THE XA rURALlSTS' DIRECTOR]', 



ii FOR TLA XD S TREE T. 



Boston, Mass., Jan. io, 1895. 

 Dear Sir: — 



We are now preparing the new edition of The Nat- 

 urahsts' Directory, an J have decided to add to its value and useful- 

 ness, by arranging it in three ways. ist, all names will be arranged 

 alphabetically as in previous editions; 2d, names will be arranged 

 alphabetically under the names of towns and cities in each State; 3d, 

 an arrangement of all names under Departments of Science. 



As the work may not be issued again in this form for a long 

 time, if ever, all who desire to subscribe should do so at once, as 

 the edition will be printed from type and will be limited. 



No discount will be allowed booksellers as we prefer to deal 

 directly with our subscribers, and you should therefore return accom- 

 panying blank at once. 



As most Naturalists are interested, in a general way, in many 

 branches, it is desirable that each person select and indicate on the 

 blank sent herewith ONLY THOSE IN WHICH HE IS ESPEC- 

 IALLY INTERESTED, in order to economize in the matter of 

 space as much as possible. 



In filling out the blank on reverse, please condense the address 

 as much as is consistent with accuracy. As professional Naturalist's 

 will be indicated in the Directory, it will not be necessary to give 

 long titles. 



The work will be issued about March i, 1895. 

 Yours respectfully, 



S. E. CASSINO, Publisher
