ESMARK : MOLLUSCA OF NORWAY. 93 



where the small places Langesund, Brevik, Statelle, Porsgrund, 

 and Skien are situated, would certainly continue to reward a 

 zealous investigator. The whole south-western country to 

 Christiansand has only had a few day's examination, which 

 were of great interest. In Bergen and its neighbourhood, H. 

 Friele has now and then found something, but I do not believe 

 that these places have been more particularly examined. In the 

 diocese of Throndhjem nothing has as yet been done ; and 

 what has hitherto been collected on the whole long coast line of 

 Nordland and Finmarken, is so little, and in so few places, that 

 we may safely sa}^, as a whole, only a good beginning has been 

 made. 



The peculiar form of Norway from 58° to 71° 25" north lat. 

 gives a very long coast line, which besides in many places is cut 

 through with a very great number of small and large fjords, in 

 most cases excelling more through their length than breath. 

 They are in many parts surrounded by high mountains, particu- 

 larly in the dioceses of Bergen, Nordland, and Tromsd Amt. 



It must consequently seem to be a matter of course, that 

 the temperature must differ very much in Norway, and that the 

 higher you go towards the north the colder the climate must be, 

 as we thus more and more approach the coasts of the arctic 

 seas, and even reach them. How is it then jDossible to fancy 

 anything but ice and snow in these parts ? It is, however, not 

 at all the case. On the contrary, the temperature differs very 

 much from this supposition. As it might therefore be of in- 

 terest to many of the readers who have no opportunity to study 

 the meteorological relations of our country through annals or 

 experience, I have copied down a table from those edited by 

 the Metereologiske Institut in Christiania. The places have 

 been chosen (i) according to their different degrees of latitude, 

 (2) as lying inland or more near the coast, (3) according to the 

 altitude of the places.
