PREFACE. 



Mr. Douglas re-embarked on the 26th of October, 1829, 

 under the same protection and promises of assistance on the 

 part of the Hudson's Bay Company, which had formerly been 

 so eminently useful to him. Although no advices have as 

 yet been received from him, it is confidently hoped, that 

 under his present circumstances, still greater benefit will be 

 derived by the Society from this enterprise, than from any 

 former expedition of the kind. 



The contributions to the Ornamental Department received 

 from various Public Gardens as well as Private Individuals, 

 Fellows and Correspondents of the Society, both at home 

 and abroad, have also been of considerable importance. Under 

 this head the collection of Chilian Plants discovered and 

 introduced by Alexander Cruckshanks, Esq. and the 

 Mexican Plants raised from the seeds collected by J. G. 

 Graham, Esq. in the Mountains of Mexico, deserve to be 

 particularly mentioned as having furnished many new and 

 beautiful hardy, or half-hardy, species. The Hothouses have 

 been more especially enriched by the Indian Collections 

 transmitted by Dr. Wallich from the Botanical Garden of 

 Calcutta, and presented to the Society by the Honourable 

 East India Company, and also by a considerable number of 

 very interesting plants collected in the neighbourhood of 

 Rio Janeiro, and presented by the late Sir Henry Chamber- 

 layne. To Dr. Wallich the Society is also indebted for a 

 variety of Trees and Shrubs from the Mountains of Nipal, 

 which have proved sufficiently hardy to be placed in the 

 Arboretum.
