SLEDGE-EXPEDITION. OBSERVATIONS 1895. 



115 



northwards of 10 miles during the 4 hours of travelling, which is certainly too much considering 

 that the ice was very rough ; on putting <p = 86 0' or 4y = 5', the result is 



LT-I = 5h 54m 38s an d E. Long. = 6^ 47m 498 ioi<> 57-. 

 The two observations by compass will then give: 



Magnetic Declination 47.0 and 46.6, Mean 46.8 E. 



As the course was laid considerably more westerly on one of the first days of April, and 

 certainly not later than April 4, it is, however, possible that the correction Jh should have 

 been somewhat smaller than the day before, which would also give a smaller longitude. 



1895, April 7. Bar. 30 in., Therm. - 35.5. Height of eye 24 feet, Ind. corr. 0. 

 Meridian altitude of Sun L. L. 10 27', which gives N. Lat. = 86 12'.3. 



This was the most northern place of observation. Mr. Nansen walked about a mile farther 

 north in order to get a view of the ice before returning. The meteorological conditions being 

 the same as the days before, it is probable that the latitude has been some minutes less. 



1895, April 8. Bar. 30.48 in., Therm. - 36. Height of eye 24 feet, Ind. corr. (0?). 

 The following 3 altitudes were taken on the same place as the day before, and were there- 

 fore reduced with the latitude 86 12'. 



Employing the same value of 4h as above, and assuming the elevation of the horizon to 

 have been the same at noon as in the morning, or 4<p = 4h, the result is 



LT-I = 5t 268 + 5m.l = & 31^.9, and E. Long. = 6^ 25. 9 = 96.5. 



1895, April 13. Bar. 29.90 in., Therm. - 30. Height of eye 12 feet, Ind. corr. + 5'. 



The following observations were not taken exactly at the same place, the morning ob- 

 servations with sextant and compass having been made at a camping-place reached the preceding 

 day, while the meridian altitude was taken an hour or two after the departure therefrom.
