On certain Newer Deposits in Sicily, and the Phenomena 

 accompanying their Elevation. By Dr Alexander Tuen- 

 BULL Christie, M. W. S., F. G. S., &c. &c. Communi- 

 cated to the Society by Roderick Impey MuRCftisoN, Esq. 

 President of the Geological Society, and read November 2d 

 1831 *. 



JL he following observations on the geology of Sicily, being the 

 result of a very rapid excursion through that island, are neces- 

 sarily very imperfect ; but as they may probably tend to throw- 

 some light upon disputed points regarding the age of the Sici- 

 lian formations, and upon some of the theories which at present 

 excite the interest of the geological world, I hope 1 may soli- 

 cit for them the attention, as well as the indulgence, of the So- 

 ciety. 



After having spent a few days at Palermo, I travelled along 

 the northern coast as far as the Castello de Tusa, crossed the 

 central chain of mountains, by way of Mistretta, and the Monte 

 di Castelli, to Nicosia, Leonforte, and Castro Giovanni ; turned 

 easi\vard by way of Santo Pilippo d'Argire to Catania, and 

 proceeded along the east coast by Lentini, Syracuse and Noto, 

 to Cape Passero, where I embarked for Malta. 



• This interesting memoir of our friend and pupil Dr Christie, at present 

 engaged in examining the geological structure of Palestine, was transmitted 

 by him from Malta to Mr President Murchison, to be read before the Geo- 

 logical Society, and afterwards published in the Edinburgh New Philoso- 

 phical Journal. A Geological map of Sicily, by Dr Daubeny, will be found 

 in vol. xiii. of Edinburgh Philosophical Journal. — Edit.
