valuable in another point of view, for it contains an arrange- 
ment of all the known Alge ; the Genera with their charac- 
ters, and a Catalogue of Species, with reference to descrip- 
tions and figures, and an alphabetical Index of all Algological 
writers. We trust the author may be induced to treat the 
other Cryptogamic Orders with the same masterly hand.

During the course of the publication of his * Genera 
Plantarum," Endlicher commenced a series of botanical 
plates illustrative of those Genera, under the title of * Icono- 
graphia Generum Plantarum, Vienna, 1838 ;" and whether the 
drawings and analyses were executed by the magic hand of 
Ferdinand Bauer, or by * Zehner," or “ Putterlich" (names 
Which some of the plates bear), they are alike honourable to 
the artists and to the author. Nothing more perfect of the 
kind has ever appeared in any age or country; and it was a 
matter of deep regret with us, that, owing probably to the 
heavy expense attending the execution of such plates, and a 
limited sale, the work was discontinued at the conclusion of 
the first volume (in quarto, with one hundred and twenty- 
five plates, engraved in outline, a little shaded, uncoloured). 
The place of this is endeavoured to be supplied by Dr. 
Schnizlein, who has announced his * Iconographia Familiarum 
Naturalium Regni Vegetabilis delineata, atque adjectis fami- 
liarum characteribus adnotationibusque variis tum scientiam 
tum usum spectantibus exornata." The object of the work 
1$ stated to be the Illustration of all the families of the 
vegetable kingdom, by one or more figures of each, with dis- 
sections; taking Endlicher principally as the authority for 
such families. The number of these is estimated at about three 
hundred and thirty, and each will be so represented. that the 
Whole can be arranged, previous to binding, according to the 
Views and wishes of the possessor. The European examples
