ADEN DIP OBSERVATIONS.
The following observations for inclination were taken with a dipping circle by Robinson,
six inches in diameter. It is supported on three screw feet, by which an azimuth circle,
divided to single degrees, is levelled. This again is read off by pointers easily read to one-tenth
of a degree, and the pointers are at the extremities of arms fixed to a brass pillar that can be
moved in azimuth and support. The vertical or dip circle which supports the agate planes
on which the axle of the needle revolves, is divided into fifteen minutes. The instrument
is provided with four new needles from Robinson, the maker, to whom it was in 1819 sent for
repairs, and it is in first rate order. Each determination is taken in the usual way with
sixteen readings after the needle has become at rest.
The observations are entered as follow
(In column A.) The observations are taken with north pole at the marked end A., and with
the face of the needle on the same side as the face of the dip circle, and with the face of the dip
circle towards the E.
