SURVEY OF THE BRITISH ISLES FOR THE EPOCH JANUARY I, I88G. 275 
corresponding stations were also taken on tke western side at about the same distance, 
and both on the Old Red Sandstone. Of these Mathon {l\2d) was 0'3 mile to the 
north of the latitude of Great Malvern, and the line joining them cuts the range at 
about a mile from its northern end, passing close to its highest point. Colwall (112a) 
is about three-quarters of a mile to the south of the latitude of Malvern Wells, and 
the line joining them cuts the range about 2^ miles south of the northern termination 
of the igneous rocks. 
The Declination and Force were determined at all these stations. Time did not 
allow of the Dip being taken elsewhere than at Great Malvern. 
The results are given in the following Talde —

The accompanying Map shows the direction of these forces and tlieir relative 
magnitudes. The Worcestershire Beacon (1440 ft.) is the highest point on the range ; 
to the south of this the height diminishes, and then increases again to the Hereford¬ 
shire Beacon. The directions of the disturbingf forces tend towards these hills, and 
the results are, we think, only compatible with the view that the Malverns attract the 
north-seeking pole of the magnet.
