18 Notices of European Herbaria. 
of error, and to secure the collection from injury, it was carefully 
revised by Prof. Schlechtendal, while under his management, and 
the specimens attached by slips of paper to single sheets, and all 
those that Willdenow had left under one cover, as the same spe- 
cies, are enclosed in a double sheet of neat blue paper. These” 
covers are numbered continuously throughout the herbarium, and 
the individual sheets or specimens in each are also numbered, so 
that any plant may be referred to by quoting the number of the 
cover, and that of the sheet to which it is attached. The ar- 
rangement of the herbarium is unchanged, and it precisely ac- 
cords with this author’s edition of the Species Plantarum. Like 
the general herbarium, it is kept in neat portfolios, the back of 
which consists of three pieces of broad tape, which, passing 
through slits near each edge of the covers, are tied in front: by 
this arrangement their thickness may be varied at pleasure, which, 
though of no consequence in a stationary herbarium, is a great 
convenience in a growing collection, The portfolios are placed 
vertically on shelves protected by glass doors, and the contents of 
each are marked on a slip of paper fastened to the back, ‘The 
herbaria occupy a suite of small rooms distinct from the working 
rooms, which are kept perfectly free from dust. ! 
Another important herbarium at Berlin, is that of Prof. Kunth, 
which is scarcely inferior in extent to the royal collection at 
Schoneberg, but it is not richor authentic in the plants of this 
country. It comprises the most extensive and authentic set of — 
Humboldt’s plants, and a considerable number of Michaux’s, © 
which were received from the younger Richard. As the new | 
Enumeratio. Plantarum of this industrious botanist proceeds, — 
this herbarium will become still more important. | 
For a detailed account of the Russian botanical collections and | 
collectors, we may refer to a historical sketch of the progress of 
botany in Russia, é&c., by Mr. Bongard, the superintendent of the 
Imperial Academy’s herbarium at St. Petersburgh, published in 
the Recueil des Actes of this institution for 1834,. An English — 
translation of this memoir is published in the first volume of !
