Ruf VISION des Graminies. — Professor Kunth has announced a new con- 

 tribution to botanical science, entitled Revision des Graminies, being an en- 

 largement of what appeared in his Nova Genera et Species Plantarum Avie- 

 ricancB Septentrionalis. The introduction will contain some original views 

 respecting the organisation of this most useful class of vegetables, establish- 

 ing their relation with others, and discussing the opinions previously enter- 

 tained on the subject. The author will then notice the generic characters, 

 point out those which are best established, and add some new ones resulting 

 from his own observations. This introduction will be followed by the com- 

 plete genera. The work will be illustrated by 100 finely' coloured engrav- 

 ings, and, with the descriptive text, will form a folio volume of the same 

 size as the Nova Genera and the Mivwses. {For. Quart. Rev., Jan.) 



Casual Botany, or an Elementary Treatise descriptive of the Changes of 

 Plants, by D. Bishop, is publishing by subscription in 1 vol. 8vo. Is. Sub- 

 scriptions are received by Mr. Wright, agricultural bookseller, Haymarket. 



Petnficata Suecana Formationis Cretacecs has lately been commenced by 

 Professor S. Nilsson of Lund. Professor Nilsson is already advantage- 

 ously known, both in his own country and abroad, as an eminent naturalist, 

 and has added not a little to his fame by this work. A knowledge of the 

 petrifactions is necessarily of great importance to the students of geological 

 science ; and the author has, in preference, chosen those of the cretaceous 

 formation, as having been (though they constitute a number of about 200 

 species) least examined by previous authors. The plates are executed with 

 great care, so as to give a clear idea of each species, and the descriptions 

 are concise and accurate. The continuation of this work will be anxiously 

 looked for by all the lovers of this interesting branch of science. (For, 

 Quart. Rev.) 



BakeweWs Geology is reprinting in the United States, under the direction

 English language." — S, T. Jaih 26. 1829.
