NATURALISTS' DIRECTORY 



It is proposed to issue several pages of this Appendix with each num- 

 ber of the Proceedings, in order to allow naturalists an early opportunity of 

 stating their wants and what specimens they have for sale or exchange ; to 

 give notices of proposed works on Natural History ; changes of address of 

 persons whose names have appeared in the Directory ; short obituary no- 

 tices ; new names for the Directory ; and such other matters as may be of 

 interest and appropriate to the work. 



Notices of the change of address or the decease of any person whose 

 name has appeared in the Directory are especially requested, and any person 

 knowing Naturalists whose names have been omitted, will confer a favor 

 by .sending the addresses of such to the editor. 



Five lines in the " Appendix " are allowed to each subscriber to the Pro- 

 ceedings for notices of specimens and articles for sale. When a notice of 

 more than five lines is inserted 10 cents per line will be charged for every ad- 

 ditional line. Non subscribers will be charged 10 cents per line for any ad- 

 vertisement of specimens for sale. 



All notices from subscribers or others, except of specimens or articles 

 for sale, inserted free, at the discretion of the editor.
