of defining them. This addition was very necef- 

 fary, as the number of plants fynonymed in this 

 volume amounts to near 2,500. We conclude 

 with Gefnefs opinion of this work, in a letter 

 to the celebrated Haller : " Opus fane egregium 

 " et acerrimi Judidi, nec minoris eruditionis, quo dif- 

 " ficulter hotanicus carehit. — Mihi perpkcet ah eo in 

 " nominibus fpecierum notas earum ejfentiaks exhiheri^

 This work is a very large illuftration of the fecond 

 part of the Fundamental from aphorifm 53 to 78, 

 and contains a compendious and ufeful view of 

 all the lyftems of botany, or methods of clafTing 

 plants, both general and partial, from Cafalpinus^ 

 in 1583, who is confidered as the inventor, to 

 LiNNi5:us himfelf in 1735. To the generical 

 name in every fyftem, he has added that by which 

 it {lands in his own, which is a great advantage 

 in the ufe of this book. A new edition, with 

 the requifite additions, would be very acceptable 

 to the public even now. The fyftems at large 

 that are difplayed in this book, are thofe of C^fal- 

 pinus^ Morifon^ Ray^ Knaut^ Herman^ and Boerhaave^ 

 founded on the fruit : Rivinus^ Ruppius^ Ludwig^ 

 and Knaut^ on the number of petals in the flower :
