APPENDIX 3.

OBSERVATIONS OF THE MEAN MAGNETIC INCLINATION, MADE ON Sh.o.r.e IN THE VOYAGE OF H.M.S. RATTLESNAKE, BY LIEUTENANT J. DAYMAN, R.N.

INSTRUMENTS EMPLOYED: ROBINSON'S 6-INCH INCLINOMETER; FOX'S DIPPING APPARATUS.

The following tables contain the absolute determinations of the magnetic inclination and declination made in the Voyage of H.M.S. Rattlesnake on sh.o.r.e. A very large series made almost daily at sea with Fox's instrument and the Azimuth Compa.s.s require several corrections before they are fit for publication.
