tendence, but in dealing with the text confined himself to slight verbal corrections. One generic name, that of Gynocardia, was substituted by him for the barbarous name, Chaulmoogra, adopted by Roxburgh, and this alteration has met with general acquiescence. On the portion of the second edition of the 'Hortus Kewensis' printed after the death of Dryander, in 1810, he bestowed the same attention which had been devoted by Dryander to the earlier portion, and by Solander to the first edition, adding largely to the elucidation of certain Families and Genera. These contributions will be found extracted in the present volume.
In the list of Mr. Brown's works given by Pritzel there occur two: "No. 1365†, Of three species of the natural order Orchideæ, Lond. 1817, 4, 8 pp. 2 tab. col.;" and No. 1366†, Select Orchideæ, ib. 4, 2 pp." both extracted from 'The Journal of Science and the Arts,' which do not properly belong to Mr. Brown, but formed part of a series of papers on Cape Orchideæ, by Mr. Bellenden Ker. These, of course, have not been admitted into the present edition.
I have only, in addition, to return my best thanks to my friends, Mr. Carruthers, and the Rev. W. W. Newbould, for much valuable assistance in reading and comparing the proof-sheets; and to Mr. Carruthers, in particular, for the preparation of the elaborate Index of Names of Plants appended to the present volume.
