OBSEEVATIONS, &c. 



The Herbarium formed, chiefly by tlie late [Append, p. sos 

 Dr. Oudney, during the expedition, contains specimens, 

 more or less perfect, of about three hundred species. Of 

 these one hundred belong to the vicinity of Tripoli ; fifty 

 were collected in the route from Tripoli to Mourzuk, 

 thirty-two in Fezzan, thirty-three on the journey from 

 Mourzuk to Kouka, seventy-seven in Bornou, and sixteen 

 in Haussa or Soudan. 



These materials are too inconsiderable to enable us to 

 judge correctly of the vegetable productions of any of the 

 countries visited by the mission, and especially of the more 

 interesting regions, Bornou and Soudan. 



For the limited extent of the herbarium, the imperfect 

 state of many of the specimens, and the very scanty in- 

 formation to be found respecting them, either in the her- 

 barium itself or in the journal of the collector, it is unfor- 

 tunately not difficult to account. 



Dr. Oudney was sufficiently versed in botany to have 

 formed collections much more extensive and instructive, 

 had the advancement of natural history been the principal 

 purpose of his mission. His time and attention, however, 

 were chiefly occupied by the more important objects of 

 the expedition ; as a botanist he had no assistant ; and the 

 state of his health during his residence in Bornou must, in a 

 great degree, have rendered him unable to collect or observe 

 the natural productions of that country. 



For the few specimens belonging to Soudan, we are in- 

 debted to Captain Clapperton, who, after the death of Dr.-
