the latitude, therefore, 14" too far north, and the longitude 

 about 30", or 2' (310 metres), not far enough east.

7. Vardø. 



The observations were tåken on the 26th of .lune. 

 1878, about noon, from a point which, as determined with 

 the tlieodolite. lies 175 metres north and 51 metres west 

 of the centre ofVardøhus fortress. The atmosphere, clear 

 åt first, soon got hazy, so that the last series of altitudes 

 bad to be tåken with light-coloured glasses. and ere 

 long the observations bad to be broken off. the sky be- 

 coming quite overcast. Hence, I did not succeed in getting 

 an equal number of altitudes of each solar limb; and the 

 index-error was not very well determined. As a mean .ol 

 4 observations. the index-error was found to be -4- 2' 13" 



On this occasion, I observed with my pocket-chrono- 



meter.
