Og Lyell forlælier selv videre om sin stilling til spørsmaalel 

 om landets stigning paa den skandinaviske halvø: »In former 

 editions I expressed many doubls as to the validity of the proofs 

 of a gradual rise of land in Sweden. A detailed statement of 

 the observations which I made in 1834, and which led me lo 

 change my opinion, will be found in the Philosophical Trans- 

 actions for 1835, part I' (Lyell: Principles of Geology, 4th 

 edition, Vol. II, 1835, pag. 337). Jeg har allerede ved en tidligere 

 anledning (Norsk geol. tidsskrift, B. II, Nr. 7, pag. 6) gjort oj)- 

 merksom paa de betydningsfulde iagttagelser, som omtrent paa 

 denne lid blev gjort af James Smith of Johdanhill. Og i sin 

 »Address delivered of the Anniversary Meeting of the Geologicai 

 Society of London 18y37« yttrede Charles Lyelf. følgende: 

 'Changes in the relative level of land and water, in the estuary 

 of the Clyde, are indicated by fads described in anolher paper 

 by Mr. Smith of Jordan Hill, near Glasgow. Superficial de[)Osits, 

 in which a great number of marine shells of recent species are 

 imbedded, are found on the banks of the Clyde below Gla.sgow, 

 at the heighl of 3() or 40 feel above the sea. I had myself an 

 opporlunily of verifying during the last summer several of these 

 observations of Mr. Smith, and found e(|iially clear proofs that
