This paper is a sequel to our former one relating to the daily magnetic variation, on really quiet days, at Eskdalemuir and Greenwich. Here we extend the investigation to four more magnetic observations; the principal relevant particulars for the whole six observatories are as follows:— The last three columns give approximate mean values of the three magnetic elements, H (horizontal force), Z (downward vertical force) and declination. The stations range over 75° of geographical latitude, and 85° of magnetic latitude (i. e ., latitude with respect to the earth's magnetic axis).
