remark, that the fall of the rivers opening in the Volga is 

 110 feet, those that are affluents to the Neva fall 445 feet, 

 making a total of 555 ; now, adding this total to the surface 

 of the Caspian, there appears to be only 200 feet remaining 

 for the culminating ground at the sources of the Volga; 

 but if these are estimated on measurement based in error, 

 and we make the elevation to be about 700 feet at the high- 

 lands of Vologda ; still taking the lowest level between the 

 Euxine and the Baltic to be in a line of latitude 58, the 

 waters of the two were of no dissimilar height, while the 

 Gulf of Bothnia was still an open strait, and the northern 

 portion of the Old Continent had not as yet commenced 

 rising. It appears that Norwegian Lapland has risen 1800 

 feet in the last 1200 years. 



At page 58, note, we should have added, that even the 

 byssus of the pinna was not destroyed. 



Page 76-78, the volcanic disturbances of the Red Sea 

 were again in operation in the last or in the present year 

 (1847) when a new island rose above the surface in the 

 southern portion. The French survey, for a canal between 

 Suez and Lake Mensaleh, recently published, likewise 

 countenances the opinion, that the isthmus was originally 

 open. 



Page 90. Among others, is the tale of Moshup, the giant 

 spirit, who resided at Nop, now Martha's Vineyard, at a 

 time when the currents ran differently, and ice used to pack 

 about Nantucket shoals. But better evidence is found in 

 the researches of Mr. Lyell, who considers the south-eastern 

 portion of the United States, about Savannah, to be sub- 

 siding, while Canada, and latterly Nova Scotia, are shown
