Luclolf Ghristian Treviraniis, M.D., Professor of Natural History 

 and Botany, and Quiescent Director of the Botanical Grardens at 

 Bonn, was born at Bremen, on the 10th of September, 1779. His 

 education, which was commenced in the schools of his native town, 

 was continued first in the University of Grottingen, and afterwards 

 at Jena, where he took his degree of Doctor of Medicine in the 

 year 1801. And it was at this early period of his career that he 

 determined to devote himself with all his poAver to the cultivation 

 of science, 



" Ne vita trauseat ceu fumus 

 In auras abit, vel in iluctus spuma," 



as related by himself sixty-one years afterwards ; and perseveringly 

 did he keep to this resolve. He entered upon the practice of me- 

 dicine in his native city, and in 1807 had acquired such a reputa- 

 tion as to be appointed Lecturer in the Lyceum. Bvit in 1812 he 

 moved to Eostock, where he was appointed Professor of Botany, 

 in succession to Link, who at the same time was translated to 

 Breslau, where Treviranus, strange to say, again succeeded him 

 when Link took possession of Willdenow's chair in Berlin. There 

 he remained till 1830, when the retirement of Nees v. Esenbeck 

 from the chair of Botany at Bonn determined Treviranus to re- 

 move to that city as his successor ; and there he remained for the 

 rest of his life, although his frequent ill health obliged him to re- 

 linquish the immediate management of the Botanical Grardens, 

 which had at first formed part of his charge. 



Though active in all branches of botanical science, as is shown 

 in his numerous works and communications to various societies, , 

 Treviranus's attention was chiefly directed to the phenomena pre- 

 sented by living plants, and to the accurate determination of spe- 

 cies. He was well versed in botanical literature, and took every 

 opportunity of adding to his botanical library. His numerous 

 writings afford abundant proof of the extent of his knowledge, 

 and of the acuteness of his critical faculty. Though so eminent 

 a botanist, it has unfortunately happened that the Gresneracean 

 genus dedicated to his name by "Willdenow has since been re- 

 ferred to Acliimenes of E. Brown, so that the name of Treviranus 

 is deprived of an honour so justly its due. He was made a Foreign 

 Member of this Society on the 4th of May, 1830, and died on the 

 22nd of May, 1864, two days before our last Anniversary.
