which appears to be to the south-west. However this may 
be, the whole series of beds seen at Cape ping rests finally 
on mica-slate, which itself appears to repose on the gneiss of 
Melazzo. After leaving the former place, however, the 
quartzy rock appears for some time to predominate, until we 
arrive -ata village called Giojusa, some miles west of the 
town of Patti, where it is seen at first curiously interlaced in 
thin strata, with a gray compact limestone, and afterwards 
giving place to that rock. This limestone contains several 
caverns, one of which was entered a few years ago, an 
feund to contain bones of some large animals, which, unfor- 
tunately, were not preserved. I explored another which had 
recently been discovered, but found no animal remains; the 
oor was covered with stalagmites, @ and a black mould. had

Between Guisa and Cape Orlando, we may obeerve- a 
repetition of the same slate formation as before, which is here 
of-very limited extent, speedily giving place to a red sand- 
stone, not micaceous like the former, and containing red iron- 
shot grains of sand, instead of angular fragments of quartz. 
This red sandstone continues all along the coast to Cefalu, 
uninterrupted, except by a bed or two of compact grayish 
limestone, used as a marble, and without petrifactions, 
This sandstone sometimes alternates with thin beds of 
shale, like that belonging to the coal formation. ’ 
The promontory of Cefalu consists of an isolated rock, 
which announces at a distance, by its bold and anupes 
that it is constituted of different materials - from those of the 
preceding country. It consists, in sesh of ibe a bluish fetid + hie

organic bodies, although gine are rarely reiids except on 
the weathered surface of the stone. I found them best ex-

hill of Cefalu, the stones of which indicate, by their gigantic. 
size, the extreme antiquity of the fabric. 
On the weathered surfaces, acted upon during so man 
ages, the petrifactions, as being the hardest portions, seed
