It was evident that no good result could be obtained without an extra
declinometer, Owing to the necessity of reversing the needle, in Order to
eliminate the changes of declination, when the slightest alteration of position
would have far more ...

obtain a declinometer (Figure 1.9), an 8-inch dip circle and a sidereal ...
