it is impossible for me at present to attempt CHUMICRaAae their 
species. 
I do not know whether any siratificationf’can{be discov- 
ered in the rock of Cefalu;. there is indeed a kind of separa- 
tion into three distinct masses, but these 4ook rather like the 
result of cleavage, which may take place in every rock, even 
down to peanite, than the effect of a deposition at distinct 
riods. 
Indeed, the rock itself seems to split irregularly, ina . direc- 
tion just opposite to that of the nearly horizontal seams above 
noticed. 
The whole of this calcareous formation Tests upon the 
sandstone just described, and may be referred to the one = 
hills, which, under the name of the apenas Range 
seen in the ‘back ground, running nearl parallel to the thee 
coast, between-Cefalu and Termini, and from thence extend- 
ing to Palermo, and perhaps to Trepani 
It should seem, however, that this is ‘the only spot within 
ras limits of this formation, in-which organic remains have

It is generally of a Bhaishi colour, anid is then often found 
to emit, when struck, a fetid odour like sulphur ; sometimes, 
however, it is white, and of a compactness not much exceed- 
ing that of the hardest kind of chalk, or of the beds which 
are cecasionally met with in the Jura limestone.
