the Dalmatian isknd of Meleda, 16 miles from. Bagusa, from March 1822 to 

 September 1824, was occasionally accompanied by shocks. Much light has 

 been thrown on this phceuomenon by Partsch.

 filled to the brim with water exhibited agitation for several hours. 



( 189 ) p. 199. The Spanish expression is, "rocas que hacen puente." These 

 local interruptions to the transmission of the shock through the zipper strata, 

 seem analogous to the remarkable phenomenon which took place in the deep 

 silver mines of Marienberg, in Saxony, at the beginning of the present cen- 

 tury, when earthquake shocks drove the miners in alarm to the surface, where, 

 meanwhile, nothing of the kind had been experienced. The converse phseno- 

 menon was observed in November 1823, when the workmen in the mines of 

 Palun and Persberg felt no movement whatsoever, whilst above their heads a 

 violent shock of earthquake spread terror among the inhabitants at the surface.
