sometimes two or more, so that they contain but 1331 species; and 

 these are published without any systematic arrangement, though 

 accompanied with very complete indices. With the eleventh cen- 

 tury an important change has taken place, and the first 1 10 plates 

 are devoted to the illustration of all the German Grasses, here esti- 

 mated at 402 species. The twelfth century illustrates, in an equally 

 satisfactory manner, a scarcely less difficult family, the Cruciferce. 

 These occupy 98 plates, and embrace 233 species. The following 

 four plates are devoted to the Resedacea. Here are thus an im- 

 mense quantity of plates, and a great number of analyses brought 

 forward in a small compass, and yet so well arranged, as to present 

 no confusion to the eye. Whatever may be thought of the propriety 

 of making, in several instances, so many species upon very slight 

 grounds, the accuracy of these figures, whether of species or vari- 

 eties, cannot fail to throw much light upon this difficult department 

 of botany; and the price is extremely moderate.

The second number of this valuable work has appeared. The exe- 

 cution of the figures is even better than that of the first part, noticed 

 at page 61 of this Journal, and it is no less full of interest and in- 

 formation. We are happy to observe that he has figured several spe- 

 cies from the specimens published by Fries in the ' Scleromycetes 

 Suecise,' on the structure of which he has thrown quite a new light, 

 as in Agyrium rufum, &c. We hope that he will continue this useful 

 practice, as the illustration of described species is of far greater im- 

 portance than the putting forth of new and hastily formed genera.
