able works, will not allow us to enlarge on this favourite topic as we 

 would wish. Nevertheless, we must not omit to mention the names of a 

 few more individuals who are now engaged in raising still higher the bota- 

 nical fame of Germany. Our excellent friend Dr Hornschuch is the pro- 

 fessor of natural history in the university of Griefswald, Prussian Pome- 

 rania, and devotes a large portion of his time to the cultivation of what we 

 consider to be his most favourite pursuit, botany. He has already been 

 mentioned as the author, jointly with Dr Hoppe, of a Tour in the Southern 

 Countries of the Austrian dominions, and is engaged in publishing the 

 Mosses of Chamisso and Spiv and Martius ; but that which will most 

 tend to raise his celebrity, is the " Bryologia Germanica," published in 

 conjunction with Dr Nees von Esenbeck and Sturm. If we differ from 

 these authors in any important particular, it is in their raising, too fre- 

 quently, what we consider to be varieties, to the rank of species, and thus 

 by rendering it impossible to define clearly the characters of the indivi- 

 duals, they add to the difficulty of the tyro in his investigation. The 

 first volume, which includes only those mosses which are destitute of 

 peristome to the capsule, is all that has been yet published. The second 

 we anxiously expect ; and we are rejoiced to hear that Dr Hornschuch 

 has promised to the world a complete Species Muscorum, for which he 

 must be furnished with very abundant materials. This gentleman, too, 

 is a great contributor to one of the many excellent scientific journals of 

 Germany, the " Flora, oder Botanische Zeitung welche Recensionen, Ab- 

 handlungen, Aufsalze, Neuigkeiten und Naehrichten, die Botanik betreffend, 

 entha.lt :" — in fact, an " Annals of Botany," published by the Royal Bota- 

 nical Society of Ratisbon, in weekly numbers. We know of no work 

 better calculated to encourage and diffuse a love of botany than this cheap 

 little work, which has extended to many volumes, having a great deal of 

 original matter and numerous notices, from which we have selected much 

 that has been useful to us in the present article. 



Treviranus of Breslau has gained reputation by his writings on the 

 Sexual System of plants : Reichenbach of Dresden by his " Lichenes Ex- 

 s iccatas," his " Icones Plantarum variorum" " Hortus Botanicus'* and 

 ** Monographia Aconitorum ,-" Lchmann of Hamburg by his admirable 

 monographs of Primula, Nicolianu, and, above all, of the Aspcrijoliue ; 

 Steudel of Efsling by his useful '.' Nomenclaior Botanicus," which has 

 been elsewhere more particularly mentioned by us : Meyer, * G. F. W. 

 of Gottingen, by his " Primitice Flora Essiquebensis ;" and Ernest Meyer, 

 also of the same place, by his Monograph of the Junci, and his " Plantar 

 Surinamensis ;" Roper, of the same town, by his work on the Euphorbia: ; 

 Sturm by his numerous and excellent botanical plates, executed at Nu- 

 remberg ; and, lastly, we shall mention Sivbcr and Helsinborg and Bojer, 

 who have done themselves great credit by their labours in collecting plants 

 in many and distant regions. The former, besides visiting Crete, spent
