 que cognitorum,' 8vo, Viennae, 1820 ; ' Clavis Agrostographiae Anti- 

 quioris,' Coburgi, 1822; ' De Graminibus unifloris et sesquifloris 

 Dissertatio Botanica,' 8vo, Petropoli, 1824 ; and ' Species Graminum 

 Iconibus et Descriptionibus illustratae,' in three vols, folio, Petropoli, 

 1828, 1829 and 1836. His contributions on the same subject to the 

 Memoirs of the Academy of St. Petersburgh were numerous and im- 

 portant, including a revision of the genera and species of Panicea in 

 the restricted sense of that tribe, of Stipete, of Bambusece, &c. 



In these works he propounded a theory of the structure of the 

 gramineous flower, which although supported with much ingenuity, 

 has met with little acceptation among botanists. But his systematic 

 labours on the family have contributed in no small degree to its elu- 

 cidation, and his patient and elaborate investigations will ensure him 

 a distinguished position among that valuable class of observers who 

 devote themselves to the study of a single famUy of large extent. 



M. Trinius had long been resident at St. Petersburgh, where he 

 became a Corresponding Member of the Academy in 1810, and an 

 Effective Member in 1823. He was also for many years Director, 

 as indeed he was in a great degree the founder, of the Botanical 

 Museum; with which in 1843 he incorporated his own collection of 

 grasses, estimated by M. Meyer to contain from 35,000 to 40,000 

 specimens belonging to 5000 species. These numbers may well be 

 regarded as enormous, when we reflect that M. Kunth's Enumera- 

 tion of the family, hicluding a great number of doubtful species, 

 scarcely exceeds 3000. With such vast resources at his disposal, 

 we may expect from M. Ruprecht, who has been associated with 

 M. Trinius in several of his later memoirs, and who has attached 

 himself particularly to the study of the Grasses, large contributions 

 to our knowledge of this important family. 



M. Trinius was, as we are informed, an intimate friend of Chamisso, 

 and like him mingled a genius for poetry with his botanical pursuits. 

 He was admired for his varied accomplishments and for his depth of 

 intellect, and loved for his amiable disposition and agreeable manners. 

 He died at St. Petersburgh on the 12th of March 1844. 



And lastly we have to lament the death of one Associate. 



Thorms Charles Hope, M.D., F.R.S., V.P.R.S.E. S^c, Professor of 

 Chemistry in the University of Edinburgh, was the son of Dr. John 

 Hope, for many years Professor of Botany in the same University, 

 and was bom at Edinburgh on the 21st of July 1766. On the death 

 of his father in 1786 he became a candidate for the vacant chair, but
