PROSPECTUS. 



For some time past there has been a desire for a medium through which students 

 of Natural History and the kindred sciences at the Nation's Capital could communi- 

 cate with each other the results of current observation in the field and laboratory, and, 

 at the same time, place on record notes of any new facts of general interest to the sci- 

 entific world that might come under their notice. 



To meet this want, Field and Forest has been projected, and, under the patron- 

 age of the Potomac-side Naturalists' Club — a natural history society founded several 

 years ago — it starts out with a corps of Contributors composed mainly of gentlemen of 

 recognized authority in the various branches of science, many of whom are eminent in 

 their specialties. 



A monthly record of the proceedings of the Naturalists' Club will be given, and ab- 

 stracts of papers read before the clul") will be published when upon subjects of special 



interest.
