ocean, and on the other side by that of the lofty moun- 

 tain masses and chains of mountains, which follow the 

 general direction of the shore. 



The central point of the lowest mean annual tempera- 

 ture in the peninsula of Scandinavia is at a point inter- 

 mediate between the Varanger fiord and the Gulf of 

 Bothnia. There, as in Finnish Lapland, the mean annual 

 temperature is as low as 3 = 26 '6 Fahr. 



The yearly isotherm of 2 = 28'4 Fahr., include in 

 Norway the south part of the parishes of Kautokeino and 

 of Karasjok, in the interior of Finmark. Farther to the 

 south, the miners' village of Roros and its vicinity has 

 also that mean temperature. 



The isotherm of = 32 Fahr., passes to the north of 

 the Bay of Varanger, embracing the whole of Varanger, 

 and the whole interior of the prefecture of Finmark ; 

 thence it curves towards the south-west, following gener- 

 ally the chain of the Kjoelen to the prefecture of North 

 Drontheim, comprising of the prefecture of Tromso only 

 the most elevated mountain parts situated towards the 

 Lake Altevard. From the boundary of Nordland and 

 North Drontheim it bends to the east, enters Sweden, and 

 finally directs itself by a slight turning towards the bottom 

 of the Gulf of Bothnia, whence it goes on to the east in 

 Russian Finland. Further to the south, the isotherm of 

 = 32 Fahr., circumscribes in Southern Norway an oval 

 space, comprising the south-east portion of the prefecture 

 of Sondre-Drontheim, the north part of the valley of 

 Osterdal, so far as the northern extremity of the Lake 

 Stromsjoe, in the valley of Rendal, arid lastly, towards the 

 west, the Alpine region of Rundane. 



Nearly 18 per cent, of the whole area of Norway has 

 a mean annual temperature not exceeding 0, or 32 Fahr., 

 the freezing point of water. 



While the isotherm of C., or 32 Fahr., encloses thus 

 two separate portions of the country, the isotherm of + 2 

 C., say 36 Fahr., forms a single continuous line. It takes 

 its rise to the north of the North Cape, and proceeds
