18 MARTIUS ON THE BOTANY OF BRAZIL. 



lian Naturalist, with a moderate salary. He accompanied M. 

 Von Olfers, in 1819, on a journey through the provinces of 

 Minas Geraes and S. Paulo, and afterwards in the southern 

 provinces of St Catharine, S. Pedro do sul, or Rio Grande, 

 and Monte Video, which he traversed in all directions, and of 

 which country he investigated not only the Botany, but the 

 Geology. The extensive and well prepared collections that 

 he sent to the Royal Museum at Berlin, prove his great dili- 

 gence as well as talents ; and it is painful to relate, that after 

 all his laudable exertions, he was not able to return to his 

 native country, but perished in Rio Doce, some say while 

 bathing, others by assassination. 



No botanist, who has trodden the soil of Brazil, has ever 

 so thoroughly examined the country, and in such various di- 

 rections as Sellow, and it were most desirable for the interests 

 of science, that the papers which are in the hands of his friend 

 and fellow-traveller, M. Von Olfers, should be communicated 

 to the scientific world. Many of his discoveries have been pub- 

 lished by Professor Link, in the Hortus Berolinensis, (1821, 

 1827, 1833,) and by Chamisso and Schlechtendal in the Lin- 

 naea. Sprengel also has described many of them in his Neuen 

 Endeckungen, 1820, and in his edition of the Sy sterna Vege- 

 tahilium; and Mr Lessing, numerous Compositae in the Lin- 

 ncea^ and in the Synopsis Generum Compositarum, as M. De 

 CandoUe has also in the fifth (and following) volumes of the 

 Prodromus Syst Veget.; but a still greater number remain. 

 Indeed the herbarium left by this indefatigable but unfortu- 

 nate botanist and traveller, amounts to 10,000 species ! and 

 by his will, the first specimen of every species is to be depo- 

 sited in the Royal Berlin Herbarium ; the second in that of 

 M. Von Olfers, and the third, in M. Kunth's. 



Another Naturalist, whose exertions for the Flora of Brazil 

 have secured him an immortal name, is M. Aug. de St Hi- 

 laire. He left France for Rio in 1816, in the suite of the 

 Ambassador, the duke of Luxemburg, and returned in 1822. 

 The collection is estimated at 7000 species. His first journey 

 was partly in company with M. Von Langsdorff, to the mining
