120 BOTANICAL INFORMATION. 
will, whenever it is practicable, be taken from original draw- 
ings after nature; the rest, it is acknowledged, must be 
borrowed, and carefully selected from the most approved 
works, but not without a thorough revision. Such figures will 
appear as shall not only illustrate the botanical character, but 
exhibit the aspect and appearance of the entire plant; they 
are to be partially coloured, and a preference will always be 
assigned to useful and officinal species, if they are sufficiently 
characteristic. "The number of plates is intended to be 
three hundred and sixty; to be accompanied with text, 
giving the distinctive character of the family in Latin and 
German, and short observations on the essential and other 
characters, as well as a summary of the species. The work 
is to appear in Parts, each of twenty Plates, quarto, and, as 
much as possible, in systematic order, or at least in such a 
manner that one or more entire groups will be completed in 
each. The author assures us that the materials are for the 
most part prepared, and that, unless from some unforeseen 
obstacle occurring, there will be nothing to hinder the publi- . 
cation of three or four Parts (sixty or eighty Plates) annually. 
Such a work has been long a great desideratum ; and, judg- 
ing from the execution of the two first Parts, which are now 
before us, it is every way worthy of encouragement; while 
the very moderate price (two rix-dollars per Part) does 
not preclude botanists, even of limited income, from being 
purchasers. The Cryptogamic plates are very beautiful. In 
the two Parts which have appeared, examples of the fol- 
lowing families are given. Part I. Diatomacee, Nostochine, 
Confervacee, Characee, Ulvacee, Floridee, Lichenes, Gym- 
nomycetes, Hyphomycetes, Gasteromycetes, Pyrenomycetes,
