Upon it. As a relaxation from his labours, he undertook, in the last 

 year of his life, a long joiirney, and attended the Scientific Meeting 

 held at Turin ; but he did not derive from this journey the anticipated 

 improvement in his health, which gradually failed until his death, on 

 the 9th of September last. He has left a son, Alphonse, well known 

 as the author of several valuable botanical publications, one of which, 

 his memoir on the family of Myrsinea, appeared in our ' Transac- 

 tions.' 



Jens Wilken Hornemann was born in 1770, and studied at the Uni- 

 versity of Copenhagen, where his ' Forsog til en Dansk ceconoraisk 

 Plantelaere' obtained a prize in 1795. In 1798 he commenced a 

 botanical tour through Germany, France and England, and in 1801 

 became lecturer at the Copenhagen Botanic Garden. He succeeded 

 his teacher Vahl as Regius Professor and Director of the Garden in 

 1804, and published in 1807 an 'Enumeratio Plantarum Horti Hav- 

 niensis,' and in 1813 and 1815 a more complete synopsis of the 

 plants there cultivated under the title of ' Hortus Regius Botanicus 

 Havniensis.' In 1819 he wrote a dissertation ' De Indole Plantarum 

 Guineensium.' After the death of Vahl he superintended the pub- 

 lication of the ' Flora Danica,' and several papers by him have been 

 published in the ' Transactions of the Danish Philosophical Society ' 

 and the ' Tidskrift for Naturvidenskaberne,' of which he was one of 

 the editors. His lectures and writings have done much to extend 

 the study of botany in Denmark, and have contributed to maintain 

 the character acqmred for Danish botanists by Koenig, Forskahl, 

 CEder, Rottboll and Vahl. 



Among the Associates we lament the loss of 



The Rev. Robert Francis Bree, who became a Fellow of the Lin- 

 nean Society in 1815, and was placed on the List of Associates in

David Don, Fsq., Professor of Botany in King's College, London, 

 and Librarian of this Society, was born in the year 1800, at Forfar, 

 where his father, an acute practical botanist, had estabhshed a Nursery 

 and Botanic Garden. On his father's being afterwards appointed to 

 the charge of the Botanic Garden at Edinburgh, he attracted the 

 notice of Mr. Patrick Neill, and was enabled to attend some of the 

 classes in that city. His father, however, after a while quitting 

 Edinburgh, he returned with him to Forfar, and received his early 

 training in the Garden there. Subsequently he again visited Edin- 

 burgh, and had charge of the stoves and greenhouses in the esta-
