This paper is a continuation of the preceding one. It consists of two sections, the seventh and eighth. In the seventh section the author discusses the secular change and annual variation of the declination; and in the eighth section, the annual variation or semiannual inequality of the inclination and of the horizontal and total magnetic force. Seventh Section.—The positions of the horizontal magnet at 24 equidistant epochs in the day, tabulated from the photograms of the Kew declinometer, with the omission of the disturbed observations, as described in the former paper, are grouped in weekly means, forming 52 mean values, corresponding to the number of weeks in the year.
