of his 

 two visits to Paris that he contracted that friendship with 

 Bernard de Jussieu, of which his correspondence affords 

 numerous proofs. 



On his return to Sweden, Linnaeus did not at first 

 meet with the reception which ought to have been 

 awarded to his already celebrated name ; but at length, 

 through the good services of De Geer J and the Count 



* Boerhaave, who was born at Voorhout in 1668, and died in 

 1738, has left a name celebrated in the annals of medicine. His 

 reputation was so great, that letters were sent to him from India and 

 America, bearing the sole address of Boerhaave in Europe. He 

 left a large number of works, which, even at the present day, possess 

 some points of interest from the efforts which he made to reconcile 

 the vitalism of Hippocrates with the chemical views of Sylvius, and 

 the solidism of Hoffmann. 



f This work was entitled Hortus Cliffortianus ; Cliffort being 

 the name of his rich and generous friend. 



J De Geer, who was born in 1720, and died at Stockholm in 

 1778, belonged to a baronial family in Sweden. He devoted the 

 large fortune which he possessed to the promotion of science and to 

 the aid of the unfortunate. From his youth he had been an ardent 

 entomologist, endeavouring to follow in the steps of Reaumur.
