nuscript of the Supplementum Plant drum in our posses- 

 sion. Ehrhart superintended the printing of this work, 

 and made some alterations in the manuscript, traces of 

 which are perceptible in the affected Greek names, given 

 to some species of Carex, Mespifus, &c, as well as in 

 their sesquipedalian specific characters. But he had intro- 

 duced his own new genera of Mosses; which the younger 

 Linnaeus thought so alarming an innovation, that he or- 

 dered the sheet which contained these matters to be can- 

 celled. We are possessed of a copy, which shows the 

 genera in question to be almost all well founded, and 

 what are now, under Hedwig's sanction, generally received, 

 though by other names. The descriptions of Ehrhart are 

 precise and correct, though his terminology is exception- 

 able, full of innovations, and crabbed expressions. Two 

 years, almost immediately preceding the death of the 

 younger Linnaeus, were spent by the latter in visiting En- 

 gland, France and Holland, and were employed to very 

 great advantage, in augmenting his collection of natural 

 productions, as well as his scientific skill. During this 

 tour, he attached himself strongly, through the medium 

 of his old friend Solander, to Sir Joseph Banks ; and 

 while in France, he almost planted, or at least greatly ad- 

 vanced, a Linnaean school in that kingdom. He had 

 scarcely resumed his professorial office at home, when he 

 was unexpectedly taken off, by an acute disease, in his 

 forty-second year. Of the talents and performances of 

 his successor Thunberg, who still with honour fills the 

 chair of the Rudbecks and the Linnaei, we have already 

 spoken. Dr. Swartz is the Bergian professor of Botany 

 at Stockholm. The Transactions of the Upsal Academy, 

 founded by the younger Rudbeck, are continued occa- 

 sionally ; and those of the Stockholm one, whose founda- 

 tions were laid by Linnaeus, are published regularly. Both 

 are from time to time enriched with botanical communi- 

 cations, worthy of the pupils of so illustrious a school. A 

 veteran in botanical science, Professor Retzius, still pre-
