GEELMUYDEN. ASTRONOMICAL OBSERVATIONS. [NORW. POL. EXP. 



1896, June 7. Bar. 746.9 mm, Temp. - 2.4 C. 



Circle Hor. Point 89 53' + x, assumed latitude 80 40'. 



Compass 



Snow island, southern point S58W 



northern point N 76 W 



The cape we left yesterday (Cape Richthofen) N 6 E 



The last bearing may serve to correct the assumed latitude. Applying the magnetic 

 declination 17 E its intersection with the line of equal altitudes gives y = 80 39'; the diffe- 

 rential quotients then give the clock correction lh 10 m 23 s + 17s = lh IQm 6s. The same 

 intersection gives also * = 801 10*, or watch I 1^ 1m 56s i n advance of M. T. at the Winter Hut; 

 on May 16 the error was Oh 57 m 24 s , consequently an acceleration of 4m 32 8 in 21.8 days or 

 12.5 daily. 



After a good sailing on the ice from 7 p.m June 7, the travellers stopped at 7 a.m June 8 

 in a snow storm without reaching the land on the other side of the fjord (Jackson's Allen 

 Young Sound). A sketch from the following day has the bearing from west point of "low 

 moraine island" (J. Koettlitz Island) to west point of "low moraine land" (J. Hooker Island) as 

 S 10 E by compass. The stopping place of June 8 in the morning was about midway, but 

 somewhat to the east of this line. The west point of Koettlitz Island was more westerly than the 

 tent-place of June 67 on the north side of the island. On the same sketch is indicated a 

 small island about 6 miles west of "low moraine land", and another close to the north of it; 

 probably Jackson's Eaton Island and Scott Keltie Island. 



About 3 hours after leaving this station on the ice the following observation was taken: 



1896, June 9. Bar. 747 mm, Temp. ca. 0. Ind. corr. (+ 5'?), height of eye 4 feet. 



"Land about 2 miles off." 



The latitude is calculated with the assumed clock correction l h 13 m , corresponding to 

 * = 2,7, when the same acceleration is applied as before. 



The sailing on the ice continued till 6 p.m. Before stopping in the neighbourhood of the 

 west point of Hooker Island the travellers had to make a long circuit westwards, the ice be- 

 ginning to give way under the sledges. After stopping, the following observations were taken: 



Bar. 749.5 mm, Temp. + 1 .0 C. Ind. corr. (+ 5 ?), height of eye 7 feet.
