PHILIP DOWELL, PORT RICHMOND, N. Y. 



THE SULLIVANT MOSS Society cordially invites all persons 

 interested in the study of Mosses, Hepatics and Lichens to become members. 

 Membership fee $1.50 per year including subscription to the Bryologist. 



The Society was founded over fourteen years ago to help and encourage 

 the study of those plants and the Bryologist was started as an aid to beginners. 

 As time has gone on books adapted for beginners have been furnished by the 

 present editor; the Bryologist itself has become more and more an organ for 

 the publication of purely scientific articles. But remember the Society it- 

 self IS still active in its work of helping beginners and it has the assist- 

 ance of the leading students in this country and in Europe and the back numbers 

 of the Bryologist are still available. 



The ofhcers of the Society and especially the curators stand ready to name 

 any specimen sent them, if it gives evidence that the person sending is in earn- 

 est and trying to help himself. More short pithy notes of individual finds and 

 observations are invited and will be published if presented and a valuable her- 

 barium can be obtained through the Exchange Dep't. Join us and see.
