the name of Kase Gauen Ajeli (nose valley spring). Its temperature, 

 on the 2<>d of July, was 3 "i-1 6°. 



A third spring, Valetjocks-k'dlla, lies directly above G'dtingen- 

 kalla, on the north side of the little hill Valletjock. Its tempera- 

 ture, on the 22d of July, was 33-S°. 



The Laplanders are well acquainted with all the springs in these 

 parts. They supply them with water when all the rivulets and 

 rivers are covered with ice. There is likewise a spring on the 

 south side of the ridge, called Praestcn Middags Kiilla, about a 

 Swedish mile south-west from the preceding, and a quarter of a 

 mile north from Ammor Tr'dsk, Its temperature, on the 22d of 

 July, was likewise 33*8°. Andromeda Injpnoides was the only plant 

 which covered the ridge of the mountain. 



Near the snow line we can hardly expect any other temperature 

 of the earth than the freezing point; for supposing the temperature 

 of the air to be higher, how could it counterbalance the perpetual 

 oozing of the melted snow ? especially as it is the water which 

 spreads and equalizes the temperature of the earth.

Observations on the Heat of Springs in the Southern Provinces of 

 Sweden. By George Wahlenberg. 



I have continued my observations on the heat of springs at 

 Upsala, chiefly because I was of opinion that the temperature of 

 inconstant springs might give the difference between the mean 

 temperature of different years and seasons. Nor have my hopes 

 been entirely disappointed, as the following observations will show:
