LETTERS TO A. GEIKIE 



in this country, leading geologists generally to misunder- 

 stand the Sedgwick-Murchison relations and condemn 

 the Geological Society for its course. In view of it, and 

 the general ignorance on the subject, I have been led to 

 prepare a simple historical account of the labors of the 

 two geologists, year by year, up to the time of Sedg- 

 wick's paper of 1854. The article will appear in the 

 March number of the American Journal. I wish that it 

 might have had your revision, but hope that it contains 

 no important errors. I have endeavored to do full justice 

 to both of the eminent geologists. I send you a copy in 

 advance of publication. My desire will be fully accom- 

 plished if it put right ideas into our American geologists. 

 But if it can be in your opinion of any service in England, 

 I have no objection to its republication at the time of 

 its appearance here you making any emendations in it 

 which may be needed. . . ." 



DANA TO GEIKIE 



" NEW HAVEN, April 18, 1890. 



" I have just sent to the post, addressed to the Geo- 

 logical Society, a copy of each of my new works just pub- 

 lished, the volcano book and the new edition of my 

 Coral and Coral Islands. In the latter you will find a 

 strong argument for Darwin in the map of the Louisiade 

 Archipelago, and some new facts from other sources. I 

 have a map of the region of Honolulu (Oahu) in the 

 Appendix showing the positions of the artesian bor- 

 ings. . . ." 



Among the younger correspondents of Professor Dana 

 in his later life, he valued highly Professor John W. 

 Judd, Professor of Geology in the Royal School of 

 Mines, for eight years Secretary of the Geological So- 

 ciety of London, and subsequently its President. Three 

 of the letters addressed to him by Professor Dana are 

 here given, all written toward the close of Dana's life.
