HE Scheme of work for the Norwegian North Polar Expedition 1893 

 1896 included Meteorological Observations, comprising the direction and 

 velocity of the wind, the pressure, temperature, and humidity of the air, the 

 amount, form and motion of the clouds, the nature and amount of the preci- 

 pitation, the direction of the motion of the waves, the state of the sea, the 

 temperature of the sea-surface, and phenomena of occasional occurrence. 

 During the drift of the Fram, the temperature of the ice at different depths, 

 was also observed. 



The instruments had been verified at the Meteorological Institute in 

 Christiania before the departure of the expedition. 



During the expedition, the observations were organized and superin- 

 tended by Capt. S. SCOTT-HANSEN. His assistants were Lieutenant (now Capt.) 

 HJALMAR JOHANSEN until the beginning of 1895, and after that time Mr. B. 

 NORDAHL. SCOTT-HANSEN or his assistant made, as a rule, all observations 

 during the day. During the night, the observations were taken by those 

 members of the expedition who had the watch. After the return of the 

 Fram to Christiania, the instruments and the journals containing the ob- 

 servations were handed over to the Meteorological Institute, where the instru- 

 ments brought back were compared with the standards, and the observations 

 worked out under my supervision. In addition to the observations from 

 the Fram, Professor NANSEN sent me the observations taken during the 

 sledge-journey to Franz Josef Land, the wintering in the hut, and the 

 journey to Cape Flora. 



In this memoir I shall first describe the instruments employed at the 

 Station Fram, and the mode of using them, as also the reduction of the
