with the expKcation of the natural system, will also aid in facilitating the 
researches of the botanical student ; and of the many detached dissertations 
each possesses its peculiar interest and importance. 
In speaking of the arrangements for the ensuing season, suffice it to say, 
that it is intended to adopt all available means for maintaining the interest ^ 
of the publication. The different modes of constructing plant-houses which 
have resulted from the increased attention that has recently been devoted 
to the subject, will form a subject for early discussion. The conditions 
place horticulture on a level with other acknowledged sciences, and its 
connexion with common chemistry, have further to be explained and enforced 
in the numbers which more immediately follow ; the usual care being still 
bestowed on whatever other essays may be admitted. Simple and elegant 
designs for small flower-gardens, such as are usually attached to limited 
villa-residences, have been prepared, and will be forthwith issued. A con- 
siderable number of drawings are also in readiness, the subjects and artistical 
finish of which are unquestionably better than any which have been hereto- 
fore supplied. 
In conclusion, the Editor wishes to state his intention of making each 
future volume, as far as possible, complete in itself, and of avoiding references 
to preceding volumes. He does this to meet the wishes of those who would 
willingly subscribe to the work, but for the fear of finding it useless unless 
in possession of the preceding numbers.
