Fjord, formerly visited by Rink and also by Steenstrcp (MedcL 

 от Grønland, Hefte 24 p. 299). It rises vertically through 

 several mouths, situated at the top of a slight elevation of the 

 ground. At the time of my visit, ^Vviii 1902, the temperature 

 varied in the different mouths from 11.33° to 11.65°. Rink 

 found in June 1849 12.5°, and Steenstrcp on the Vix 1898 in 

 the three hottest points 12°, 11.3° and 9° respectively, while 

 on the following day, after some rain and snow, the highest 

 temperature recorded was only 7° M- The water issues forth through 

 fine sand, and in several places 1 observed bubbles of air, 

 amounting I think to about 100 cc. each time, coming out of 

 the sand at regular and very short intervals (about every 1 5 

 seconds). From two points these bubbles were collected and 

 analysed, and in addition the CO^-tension of the water was 

 determined in the ordinary way. 



The air-analyses showed for the carbonic acid and 

 and for the oxygen 14.47 and 13.64% respectively, in two 

 samples of the Avater a tension was found of 2 and 2.5 respec- 

 tively. I explain the results in the following manner. 



From very deep strata a stream of water finds its way 

 through the covering sheet of frozen rock and ice. I suppose 

 that this rising must take place with considerable velocity 

 through a narrow fissure or channel, as the spring comes up 

 artesian-like through the loose earth above the ice, and because 

 the temperature, sometimes at least, may be remarkably high. 

 A portion of the water must, however, be stopped by the loose 

 earth and attempt to flow along the surface of the ice in the 

 ground; but thereby the ice will be melted and a sort of wide 

 funnel, as shown in the diagrammatic figure 9, will be formed. 



'*) GiESECKE (Mineralogische Reise in Grönland, Copenhagen 1878, p. 25) 

 mentions an Unartoli in Southern Greenland with a temperature of 40°. 

 During his stay it began to rain, and in a quarter of an hour the 

 temperature fell to 30°. The temperature of the hot springs in Green- 

 land alwavs seems to be lowered bv rain-fall.
