NOTICE TO HEADERS. 



The Editors will be glad to receive tlie printed Reports of all 

 Scientific Societies (Metropolitan or Provincial), including those of 

 Schools and Classes of Science, and of Naturalists' Field Clubs. Also 

 Scientific Addresses, Reports, and Lectures. 



Manuscript sent for approval must be accompanied with sufficient 

 stamps to cover the return postage in case it should be deemed unsuit- 

 able. Observers in all branches of Science are invited to communi- 

 cate briefly their new observations, but copies of these must be kept 

 by Authors, as they cannot be returned if not considered suitable 

 to the pages of this Journal. 



Contributors are alone responsible for their opinions on Scientific 

 subjects. The desire to publish both sides of a debated theory may 

 often necessitate the insertion of views at variance with those of the 

 Editors. 



No notice whatever will be taken of anonymous communications.
