3 PREFACE. 



is - 



In this Third Volume of the Gardener's Magazine, the reader will 

 find some improvements on the plan of the former Volumes. These 

 are, the accentuation of botanic names ; the indication of generic 

 names as, commemorative, classical, aboriginal, or composed ; and, 

 when specific names are Englished, the literal meaning given. 

 The details and the advantages of these improvements are ex- 

 plained in Vol. II. p. 447. 



Taking a general view of the improvements in gardening which 

 are recorded in this Volume, the leading feature, and one of very- 

 considerable interest in the exotic department, is the mode of 

 heating hot-houses by hot water. Though the invention was made 

 above half a century ago in France, and applied there for artificial 

 incubation, as well as to the hot-houses in the Jardin des Plantes, 

 it does not appear to have been introduced into England till the 

 year 1815, when the house No. 1. in Russel Place, London, was 

 heated in this manner by the Comte Chabannes, and afterwards 

 the hot-houses at Sundridge Park by the same individual, in 1816 

 and 1817. The use of steam withdrew for a time the attention of 

 engineers from the subject of hot water ; but that element has 

 again been resorted to, apparently without any knowledge of what 

 had been already done by others, by Mr. Whale and Mr. Atkinson. 

 Neither of these gentlemen, it appears, was aware of M. Bonne- 

 main's invention in Paris, in 1777, or the Comte Chabanne's oper- 

 ations in London and at Sundridge Park. Mr. Tredgold (p. 427.) 

 has claimed for Mr. Atkinson the merit of having first success- 

 fully applied the hot water system to hot-houses in England ; 

 and, unquestionably, Mr. Atkinson's apparatus of 1822, is more 

 simple than that of the Comte Chabannes at Sundridge Park 

 of 1816, though not more effectual. The details of which the 

 above is the summary, will be found in pages 186. 254. 365. 368. 

 and 423 — 432. ; and further information on the subject, received 

 even since this Preface was prepared for the press, is unavoidably 

 reserved for our succeeding Volume. 



Some most desirable acquisitions to Floriculture are described 

 in the analysis of botanical works in our Catalogue raisonne'e ; 

 and we refer to pages 342. 385., and Vol. II. p. 460., for some 

 Dutch and German practices, which, if adopted in this country, 

 would, at an easy rate, increase the enjoyments of the wealthy 

 who possess gardens ; prove profitable to the tradesman gardener ; 

 and advantageous to the public consumer of garden vegetables.
