Level of the Dead Sea. — " On the 12th of March, 1865, the 

 party reached the Dead Sea, when its level was found to be 1,292 

 feet below the level of the MediteiTanean ; but it was ascertained 

 that at some time of the year, probably after the winter freshets, the 

 water rises 2i^ feet higher, which would make the least depression 

 1289-5."— Sir H. James, Proc Boy. Soc, May, 1866. 



Geological Map op Southern Norway. 

 By Theodor Kjeritlf and Tellep Dahll. Cliristiania, 1866. 



The Geological Survey of Norway was instituted in 1858 by order 

 of the Eoyal Government, and this map, comprising the whole of the 

 coimtry to the south of the Dovrefield and Langfield Momitains, is 

 the result of the work done from that time to 1865, by the authors 

 and fifteen assistants, who were engaged during the summer months. 



The map is a very neat production, the colours being clear and 

 distinct ; it is rather to be regretted that none of the physical features, 

 with the exception of rivers and lakes, are delineated on it, but this 

 omission is in some measure supplied by a number of horizontal sec- 

 tions (uncoloured). 



The greater part of the country is composed of granitic and the 

 older Palceozoic rocks, which in the mountainous regions are much 

 disturbed, the granites being of an eruptive character, dislocating 

 and upheaving the sedimentary rocks. 



The following is a table of the strata exposed in Norway, as deter- 

 mined by the Survey, and coloured on their map : —
