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



B. Observations with the Sextant. 



Observer: Lieutenant Scott-Hansen, when not otherwise stated. 



The date is astronomical and the hours are counted from the same noon as in list A, 

 except for the meridian-altitudes of the Sun, where "Noon" or "Midnight" are local, in which 

 case the date of local noon, when different from that of the clock, is enclosed in hrackets. 



U. L. and L. L. signify upper and lower limb. 



The column "Hor." either gives the height of the eye (in metres) when the natural horizon 

 was used, or indicates the kind of artificial horizon (mercury, glass, tar, water) when double 

 altitudes were measured. In the case of a glass-horizon the level reading is added in the 

 column of Remarks. 



The index error was only rarely determined in the beginning (1893, August and September, 

 1894, February 18, April 17 and July 23) but after 1895, February 5, very frequently. 



The comparisons between the chronometer Hohwti and the observer's watch are either 

 taken from the journal of observations, when there noted, or from the journal of daily comparisons. 



What is here called a mile is, in the original, after the custom of our sailors, called a 

 quarter mile, and means 1' of great circle.
