in Public Gardens and Nurseries. 519 



clature would soon become general among every class of persons who paid 

 any attention to trees and shrubs. 



It will not be denied, we think, that, in the Arboretum Britanntcum, we have 

 attained as great a degree of correctness in nomenclature, as can well be done 

 with the existing state of living specimens in this country ; and we have, 

 therefore, no hesitation in saying that it would be a great improvement in 

 what may be called the practical nomenclature of the trees and shrubs of 

 Britain, if that given in our work were followed. Let it be observed, 

 that we have given no new names, but merely selected one as preferable, 

 from the numerous synonymes already applied to the same plants ; and, 

 therefore, we are not asking the public to adopt names which we have coined, 

 but merely to agree in all adopting the names which we have selected from 

 those already in use. 



Now, in order to promote the application of our selected names as much as 

 lies in our power, we make the following proposals to nurserymen, and the 

 curators of public gardens : — 



1. To adopt our nomenclature for their hardy trees and shrubs. 



2. To print a catalogue of them with Arb. Brit, as an authority to each name, 

 and to include no name in the catalogue for which they have not a living plant. 



3. To label the plants as in nurseries and botanic gardens, either with 

 names or numbers printed on proper labels ; and, if numbers, to place the 

 same numbers before the names in the printed catalogue. 



4. To agree that no additional names shall be introduced into any sub- 

 sequent edition of the catalogue, so long as we live, without our sanction ; 

 or without applying for it, and waiting, for a period not longer than a fort- 

 night, for an answer. 



These conditions being agreed to in writing, we make offer, in all such 

 cases, to examine the living plants or dried specimens, state what we consider 

 to be their names, and prepare a proper catalogue, and superintend its print- 

 ing (provided the printing be done at Mr. Spottiswoode's press, as being the 

 most accurate in London for the spelling and accentuation of botanical names). 

 Once in the course of every year, in July, August, or September, such addi- 

 tional species and varieties as may be procured by the nurserymen who 

 accept this offer will be examined by us, and the names received with them 

 confirmed, or the proper ones given or ascertained. 



The same services, on the same conditions, are offered to nurserymen 

 and curators of botanic gardens or public collections, in every part of Great 

 Britain and Ireland, who will send us dried specimens, in general not less 

 than a foot or two in length, gathered during August or September, and 

 carefully packed, addressed to the care of Messrs. Longman and Co., carriage 

 paid. 



We do not bind ourselves to comply with these conditions after the 

 middle of October next, except as respecting the additions to the catalogues 

 of the nurserymen who may have adopted our names. We make this con- 

 dition, because, after the middle of October, the greater part of the leaves 

 will have dropped from the trees. 



We offer these services gratuitously to commercial men and public bodies : 

 but the possessors of private collections are too numerous for us to under- 

 take the task for them ; or, if we do so, it will be at our usual rate of a guinea 

 an hour, or five guineas a day of eight hours, which has been our professional 

 charge for the last thirty years, as indicated in detail in our Advertising Sheet 

 for January, 1839. 



We wish it particularly to be observed, that we will not undertake the 

 naming of public or commercial collections of any kind, unless the parties 

 will, immediately after our supplying the proper names, have labels of iron, 

 wood, or brick, with numbers or names, placed against the plants; and, if 

 numbers are preferred to names, then we require that the same numbers be 

 given along with the names in the catalogue to be printed, as a safeguard 

 to the public, as well as, in the case of nurserymen, to facilitate the ordering
