During the period of years covered by these dates we have 

 direct statements of the occurrence of some irregularities. We 

 can only mention some few instances. We see, for instance, 

 that „de 1876 à 1883, deux courants des Oxtinder auraient pro- 

 gressé," and „de 1879 à 1882, une branche du Frostis aurait 

 avancé." Further on, the Glacier of Fonddal, about 1880, is stated 

 to have undergone „une progression momentanée". And, in the 

 year of 1897, a glacier on the northern side of Jækkevarre was 

 stated to have passed through „une récente progression partielle 

 de la glace." 



Having now made some excursions round our scattered, 

 more or less extensive glacier regions, situated as they are along 

 our western coast, or near to it, we will once more enter the 

 interior of our country, in order to take a last look at the oscil- 

 lation of glaciers in the region of our High Mountains, Jotun- 

 heimen, a name given, according to information kindly forwarded 

 to me by Professor Helland, by our popular poet, Vinje. This 

 name, however, is only to be regarded as a more national version 

 of Jotunfj eldene, the name used for several previous decades of 

 years. 



As already stated, a general decrease of glaciers seems to 

 have prevailed in this region during the latter half oï the nine- 

 teenth century. As the knowledge of these mountains in course 

 of time has grown more complete, and as the numerous snow- 

 fields covering the mountain wilds, and the glaciers filHng up 

 the cirques and the high valleys, have been more thoroughly 

 explored, the statements regarding this decrease have, at the 

 same time, become more numerous, and have acquired a more 

 precise character. At the same time, however, some few state- 

 ments have also been met with, indicating some slight aberra- 

 tion in the oscillation of glaciers during the decades of years 

 towards the end of the century. 



An overflow, for instance, of the Glacier-Lake of Upper 

 Mjölkedal is stated to have occurred in the year 1878 or 1879.
