LIFE OF JAMES DWIGHT DANA 



DANA TO GEIKIE 



" NEW HAVEN, July 19, 1882. 



" The copy of your Geological Sketches which you 

 kindly addressed to me has been received, and I thank 

 you much for it. I have already told you of my delight 

 in reading some of the sketches, and they are all excel- 

 lent. . . . 



" I am greatly interested in the discovery of fossils in 

 the metamorphic rocks of Bergen, Norway, announced in 

 a recent paper by Hans H. Reusch. The rocks (Upper 

 Silurian) are much like those west of our New Haven.'*

" I have also to thank you for your paper on Coral 

 Islands. I still believe, however, Darwin to be right 

 probably, and, as I have seen and studied many of the 

 islands as well as coral reefs, I may state the Darwin side 

 of the subject before long in our Journal of Science."

" I thank you for your note of the 6th, received three 

 days since, and am not much surprised that your Scotch 

 facts should come forward for an explanation of Taconic 

 geology. I was greatly interested in your paper, and on 

 receiving a copy of it (from you, I think), I inserted it 

 in our Journal (vol. xxix., p. 10, 1885) entire. It brought 

 before me the possibilities, and I at once reviewed the 

 Taconic subject with reference to them. The conclusion 

 was that we have not in Berkshire, or the Taconic region, 

 a single one of the conditions you find in Scotland, and 

 which have so long been a vexation to British geologists. 

 We have in no case a more crystalline structure or 

 mass overlying a less crystalline; but a perfect corre- 

 spondence between the limestone and adjoining schist in 

 grade of metamorphism. Where the Canaan fossils occur 

 the adjoining slate looks very much like your Welsh
