TERRESTRIAL MAGNETISM. 



TABLE 124. Horizontal Intensity. 



This table gives, for the epoch January i, 1885, the horizontal intensity, H, corresponding to the longitudes in the top 

 line and the latitudes in the body of the table. At epoch 1885 the force was increasing for positions above the 

 division line, and was decreasing for positions below the division line. 



TABLE 125. Secular Variation of the Horizontal Intensity. 



Values of the horizontal intensity, H, in British units, for stations given in first column and epochs given in top line. 

 The values for 1890 and 1895 have been extrapolated from the values up to 1885. The epochs are for January i of 

 the different years given.
