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



1H96, June 7. Bar. 746.9 ram, Temp. - 2.4 C. 



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

Snow island, southern point S 58 W 



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 <f = 80 39'; the diffe- 

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

 intersection gives also A = 8 m 10 3 , or watch I I 11 l m 56 s in advance of M. T. at the Winter Hut; 

 on May 16 the error was O 11 57 m 24 s , consequently an acceleration of 4 m 32 s 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 

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

 moraine island" (J. Koettlits 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 Keltic 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 I 11 13 m , corresponding to 

 A = 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 

 \vrst 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.
