 in motion 5 and wliicli^ altliongli stony and capable of snp- 

 porting lieaA^y weiglits, may be upraised witliout bursting by 

 tlie intumescence of the melted matter below. The reader 

 may also be reminded of the upheaval of a solid crust of lava 

 witnessed by Abich within the crater of Vesuvius in the 

 year 1834^ already mentioned by me. (VoL L p. 629.) That 

 the upheaval was merely local is proved by the fact that 

 the neighbouring Kaimenis did not participate in the move- 

 mentj still less the three more distant or outer islands.
