 the Memoirs of the Palicoiitographical Society; its total height before loss 

 of apex was probably 4.') mill., as even now, after mntilation, it attains 40 

 mill.; its breadth is 21 mill. The apertnre is 20 mill, long and 10 mill, in

1 ("'.eologists speak of Sconce as if it were a geographical place. Sconce is a common noun, meaning a 

 fort (to ensconce was to retire into the sconce for defence), and was applied to the defences of Tudor and 

 Stuart times, which were often distinguished hy the names of the erectors. This one is marked on sorne 

 maps as Gary's Sconce (now demolished). The Bembridge limestone is exposed near its site, hence its 

 notoriety, C. Ashford in lilt., 1S9U.
