LIFE OF JAMES DWIGHT DANA 



" Now that you have a full report of your lectures on 

 Genesis, I hope it may not be long before they are in 

 print. I desire greatly to see your thoughts so pro- 

 found, so full of good for man in these days of increasing 

 scepticism circulating widely. 



" I met Hall at Poughkeepsie last fall, and the subject 

 of a geological map came up, as we had corresponded at 

 several different times on the subject, and I mentioned 

 reasons why he should publish one at once, but not be- 

 lieving anything would come of it. ... 



" I received a letter from Lesquereux about the Ohio

 mendation as the man for the survey ; and I hope he may 

 not be disappointed with regard to it.

 for the normal condition. I feel anxious to work, and

 augmenting realization of the greatness and extent of the 

 work to be done to keep science headed aright in these 

 times. There is wonderful comfort and strength in the 

 thought that God is with the right, and will give triumph 

 to the truth."

' Your kind note was very welcome. With regard to 

 the Quarternary you saw deeper than I did when the first 

 edition of the Geology was in preparation. As to the 

 ' Age of Invertebrates,' I had forgotten that you fa- 

 vored the term. Not long after the Manual was pub- 

 lished, I had a letter from Murchison telling me that he 

 had proposed the term, Age of Invertebrates, and arguing 

 for its adoption, and I have ever since been in favor of it. 



' With regard to species, I am off a little from my old 

 ground and yours. But the more I have thought of late 

 over the first chapter of Genesis, the more ready I have
