438 Report on the progress of the Horticultural Society, 



On various plants received from Mr. Douglas, by Mr. Bentham, 

 Vol. I, p. 403, and p. 476. 



Besides a great number of Notes or Reports on individual species 

 and varieties. 



Dr. Lindley's most valuable and detailed report, on the effects 

 of the frost of 1839, printed in the 2d Vol. p. 225, was also founded 

 on data, observed by himself at the Society's Garden, or obtained 

 from the principal horticulturists of the country, most of whom are 

 Fellows or Correspondents of the Society. 



The Meteorological observations are regularly inserted in the 

 Transactions. 



The Council would also on this occasion advert especially to the 

 valuable papers on vegetable physiology, which their late President, 

 Mr. Knight, continued to communicate up to within two months of 

 his lamented death, a source of information which every follower of 

 the science must regret to see for ever closed. 



Besides the " Transactions," and the " Proceedings" of the 

 Society, a new edition of the Catalogue of fruits in the Society's 

 garden, with notes on each variety, was published in 1831 ; and 

 the Council have moreover thought it incumbent on them on all 

 occasions to communicate information required by the Fellows 

 of the Society, and to give their assistance in the publication of any 

 work of respectability, being fully persuaded that one grand object 

 of the Society is the dissemination of horticultural knowledge, and 

 that nothing is more contrary to the spirit of the association than 

 jealously to reserve for themselves that which might be more 

 speedily and usefully published by others. It is thus that much 

 which relates to the Society's collection of trees and shrubs, will be 

 found in Mr. Loudon's Arboretum and Fruticetum Britannicum, 

 and observations and experiments made at the Garden have been 

 the groundwork of many of the principles laid down in Dr. 

 Lindley's Theory of Horticulture.
