1898-1902. No. 6.] TERRESTRIAL MAGNETISM. 



a pedestal of ice, upon which, frozen firmly to it, lay a 

 slab of stone, the instrument being placed upon this. 

 When spring arrived, the roof of the hut was removed. 



At Station I b the observations were made under the 

 open sky. A large erratic block, that was firmly em- 

 bedded in the ground, was used as a pedestal; and upon 

 this, in the winter time, a lantern was placed to serve 

 as a mark for the sights taken at Station I a. 



When the instruments were moved over from the 

 south to the north side, the ice pedestal was removed from 

 Station la, and in its place a vertical rod was set up 

 in such a manner as to pass as accurately as possible 

 through the point at which the centre of the instrument 

 had been. This rod served as a mark for Station I b, 

 where observations were made for the determination of 

 the azimuth of the line of connection. 



Station II. Havne Fjord, r/. = 76° 29', A = 84° 4' W. 



The observations were made on land, under the open 

 sky, at a distance of about 500 metres from the Fram. 

 A large block of stone was used as a stand for the in- 

 struments. The mark was a rod set up vertically in a 

 direction ENE, at a distance of about 500 metres from 

 the place of observation. 



Between the 26th June and the 3rd July, 1900, a 

 series of determinations of all the three elements was 

 made at this station by Captain Baumann, and between 

 the 20th July and the 3rd August, a new series of ob- 

 servations by Captain Isachsen. 



Station III. Gaase Fjord, r/) = 76° 49', 1 = 88° 40' W. 



The observations were made on land, under a tent, 

 by Captain Baumann, from the 2nd to the 22nd July, 

 and on the 11th August, 1901, at a point situated at a 

 distance of about 800 metres in a direction S 30°E from 

 the Fram. A large block of stone was used as a stand 

 for the instrument. The mark, a vertical rod, was placed 

 at a distance of 400 metres in a direction E 3i°N. 



Station IV. Gaase Fjord, f = 76° 40', A = 88° 38' W. The 

 observations were made on land under a tent at a dis-
