17 AN EPISCOPAL TRILOGY 159 



Professor Archibald Geikie, who in a special dis- 

 course and in several treatises on geology and 

 physical geology very strongly supported the new 

 theory. It would be an endless task to attempt 

 to give references to the various scientific journals 

 which have discussed the subject, but I may add 

 that every treatise on geology which has been 

 published, since Mr. Murray's views were made 

 known, has dealt with his observations at con- 

 siderable length. This is true of Professor A. H. 

 Green's "Physical Geology," published in 1882; 

 of Professor Prestwich's " Geology, Chemical and 

 Physical " ; and of Professor James Geikie's " Out- 

 lines of Geology," published in 1886. Similar 

 prominence is given to the subject in De Lap- 

 parent's " Traite de Geologie," published in 1885, 

 and in Credner's " Elemente der Geologie," which 

 has appeared during the present year. If this be 

 a " conspiracy of silence," where, alas ! can the 

 geological speculator seek for fame ? Yours very 

 truly, JOHN W. JUDD. 



October 10, 1887.
