1895, August 28. At the place that was chosen for winter quarters. 

 Bar. 742.7 mm, Temp. - 1.0 C, Ind. corr. + 6'. 



1895, August 30. Same place. Bar. 742 mm, Temp. - 2 C., height of eye 6 feet. 



Meridian altitude Sun L. L. Sextant 17 30'; Ind. corr. + 6'. 

 Result: N. Lat. 81 17'.3. 



Though the two determinations of latitude of August 28 and 30 accord well, it must be 

 remarked that a series of altitudes taken the next year with the altazimuth on the same place, 

 gives the latitude nearly 5' smaller, which can only be explained by an elevation of the apparent 

 horizon on Aug. 28 and 30, similar to that found during the spring of the same year. As- 

 suming a correction of + 5' for both sets of altitudes of August 28, the result will be for 

 the Winter Hut: 



N. Lat. 81 13'.
