No. 6.| SLEDGE-EXPEDITION. OBSERVATIONS 1895. 123 
The sailing lasted from 3 p.m. to 8 p.m. and was followed by dragging over a belt of ice; 
estimated distance about 10 miles. The course seems to have been nearly true SW. Assuming 
er 
the distance between the two sets of observations to have been 5 miles, the change of latitude 
would be — 3:5, and of east longitude — 24' = — im 36s, which gives 9 = 30' nearly, and for 
the south side of Adelaide Island 
N. Lat. = 81° 37°7. 
For the afternoon observations g would then be 81° 34’ or Spy = — 1', and 
LT—I = 4h 10m 19s, E. Long. 45 7 7s — J = 61° 47' — J. 
1895, August 10. Bar. 758.4 mm, Temp. — 3°.6. Height of eye 6 feet, Ind. corr. (0). 
Meridian altitude Sun L. L, 28° 56‘; N. Lat. = 81° 30’. 
After rowing and dragging from 1 p.m. to 10 p.m. in a south-westerly direction (estimated 
distance 8—10 miles) the following Lunar Distance was taken: 
Watch I 7h 25m 29s, Sun and Moon 122° 37’; Bar. 758.2 mm, Temp. — 5°.3. 
Assuming Ind. corr. 0 as the day before, N. Lat. 81° 25’, LT—I = 4h 5m, the result is 
I—Gr. = — 0b 11™,8 
while the table p. 112 has — 0h 8m,0— 4. As the Ind. corr. was not determined on the same 
oceasion, and only a single distance was taken (the Moon disappeared during the observation) 
the result was not considered sufficiently accurate for a determination of 4 An index correction 
of + 4' would give accordance, with 4 = 0. 
1895, August 16. On Houen Island. Bar. 758.5 mm, Temp. — 1°.5. 
Hor. Point of Circle = 89° 51‘+ x, LT—I = 3h 50m + x 0.

A correction of + 10’ has been applied to the circle reading of the fourth observation. 
The assumed latitude, 81° 30’, is somewhat uncertain. On the preceding day and night the 
travellers were walking and rowing first NW, and then nearly west, but from Cape Felder the coast
