Editorial. 



TnK i)iiblication of the observations and discoveries of those, who 

 form the staff of a well -organized museum, has always been recognized 

 as a proper function of such an institution. The body of scientific 

 literature, which has emanated from the larger museums of Europe and 

 America, is very considerable, and comprises some of the most im- 

 l)ortant and valuable contributions, which have been made to science. 

 Though the Carnegie Museum is the youngest of the great museums 

 of America, and may be said only quite recently to have embarked 

 u])on its career of usefulness, the labors of those connected with it 

 have already resulted in the accumulation of a large amount of material, 

 possessing great scientific interest and value. The study of these col- 

 lections is certain to throw much light upon many questions of |)ro- 

 found interest. For the purpose of facilitating the diffusion of 

 knowledge gained, often laboriously and at great expense, by those 

 who are directly connected with the museum, as well as to form a 

 medium for the publication of the results of the labors of others, who 

 are a.ssociated with them, or are pursuing inquiries along the same, or 

 kindred lines, the Trustees of the Institute have authorized the pub- 

 lication of two series of papers, which will be designated respectively 

 as AxN.M.s and Memoirs. The Annals will appear in octavo form, 

 the Memoirs in cpiarto. They will be published from time to time as 

 material is provided, and when pages enough to form a volume have
