dahlias in France, are given by Mons. Dumont de 

 Courset, in Le Botaniste Cultivateur. 



In 1812, at Paris, M. A. Thiebant de Berneaud, 

 published " Memoire sur la culture des dahlies, &c ;" 

 and in similar floricultural works, Mr. Hogg, Mr. 

 Maddock, and others have written, in this country, 

 upon dahlia culture. 



Figures of different varieties of the dahlia, with 

 some observations on each, have, at various times, 

 been published it the Paradisus Londinensis, the 

 the Botanist's Repository, the Botanical Magazine, 

 the Botanical Register, and other periodicals devoted 

 to flowers. 



An expensive work, entitled "The Dahlia Regis- 

 ter," intended to have been continued annually, was 

 published in 1836. It contained 53 coloured plates 

 of the best varieties then known. No other volume 

 was published. In 1840, Mr. Paxton published "A 

 Practical Treatise on the Cultivation of the Dahlia 

 and Mr. Turner, in 1846, gave to the public his 

 "Practical Observations on the Culture of the 

 Dahlia." 



From all of the foregoing, we have culled the most 

 useful information ; and this amalgamated with, and cor- 

 rected by, our own later experience, will render, we be- 

 lieve, this volume, the most useful and comprehensive 

 authority on the culture of the dahlia that has hither- 

 to appeared.
