of the star observations. The deviation is not so great but that it 
may find its natural explanation through the mean error. As we 
are here only dealing with observations of the sun near its upper 
culmination, it was to be expected, according to the above, that the 
refraction computed and so also the latitude would appear to be 
too great. There is perhaps a tendency in that direction, in that the 
value found is 0”.7 larger than that found by means of the star 
observations. 
The mean value of the Besslian refraction corresponding to the 
ten first-named determinations of latitudes by means of the sun is
