THE 



GEOLOGICAL MAGAZINE. 



TO OUR GEOLOGICAL FRIENDS AND THE SCIENTIFIC PUBLIC. 



Three years and a half have passed since the Geological 

 Magazine took the field, and during that period it has justly- 

 earned for itself the good- will and support of all those most warmly 

 interested in the pi'ogress of Geological Science, and has proved 

 the readiest and most frequent medium of intercommunication for 

 English and Foreign Geologists, its pages being always " open to 

 all comers." 



It commends itself strongly to Students and working Geologists, 

 whose inquiries will be answered direct, or inserted in the pages of 

 the Geological Magazine, in the form of " Notes and Queries," for 

 which space will always be provided. 



Our numerous correspondents are earnestly requested to make 

 their letters as concise as possible, so as to admit of the insertion 

 of as much and varied information as the space at our disposal will 

 admit. 



Our best thanks are due to our Geological friends, not only for 

 their support, but also for their contributions of valuable original 

 articles, of which we have had no lack. 



We would remind our friends generally that the mere reading of 

 the Geological Magazine, although a very good and commendable 

 thing in itself, is not all we expect from them. Like the Poet 

 Close, we earnestly hope that each and every able-bodied Geologist 

 will " buy a copy of our little work " for themselves. 



Annual Subscribers should send in their names and subscriptions 

 to Messrs. TRiiBNEH & Co., 60, Paternoster Eow, London, E.G. 



The Geological Magazine can always be obtained through all 

 Booksellers in town or country ; but if any difficulty or delay arises 

 through this method of procuring it the Publishers will always be 

 happy to send it direct per post. 



The Editor.
