Bessey, C. E., A Suggestion in regard to the publication of new 

 species. (The Amer. Naturalist. XVIII. 1884. p. 71.) [„Somemonthsagooneof 

 the foreniost of our American botanists stiggested the propriety of demanding in 

 case of publication of descriptions of new species in scientific Journals , that 

 specimens should in every case accompany the descriptions. The Suggestion 

 is tcell worth considering in these days when nearly every discoverer is 

 inclined to make free use of his right to describe tvhat he has found. There 

 can be little doubt that it is wise to permit and encourage such ivork on the 

 jyart of our best collectors. The Stimulation it gives to the whole work in 

 the field of Systematik botany is no small part of the good which results. 

 But a serious inconvenience often arises as a conseqtience of such a mode of 

 publication. It is , in the first place , difficult to find the descriptions on 

 account of the well-known inaccuracy of most of the Journal indexes, and in 

 the second place it too oftens happens that the specimen upon which the 

 descriptions were based, soon become inaccessible. These difficulties might be 

 more or less completely remedied by our scientific Journals adopting a:iy of 

 the following plans : 



1. Every description to be accompanied by the Statement that type specimens 

 were deposited in this or that established herbarium. 



2. Every description to be accompanied by specimens to be distributed 

 by the editor of the Journal giving such publication. 



3. No description to be given until specimens are deposited in the National 

 Herbarium. 



The last is essentielly the recommandation made in the November number 

 of the London Journal of Botany. It would simplify matters very much if 

 in every case the deposited specimens were soon aceompanied by the printed 

 descriptions. We shall return to this matter again ere long , and in the 

 meantime shall be glad to receive further suggestions."]
