MAGNETIC OBSERVATIONS.
[Chap. XI.
1842

The proper season for resuming our operations in the south being now at hand, our observations were concluded in the early part of December, and the ships made ready for sea.

The meteorological abstracts and remarks are printed in the Appendix.

The result of our magnetic observations gave the mean dip, and variation for each month as follows:—

Variation. Dip.
For April 17° 50′ 18″ E. 52° 26′ 1″
May 43 47 25 7
June 38 10 25 5
July 35 39 22 4
August 33  0 23 1
September 32 19
October 30 10
November 27 33 18 8
December 16 1

The latitude of the observatory 51° 32′ 5″ S., and the longitude 58° 7′ W.
