EQUIPMENT. 



Magnetic Instruments. 



A set of terrestrial-magnetic variation instruments with photographic registering apparatus and lamp 

 reflector of the Eschenhagen pattern from Otto Toepfer's, Potsdam. 



An Eliott Brothers' unifilar magnetometer, belonging to the observatory in Christiania. 



An inclinatorium, lent by Professor Rydberg, and previously used on the "Vega" expedition. 



An earth-inductor, from G. Schulze in Potsdam, with galvanometer made by O. Pluth, Potsdam. 



Earth-current Apparatuses. 



Two Deprez-d'Arsonval galvanometers from Keiser & Schmidt, Berlin. As these instruments proved 

 to be bad, one of them afterwards had to be exchanged for one from Hartmann & Braun, Frankfort- 

 on-the-Main. 



A registering apparatus with accessories, resistance-boxes, cables with rubber insulation, etc. 



Meteorological Apparatuses. 



A mercurial barometer. 



A thermometer-screen with its thermometers, and spare thermometers. 



A large barograph. 



A large thermograph with forms, from the Meteorological Institute in Christiania. 



A cloud-measuring apparatus, an anemometer from Richard Freres, Paris, etc. 



Electrical Apparatuses. 



An Elster & Geitel's electroscope with accessories for observations of dissipation of electricity in 

 the air. 



A Zamboni battery, with wires, insulators and tightly-closing drum, from Gunther & Tegetmeyer, 

 Brunswick. 



Astronomical Instruments. 



The station had no permanent theodolite, as it was in telegraphic communication with the astrono- 

 mical observatory in Christiania. The azimuth 

 of the mark (the spire of Kaafjord Church) was 

 found by Saeland with a large theodolite in the 

 autumn of 1902, before he left for Iceland. 



The expedition had borrowed from the 

 Military College in Christiania a box-chronometer, 

 Kessel 1390. 



They also took with them books, papers, 

 etc., rifles, ammunition and provisions, as some 

 time was to be spent at the Haldde obser- 

 vatory. In Kaafjord, the members of the ex- 

 pedition put up at the Kaafjord Copper Mines.
