Some particular fiimilies and genera have been examined in 

 recent times with the most perfect care, and the science has 

 thus been extended. 



The Fungi have been represented in good plates by 

 Augustus John George Charles Batsch, professor at Jena, 

 who died 1802, (Elenchus Fungorum, Halle 1783, 1784) ; 

 by BuUiard, (Herl)ier de la France, div. ii. 1791, in 

 folio) ; by Jacob Bolton, (History of Funguses growing 

 about Halifax, vol. i. iii. suppl. tab. 1, — 182, Huddersfield 

 1788, — 1791, quarto); and by James Sowerby, (Coloured 

 Figures of English Mushrooms, n. i — 29, London 1799 to 

 1814, folio.) The scientific knowledge of Fungi and their 

 genera was first established by Henry Julius Tode, clergy- 

 man in Mecklenburgh, who died 1799, (Fungi Mecklenbur- 

 gensis Selecti, fasc. 1. 2. Luneburg 1790, 1791, quarto.) He 

 was followed by Christ. Henr. Persoon, whose system was 

 long the only one ; (Synopsis Methodica Fungorum, Gottin- 

 gen 1801, octavo ; Observationcs Mycologicae, vol. i. ii. 

 Leipzig 1796, 1798.) J. B. von Albertini and L. D. von 

 Schweinitz extended the knowledge of species ; (Conspectus 

 Fungorum in Agro Nicskiensi crescentium, Leipzig 1805, oc- 

 tavo.) But Henry Frederick Link (Berlin Magazin, iii. 

 s. 1 — 42, vii. s. 25 — 45), and C. G. Nees von Esenbeck 

 (Das System der Pilze und Schwamme, Wurzburg 1817, 

 quarto), were the founders of entirely new views and divi- 

 sions of these families. 



Our knowledge of the Algae was chiefly extended by Al- 

 bert Wilkelm Roth, physician at Vegesack ; (Catalecta Bo- 

 tanica, fasc. 1 — 3, Leipzig 1797, 1806.) Afterwards John 

 Peter Vaucher, clergyman at Geneva, examined the fresh 

 water Confervae, and divided them into natural genera ; 

 (Histoire des Conferees d'Eau douce, Geneva 1803, quarto.) 

 Lewis Weston Dillwyn published excellent plates of the 

 same, (Synopsis of the British Confervae, fasc. 1 — 20, Lon- 

 don 1802, and following years) ; and J. A. P. Ducluzeau de- 

 scribed them as they grow in the south of France, (Essai sur 

 THistoire Naturelle des Conferves des Environs de Montpel-
