NO. 6.] SLEDGE-EXPEDITION. OBSERVATIONS 1895. Lal 
The weather being still clear and calm with severe cold, the former value of 4h may be 
assumed, and 4p = — 4h for noon; the difference of 2’ from morning to noon assumed above 
being perhaps somewhat small, the morning latitude has been taken as 85° 34’, or 4p = — 6’. 
As the observations were taken very near the prime vertical, its influence is very small.

The meridian altitude, which gives y = 84° 47', was taken at the camp of the preceding 
day, while the other observations were made nearly 4 hours after the departure from this place.
