On the Ice Near the Ship. 



The oscillations were performed in the snow-hut in which the magnetic 

 observations had been carried out. The iron cross for the pendulum appa- 

 ratus was placed on the ice itself, to which it froze so firmly, that the bubble 

 of the level did not move as much as one division. The pendulum oscillated 

 from about NW to SE, the direction being determined by the compass on board 

 and the bearings of the stand. The angle made by the plane of oscillation 

 with the diametral plane of the vessel measured 39 + 2. The position was 

 the same on the three days, the 8th, 10th and llth June. The pendulum 

 clock Hawelk was compared with the chronometer Frodsham.
