The following table contains the resulting values of the hori- 

 zontal intensity; those of the total intensity thence deduced, 

 and the latitudes and longitudes of the stations. The dips 

 employed in deducing the total from the horizontal intensities, 

 are given in Table XXXIX; the London dip used in the com- 

 putation is the mean dip at Westbourn Green (Table III.)j 

 reduced to the mean epoch of the present series.
