LIKNEAN SOCIETY OF LONDON. xli 



March 1826, and published in the 15th volume of its 'Trans- 

 actions.' About the same time Mr. Don also communicated to 

 the Wernerian Society a Monograph of the genus Allitim, which 

 is published in the 6th volume of the Memoirs of that Society. 

 From 1828 to 1837 his time was principally occupied upon the 

 ' General System of Gardening and Botany,' or as it was after- 

 wards called, the ' History of Dichlamydeous Plants,' consisting 

 of four 4to volumes, averaging about 880 pages each. The original 

 intention was, that the work should include all the known species 

 of plants, and that the whole should be comprised in four volumes ; 

 but this being found impracticable, and the publishers receiving 

 little encouragement to proceed, it was abruptly closed at the 4th 

 volvune without its having extended beyond the Dichla/niydecB. He 

 shortly afterwards entered into an engagement to supply the 

 botanical articles of the ' Encyclopaedia MetropoKtana,' which he 

 continued to do till the close of the work, great part of the intro- 

 ductory treatise having been furnished by him, as well as the 

 articles in the alphabetical series, from the middle of the 11th 

 volume to the end of the 12th. In 1842-3 he was employed by 

 the Board of Woods and Forests in naming the trees and shrubs 

 in Kensington Gardens and the Parks, by means of which the 

 names of a very considerable number of species and varieties of 

 woody plants have become familiar to the visitors. He Likewise 

 rendered much assistance to the late Mr. Loudon in the prepara- 

 tion of the various botanical works in which that gentleman was 

 engaged during the last ten or twelve years of his life ; and the last 

 of his botanical laboTirs was the preparation of a supplement to 

 Loudon's ' Encyclopaedia of Plants,' which made its appearance 

 only a few months before his death. He had been suffering at in- 

 tervals during the last two years from disease of the heart, which 

 had latterly prevented him from being present at any of our 

 meetings, at which he had for many years previously been a con- 

 stant attendant, having been elected an Associate in 1822, and a 

 Fellow in 1831. He died at Campden ELill, Kensington, on the 

 25th of February last, in the 58tli year of his age. 



Alexander Erskine, Esq., of Balhall, in the county of Forfar, 

 and Longhaven, Aberdeenshire, became a Fellow of the Linnean 

 Society in 1804, and was also a Fellow of the Horticultural Society. 

 He died, at his residence in Bryanstone Square, on the 17th of 

 November last, in the 81st year of his age, having been for more 

 than fifty years a Fellow of our Society. 



John Harris, Esq., of Exeter, Surgeon, was admitted a Fellow
