especially the fact that even in cases of fixed dates, the ampli- 

 tude of oscillation is generally unknown. The curves represent 

 the oscillation of these glaciers in the following order: No. I, 

 the Glacier of Buer, No. II, the Glacier of Bondhus, No. Ill, the 

 Glacier of Boium, No. IV, the Glacier of Briksdal. 



There is another of the branches emanating from the exten- 

 sive snow-field of the Jostedalsbræ, that deserves special atten- 

 tion, viz. the Glacier of Nigard. We have already followed the 

 oscillation of that glacier down to the year 1851. Subsequently 

 we find some scanty statements as to the oscillation, of that 

 glacier. It was stated, for instance, to be decreasing in 1864, and 

 De Seue writes : „II parait que le glacier a déjà été en voie de 

 progression en 1868. Auparavant on dit qu'il était en retraite." 

 In the year 1899, one of the peasants of Nigard pointed out a 

 terminal moraine, then 500 metres in front of the glacier, said to 

 have been thrown up by the glacier 25 year's ago. On the same 

 occasion, the distance between the moraine of 1748 and the lower 

 end of the glacier in the summer of 1899, was stated to be 2100 

 metres (1. c. pp. 5, 9). According to these statements, the dis- 

 tance between the moraine of 1748 and the lower end of the 

 glacier, in the year 1874 was about 1600 metres. In the summer 

 of 1878, however, Holmström stated the distance between that 

 moraine and the lower end of the glacier to be 1000 metres. In 

 the summer of 1899 this glacier was decreasing. In the present 

 year, 1900, however, the position of the glaciers of the Valley 

 of Jostedalen was stationary, according to statements forwarded 

 to me by Lars Lien, a guide in the Jostedal. 



In order to get a general view of the oscillation of the Gla- 

 cier of Nigard, we must tabulate dates, amplitude, phase of oscil- 

 lation and names of the respective observers as far as our know- 

 ledge will allow. The scarcity of accounts is very noticeable. In 

 the first column of the table we place the dates of observation, 

 and in the second the distance, in metres, between the lower end 

 of the glacier and the moraine of 1748. In the third column of
