Denmark. 



The valuable work which Professor Schow has written in the Danish 

 language, upon the Geographical Distribution of Plants, with maps, has 

 already been translated into German, and Professor De Candolle is about 

 to publish a French translation. 



Dr Nolte, an excellent and zealous botanist of Lauenbourg, who, at the 

 expence of the King, has botanized during many years in Holstein and 

 Lauenbourg, is engaged upon a Prodromus Floras Holsatiae-Lauenbour-

 Wahlenberg has edited at Upsal a Flora Suecica. 



Mexico. 

 The important political changes that have taken place in Spanish and 

 Portuguese America seem already to have had an influence upon the li- 

 terature of those countries. Our excellent friend, Mr Barclay of Bury 

 Hill, Surry, has obligingly communicated to us the 1st No. of an import- 

 ant botanical work, which is just printed at Mexico, entitled " Novorum
