IN enumerating the friends with whom Humboldt was most 

 intimately associated during his sojourn at Paris, we shall first 

 direct attention to those from whom he derived assistance in 

 the publication of his great works. 



Aime Bonpland. A biographical sketch of Humboldt's 

 fellow-traveller has already been given in the Appendix to 

 the first volume of this work. 



Willdenow came to Paris only for a short time while 

 assisting in the botanical department of the work. His assist- 

 ance seems to have been confined principally to the classifica- 

 tion of the plants collected in South America; in consequence 

 of his premature death, some of the plates lie had prepared 

 were withdrawn from publication. 



Jabbo Oltmanns, born at Wittmund, East Friesland, on May 

 18, 1783, came to reside at Berlin in 1805, and devoted him- 

 self exclusively to geographical and astronomical calculations. 

 He was at first commissioned by Humboldt with the reduction 

 of single sets of observations, and was afterwards induced to 

 remove to Paris, where he was occupied till 1811 in editing the 

 4 Eecueil d'Observations.' During this period he also contributed 

 various mathematical papers upon geographical subjects to- 

 Zach's f Monatliche Correspondenz ' and Bode's ' Jahrbucher.*
