194 Linnean So&iety. [May 24, 



made the botany of the Russian territories the great object of his 

 study during the remainder of his life ; and from the Garden at Dor- 

 pat which he greatly improved, in conjunction with that of St. Peters- 

 burg, the rarer forms of Caucasian and Siberian vegetation have 

 been distributed throughout the rest of Europe. In 1826 he under- 

 took a scientific mission to the Altai, and a winter journey of five 

 weeks brought him to Barnaul, whence on the approach of spring 

 he extended his researches into the mountains as far as the frontiers 

 of China, while his pupil Charles Anthony Meyer examined the 

 Kirghisian Deserts to the westward, and Von Bunge, who has since 

 succeeded him in the Chair at Dorpat, visited the eastern parts of 

 the Altai. The botanical results of this important journey were 

 given to the world in two separate publications ; first, the ' Flora 

 Altaica,' 4 vols. 8vo, Berlin, 1829-1833, the joint production of 

 Ledebour, Meyer and Von Bunge ; and secondly, ' Icones Plantarum 

 novarum vel imperfecta cognitarum, Floram Rossicam, imprimis 

 Altaicam, illustrantes,' 5 vols, fol., Riga, 1829-1834. These works 

 are justly described as forming an epoch in the descriptive, systematic 

 and geographical botany of the Russian empire ; and were accom- 

 panied by an account of his ' Reise durch das Altai-Gebirge,' Berlin, 

 1829, 2 vols. 8vo, which is full of valuable information on geography, 

 geognosy, botany, ethnography and statistics. In 1836 he became 

 Professor Emeritus and quitted Dorpat for a milder climate, which 

 he sought first at Odessa, afterwards at Heidelberg, and finally duiing 

 the last eight years of his life at Munich. In this retirement he 

 commenced and carried to a conclusion, only a few days before his 

 death, the last and greatest of his works, his ' Flora Rossica, sive 

 Enumeratio Plantarum in totius Imperii Rossici provinciis Europaeis, 

 Asiaticis et Americanis, hucusque observatarum,' Stuttgard, 1842- 

 1851. In this, as in his previous works, he adopted the Linnean 

 system of classification, and showed in working out the details 

 great accuracy of observation, a high degree of precision in his 

 characters and descriptions, and much critical research. He died at 

 Munich on the 4th of July last, in consequence of long- continued 

 disease of the heart. His election into the Linnean Society dates 

 from 1845. 



Of the personal history of Jules Cesar de Savigny, but few parti- 

 culars have been obtained. A member of the Scientific Commission 

 which accompanied the French army into Egypt, he attached him- 

 self more particularly to the study of the invertebrated animals, 

 and especially distinguished himself by his memoirs on Annelida 

 and Ascidia, published along with numerous others on almosl
