regarded as being in the nature of public trusts, and should be accessible 

 to all duly qualified students, under only such reasonable restrictions as 

 are necessary for their protection or as is consistent with the owner's work. 



Finally, it is urged that provision be made so that specimens taken will 

 ultimately find their way into permanent or public collections where they 

 will be available for study by future generations and not be wasted and lost 

 through neglect. 



While all these conditions are not strictly mandatory, and their spirit 

 will be liberally interpreted, they will be considered in the granting or 

 renewal of each permit, and evidence of gross violation of them may be 

 deemed sufficient ground for the refusal of an application or for the revoca- 

 tion of any permit already granted. 



It is hoped and expected that the justice of these principles will be realized 

 and that collectors will co-operate in advancing science to the utmost 

 without unnecessary waste of valuable bird life.

Capt. Thomas Brown's ' Illustrations of the American Ornithology 

 of Wilson and Bonaparte.' 



Editor of 'The Auk': 



In 'The Auk' for April, 1903, pp. 236-241, I gave an account of Capt. 

 Thomas Brown's Edinburgh reproductions of the plates of Wilson and 

 Bonaparte's 'American Ornithology.' I showed that Brown's scheme 

 involved three independent reproductions of the American plates, one on 

 copper in folio, one on copper in royal octavo, and one on stone in 16 mo. 

 The three books that resulted from Brown's endeavor are among the 

 rarest in ornithological literature and therefore of great interest to bib- 

 liographers. 



In 1903 I was able to place only three copies (one imperfect) of the folio 

 edition and one of the 16 mo. edition, the latter consisting of nineteen 

 plates bound in a copy of Jameson's 1831 edition of Wilson and Bonaparte 

 in your own library, Mr. Editor. Many years ago Professor Alfred Newton 

 supplied Dr. Coues with a description of Part I of this miniature edition, 

 and its title-page is quoted in Coues's Bibliography, ' Birds of the Colorado 

 Valley,' p. 600; but when I saw Professor Newton in June, 1902, he had 

 lost all recollection of it and we together searched his library for it in vain. 



Of the existence of the royal-octavo edition I was unable to find a trace. 

 I surmised, however, from the way the plates of Jardine's 1832 Wilson and 

 Bonaparte were unmercifully trimmed to match the size of the text, that 

 this edition was soon appropriated by Jardine to illustrate his own work.
