Survey of Northeast Greenland. 
Determination of latitude, 
Determination of time and azimuth, 
Trigonometric station pointing, 
Sketching survey. 
Besides a barometric levelling ought to have been performed, 
but the barometer and thermometer were not read off at all; why I 
don't know. 
Determination of latitude.

The temperature may Бе estimated at 0, the pressure at 680 mm,

This rough and ready computation of the latitude is in this 
case sufficient, because the temperature and pressure are not mea- 
sured, for which reason the refraction cannot be determined with 
the necessary certainty. 
Observation of time and azimuth (temperature and pressure 
as above).
