412 NOTES TO BOOK XVI. 



Mr. Lindley "S recent work, The Vegetable Kingdom, 

 (1846), may be looked upon as containing the best view 

 of the recent history of Systematic Botany. In the Intro- 

 duction to this work, Mr. Lindley has given an account 

 of various recent works on the subject; as Agardh's 

 Classes Plantarum (182Q ; Perleb's Lehrbuch der Natur- 

 geschichte der Pflanzenreich (1826) ; Dumortier's Florula 

 Belgica (1827) ; Bartling^s Ordines Naturales Plantarum 

 (1830); Hess^s Uebersicht der Phanerogenischen Naturli- 

 chen Pflanzenfamilien (1832) ; Schulz's Natlirliches System 

 des Pflanrenreicfts (1832) ; Horaninow's Prima? Linece 

 Systematis Naturce (1834); Fries's Corpus F lor arum pro- 

 mncialium Sueciw (1835) ; Martins's Conspectus regni Vege- 

 tabilis secundum characteres morphologicos (1835) ; Sir Ed- 

 ward F. Bromhead's System, as published in the Edinburgh 

 Journal and other Journals (18361840) ; Endlicher's 

 Genera Plantarum secundum ordines naturales disposita 

 (1836-1840) ; Perleb's Clams Classicum Ordinum et Fami- 

 liarum (1838) ; Adolphe Brongniart's Enumeration des 

 Genres de Plantes (1843) ; Meisner's Plantarum vascu- 

 larium Genera secundum ordines Naturales digesta (1843) ; 

 Horaninow's Tetractys Naturae, seu Systema quinquemembre 

 omnium Naturalium (1843) ; Adrien de Jussieu's Cours 

 Elementaire d^Histoire Naturelle : Botanique (1844). 



Mr. Lindley, in this as in all his works, urges strongly 

 the superior value of natural as compared with artificial 

 systems ; his principles being, I think, nearly such as I 

 have attempted to establish in the Philosophy, Book vin., 

 Chapter ii. He states that the leading idea which has 

 been kept in view in the compilation of his work is this 

 maxim of Fries : " Singula sphsera (sectio) ideam quandam 

 exponit, indeque ejus character notione simplici optime
