to understand why the intercalation of crystalline rocks, simulating 

 stratification, described by the Author, should be any proof of 

 dynamo-metamorphism. As regards raised beaches and sea-marks, 

 he entirely agreed with Col. Feilden. They abounded in the fjords 

 of the more southern part of Norway, and almost everywhere to 

 the north. As had been often described, their height above the 

 sea varied even in the same fjord, and they contained sometimes 

 marine shells. If they were due, in the north, to lakes dammed up 

 by ice, where was the ice-sheet formed, and how was it, if so great 

 a mass of ice existed, that the Norway valleys were not filled with 

 glaciers instead of water ? 



The Author, in reply, regretted that he had been unable to land 

 in Norway. The authenticated occurrence of marine organisms in 

 raised beaches would be conclusive ; but slight differences in their 

 levels might be misleading. He saw various moraines, but no well- 

 marked beaches along the main coast. He inferred dynamo-meta- 

 morphism from the interstratification of limestone with gneiss and 

 a granitoid rock, as in the district round Christiansund, where the 

 whole series had been folded together.
