author, who has attended very particularly to 
the appearances presented by basalt in many 
parts of the world, in the beds of rivers, in 
lakes, and in the sea ; and has traced them 
almost the whole way from the north coast of 
Ireland, through all the Hebrides, to Iceland; is 
convinced that this regularity of structure in 
basalt is entirely owing to crystallization. The 
original deposit whence the pillars in this place 
were derived, does not lie far from the road- 
The strata on each side consisted, for the most 
part, of limestone ; but we observed a subjacent 
bed of schistus, containing greenish actinolite : a jcHnoUte.

might be selected exhibiting the appearance of 
the people over whom JEneas, retiring up the 
country, is said to have reigned, after the
