The NATURALIST. 



X:o< 



It being the wish of the Editors to make the journal the recognised organ for 

 information concerning the natural history of the North of England, they hope 

 to rely on Naturalists keeping them supplied with articles and short notes 

 from time to time. 



Communications should be written on one side of the paper only, and 

 should be sent as soon after the commencement of the month as possible. 



Short Notes of important occurrences will be received up to the 20th of 

 the month, and specially urgent ones even later.

 of papers exceeding 3 pages. Reprints may be had at the following rates, if the

 16 pp. 9/-; 100 copies, 4 pp. 6/6 ; 8 pp. 8/- ; 12 pp. 10/6 ; 16 pp. 13/-. Covers extra. 



Subscription 5/- per annum, post free. Single numbers, 7d. each, post free.
