Very unsteady. 
Unsteady. 
A less delicate point 
was used for the 
suspension of the 
compass-card, 
which made it 
much steadier. 
> + 26 16 
Card steady. Being 
a calm the decli- 
nations were ob- 
served on different 
points of the com- 
pass to obtain the 
effect of the ship’s 
iron. The com- 
pass was after- 
wards placed in a 
copper-fastened 
boat and the de- 
clination observed 
at a distance from 
the ship. 
Compass steady. 
> + 28 56 
;t3ady. 
This observatiop is not much to be depended on, as the compass was very unsteady and difficult to ob- 
serve.
