I747i Thefe authors, as alfo L. Ge^^ard., 



in his Flora Galh provincialis, Paris 1761, preferve 

 the natural generkd charaUen of Linn^^us almoft 

 entire through their fyftems ; and the latter writer 

 has, with fome variations, taken the 'orders of a 

 natural method, conftruded by 5. Juffieu, for his 

 daffes. Haller alfo planned, and brought to 

 great perfection, a method of this kind, as is 

 exhibited in his Enumeratw Stirpium Helvetia ^ 

 1742, and in the Hortus Gottingenfis, ^ISZ-* which 

 he has fince ftill more elaborated, in a work of 

 infinite labour and merit, the Hijloria Stirpium 

 Helvetia, ^ torn. fol. 1768. 



LiNN^us himfelf very early attempted a na- 

 iural method ; but it is evident he thought there 

 were too many links wanting in the chain, to ren- 

 der it the readied guide to botanical fcience; 

 fince he foon deferted it, although he continued 

 to improve it to the laft : however he only reduced 

 the genera into orders, but did not venture fo far as 

 to form the clajfical part of a fyftem on that plan. 

 The prefent learned and indefatigable profelTorDr. 

 Hope, at Edinburgh, whofe zeal and fuccefs in 

 cultivating and difrufing the principles of the 

 hinnaan fyftem are well known, has conllru6led 

 perhaps the moft elaborate attempt of this kind 

 that the botaniils have ever feen. We join with 

 many others in wifhing that he may be enabled to 

 give it all that perfection which may encourage 

 him to prefent it to the public. 



Methods have alfo been formed from the dif-
