108 GEELMUYDEN. ASTRONOMICAL OBSERVATIONS.  [NORW. POL. EXP. NO. 6.] 
|. Refraction. 
The following list contains the observed altitudes of low stars or of the Sun’s limb, and 
the true altitudes of the same objects as computed from the given latitude and clock correction, 
the difference being either the refraction, or, in some cases indicated by an asterisk, refraction + 
dip of the horizon. For these the height of the eye is given among the observations. It should 
be remarked that in the case of the Sun, the latitude and clock error was generally not immediately 
given for the time of observation, but has been interpolated. 
1894, April 27, the refraction seemed variable during the observation. 
1894, October 15, the Sun’s lower limb was seen with the naked eye to touch the apparent 
horizon shortly after noon. Limb boiling, trembling horizontal stripes across the disc, upper 1/4 
hidden in clouds. 
1895, March 10, the altitude of the apparent horizon, measured with the altazimuth, was 
+ 0° 13'.
