According to this there is every reason to suppose that the position 

 of the mirror in relation to the axis of the magnetic needle has shifted 

 somewhat during the Expedition ; but as, owing to the always unsettled 

 magnetic conditions, the observations afford no opportunity for investi- 

 gation as to when such a displacement may have taken place, it has 

 been impossible for me to make a calculation of the absolute declination 

 answering to each separate position of the needle. 



Nor is this necessary, as fortunately in each determination of declina- 

 tion, the same number of settings of the needle was made in each of 

 the two positions, P, and P^, thus eliminating the error of coUimation. 



THE AZIMUTH. 



The determination of the azimuth of the mark, a, was made by 

 Captain Baumann at all four stations by the aid of solar observations, 

 with the following result, a being reckoned positive from the south point 

 through west:
