I.— TO THE EEADERS of the GEOLOGICAL MAGAZINE. 



IT may interest our readers if we remind them that with the 

 publication of our July N^umber the Geological Magazine 

 enters upon the fiftieth year of its existence. The first number 

 was issued in July, 1864, and the first volume consisted of six 

 numbers for the half-year.^ Consequently the commencement of the 

 fiftieth velume took place in January of the present year. It must 

 be a matter for congratulation to the Editor that during so extended 

 a period he has personally edited every number, excepting three, 

 when he took a long vacation in Italy and could not conveniently 

 deal with proofs. Such a i-ecord is probably unique. It is moreover 

 satisfactory to learn that there has at no time been a serious lack of 

 useful material wherewith to fill the pages of the Magazine. In our 

 copy of Yol. I there are lists of Local and Foreign Correspondents ; 

 among the former is the name of the Rev. H. H. Winwood, and 

 among the latter are the names of Baron Adolph von Koenen and 

 Dr. Anton Fritsch. Amongst surviving contributors to the 1864 

 volume may be recorded the Rev. Osmond Fisher, Sir A.rchibald 

 Geikie, Professor Edward Hull, Sir E. Ray Lankester, and Henry 

 Woodward.

Introductory Remarks. 



SOME years since Professor E. J. Garwood sent to me for examination 

 some pieces of limestone from the Lower Carboniferous rocks in 

 the Shap and Ravenstonedale districts of Westmorland, in which he 

 had observed the rounded outlines of fossils with a structure which 

 appeared to him to resemble that of Stromatopora. The rock in 

 which the fossils were embedded was so compact and hard that they 

 could not be extracted, and it was necessary to make sections in 

 various directions in order to ascertain their structure, which proved 

 to be identical with that of Solenopora, now well known as one of the 



' But the completicm of the actual fifty years (or Jubilee of the Geological 

 Magazine) will not be reached until June, 1914. — Ed.
